This is the thread where we post noteworthy graphs or quantitative diagrams. Ones you've done yourself are especially welcome but, so this doesn't turn into me live-blogging my PhD, any cool graph is welcome.

Here is my bro IC 5096. The black lines are contours of constant surface brightness of an image taken on a telescope outside Sydney in 1997. The red lines are my model galaxy, which is supposed to match the black lines. It does OK.

The axes are in units of arcsec, which is an angle rather than a distance. 1 arcsec = 1/3600th of a degree (i.e. not far). This galaxy is 40 Mpc = 130 465 450 light years away. At this distance 50 arcsec corresponds to about 10 kpc = 30 000 light years. This is about the distance from us to the centre of the Milky Way.

That finger of god thing is what a perfectly spherical cluster of galaxies at a very large distance ends up looking like from Earth.

http://www.nature.com/nature/journal/v410/n6825/full/410169a0.html

This redshift-space anisotropy should cause two characteristic effects, operating respectively on small and large scales. On small scales, random orbital velocities within galaxy groups cause an apparent radial smearing, known as 'fingers of God'. Of greater interest is the large-scale effect; if cosmological structure forms by gravitational collapse, there should exist coherent infall velocities, and the effect of these is to cause an apparent flattening of structures along the line of sight.

bong hit time.

The community has red edges and sits over the network of all neighbours of the nodes in the community. All of the rappers with several exceptions such as Chuck D, Isaac Hayes, and Chris Rock are directly or indirectly affiliated with the Wu-Tang supergroup and their music labels. The highly clustered rappers in the middle of the diagram are the core members of the original Wu-Tang Clan group (GZA, RZA, Ol' Dirty Bastard, Method Man, Raekwon, Ghostface Killah, Inspectah Deck, Masta Killa, U-God).

What is a negative unemployment rate? Unfilled jobs/people?

caek, Tuesday, 6 November 2007 18:15 (sixteen years ago) link

I think there's a negative correlation between inflation and the unemployment rate so they've reversed the unemployment axis for some reason: maybe to illustrate the similarity of the shape.

Noodle Vague, Tuesday, 6 November 2007 18:19 (sixteen years ago) link

Ah, so by "(Minus) unemployment rate" they mean "unemployment rate x -1". In which case:

It's probably a galaxy cluster. Contours are probably the same object at another wavelength, e.g. X-ray, which is a good thing to look at clusters in. Distance scale is much too small for the Great Wall and too large for a nebula.

What is your model made of? What is it supposed to be used for when it works?

El Tomboto, Wednesday, 7 November 2007 21:18 (sixteen years ago) link

I make models of disk galaxies. They are ones that happen to be oriented edge-on to us so they look more like http://en.wikipedia.org/wiki/Sombrero_Galaxy (but even more edge-on) than http://en.wikipedia.org/wiki/Messier_81. This makes it harder to work out whether they have spiral structure or bars than ones that are face-on, which you can just look at.

The idea is I take an image of the edge-on galaxy, add up the mass along the line of sight and predict how the stars in a perfectly asymmetric galaxy with that mass distribution would move. I then compare this to measurements of the stars movement (I will show these soon). If I can't get, e.g. model and data velocity-radius curve to match in the central region then I can conclude that the galaxy is not perfectly axisymmetric and probably has a bar. Another product of this fitting process is the mass-to-light ratio. If M/L > 1 then we either have stars heavier than our sun for the amount of light they produce -- or dark matter.

That is the big idea, anyway. In practice I end up doing things like what I've been up to for the past fortnight, which is basically dealing with a shortcoming of my data, which is good in some regards, but poorly calibrated. This involves futzing around with numbers until my lines match the lines for the same objects published by the big, very accurately calibrated surveys.

caek, Wednesday, 7 November 2007 21:29 (sixteen years ago) link

(link removed)

^^^ example of comparing my the velocity curve of my mass models to the data. That's a pretty good fit. M/L is worryingly high, but I know why that is. I need to regenerate all these plots.

caek, Wednesday, 7 November 2007 21:32 (sixteen years ago) link

What do you use to make your figures, caek? I do a lot of work on graphics, mostly because it seems there is a sizable group of authors using plotting software that they wrote themselves, and the fonts and/or colorspace get messed up. Also, IDL can eat my balls.

caek, Wednesday, 7 November 2007 21:54 (sixteen years ago) link

Ahahah I thought so! :) The big thing is that in my experience, IDL does not know the difference between RGB and CMYK. It may say it does, but it doesn't.

dan m, Wednesday, 7 November 2007 21:55 (sixteen years ago) link

Pretty much all astrophysicists do. There are movements toward Python, mainly coming from the Hubble dudes, but there is an awful lot of entrenched code. I'm not convinced Python's graphics capabilities will make journals' lives a lot easier anyway, although it is a much nicer language.

I'm going to redraw my figures for publication in Illustrator. It's what Tufte would do.

xp: opportunity to procrastinate, yay. Two options.

One is to plot the year of release against the year of adoption. The further above the line y = x the points are, the later it was adopted. You'd probably label the points with, e.g. "Pentium" or whatever rather than just put crosses.

http://i50.photobucket.com/albums/f325/caek/Picture1-3.png

Another is to plot the lag before adoption (i.e. adoption - release). The further above y = 0 the later the adoption.

caek, Wednesday, 12 March 2008 19:09 (sixteen years ago) link

Sorry. Actually, that should be pretty easy in Excel. Set up three columns of data:


1988 1998 1988
1992 1993 1992
1994 1995 1994
1995 1998 1995
1998 2000 1998
2003 2007 2003

Then plot column 1 (release) vs column 2 (adoption) as points and column 1 vs. column 3 (release again) as a dotted line.

That may be a retarded way of doing it in Excel. I haven't used it since the Pentium II.

yeah, they're pretty much identical areas, but mine is narrower because my exposures were longer than they others are so I see more of the disk.

ice cr?m, Sunday, 30 November 2008 17:57 (fifteen years ago) link

listen man I am a lay person who reads magazines my opinions are informed

TOMBOT, Sunday, 30 November 2008 17:59 (fifteen years ago) link

There is there is no dark matter research, but I wouldn't say I was part of that. I'm more, "OK, dark matter works well on large scales, but things get problematic when you throw some visible matter into the mix, and this is precisely how problematic...".

There's no question that there are discrepancies between the amount of visible mass and the speed with which we see things move (e.g. stars in galaxies). That is an empirical fact that everyone agrees on and it's the observational motivation for "invisible matter that makes things move fast", i.e. dark matter. (The other observational motivation is that time jhosh saw it.)

The other way to explain these disceprancies is Modified Newtonian Dynamics (MOND), which is modifications to Newtonian Gravity on very large scales. If you're interested then a good chatty introductions to the merits of the two is James Binney's 2003 address to the IAU in Sydney, which you can read here: http://arxiv.org/pdf/astro-ph/0310219v2.

Basically, my understanding is that both both dark matter and MOND are fits to data rather than predictions motivated by theories. E.g. Dark matter would probably not have dropped out of theories of particle physics or field theory unless cosmologists had told particle theory people to go looking for it. But dark matter in particular works very well in a lot of situations.

I confront the predictions of dark matter with observations of rotation in galaxies, and they don't match, so the question is what's the problem. Perhaps dark matter is just plain wrong. More likely, I think, is that the models of dark matter (which is simple stuff in itself) do not correctly incorporate "baryonic physics" (things like star formation, black holes, feedback, hydrodynamics, etc. which are all terribly complicated). So on scales where these processes are important, like individual galaxies, things break down.

Dark energy is another matter though. That's some bullshit right there.

caek, Sunday, 30 November 2008 21:39 (fifteen years ago) link

http://i50.photobucket.com/albums/f325/caek/Picture5.png

Here's me confronting some predictions with some observations. Each plot shows the speed at which the stars in a galaxy are rotating (in km/s on the vertical axis) as a function of distance from the centre (in weird units you don't need to care about). The observations are the points. The red lines are the predictions of models. Above each plot are the parameters of those models. The first number is the number of solar masses we ascribe to each unit of solar light we see. The second number is the amount of dark matter (in units of solar masses and then logarithmed for those of you playing along at home).

So the point it this:

Take the top left plot. The first number is 0.5 so we're saying each sun we can see weighs half as much as our sun. And we've got a 1 with ten 0s after it dark matter. And the model does not rotate as quickly as the real galaxy.

So we add more dark matter (plots to the right) and more visible matter (plots to the bottom) until we get the best fit. The best fit gives us an estimate of the amount of dark matter present. The best fit here is probably about 1 with twelve 0s dark matter.

caek, Monday, 1 December 2008 20:32 (fifteen years ago) link

I was just reading the new scientist story on how another possible explanation for the discrepancies could be that the copernican assumptions of our postal code being somewhere in a universal kansas are incorrect, or at least the assumptions about the attributes of said kansas

El Tomboto, Monday, 1 December 2008 20:45 (fifteen years ago) link

yes, that would do it. again though, all these are post facto fits to observations and not predictions : (

Video Created by Scott Manley, this is a view of the solar system showing the locations of all the asteroids starting in 1980, as asteroids are discovered they are added to the map and highlighted white so you can pick out the new ones.
The final colour of an asteroids indicates how closely it comes to the inner solar system.
Earth Crossers are Red
Earth Approachers (Perihelion less than 1.3AU) are Yellow
All Others are Green

Notice now the pattern of discovery follows the Earth around its orbit, most discoveries are made in the region directly opposite the Sun. You'll also notice some clusters of discoveries on the line between Earth and Jupiter, these are the result of surveys looking for Jovian moons. Similar clusters of discoveries can be tied to the other outer planets, but those are not visible in this video.

As the video moves into the mid 1990's we see much higher discovery rates as automated sky scanning systems come online. Most of the surveys are imaging the sky directly opposite the sun and you'll see a region of high discovery rates aligned in this manner.

At the beginning of 2010 a new discovery pattern becomes evident, with discovery zones in a line perpendicular to the Sun-Earth vector. These new observations are the result of the WISE (Widefield Infrared Survey Explorer) which is a space mission that's tasked with imaging the entire sky in infrared wavelengths.

The scale of the video at 1080P resolution is roughly 1million kilometers per pixel, and each second of video corresponds to 60 days.

Currently we have observed over half a million minor planets, and the discovery rates show no sign that we're running out of undiscovered objects, scientific estimates suggest that there are about a billion asteroids larger than 100metres (about the size of a football field) .

maybe that includes people who think they're working out, but it's controversial among people that really do work out. e.g., people who walk to work and think of that as working out since other people will walk a mile after work in sweatpants and count THAT as working out. that probably accounts for the overlap. and then you add in the people who are asleep and dreaming that they would work out if it weren't all hard and stuff (these people, when awake, actually do work out, or think they're working out, but it's controversial). and where all three of those sets meet - all of those people use the speck iPhone case.

i was doing my routine morning data analysis on my thread posting history when i decided to "dig deeper" into the data and create some "data visualizations", aka charts. here's a line graph showing the number of threads i've posted over my many years on ilx (many more years than any other ilx poster):

note that for 2014 i took the number of threads i created in the first 6 months (15) and extrapolated that to an estimated 30 new threads for the entire year.

science projects that i'll post 29 new threads in 2015. but let's dig deep into the data and see what polynomial theory has to say:

http://i.imgur.com/LdSxdPh.png

the second order of polyscience suggests that my output will decline to a similar degree, to around 28 threads in 2015. but what if we "dig deep" into the data and take it to the 3rd order? what then?

http://i.imgur.com/nzbC5sK.png

3rd order science appears to be making a surprising prediction: 50 new threads in 2015. on the way to the store to buy arthritis ointment i program my computer to take it to the next level and take the polynomial theory to the 4th order:

http://i.imgur.com/vh1X8oi.png

42 is the prediction for 2015. finding: polynomial theory appears to create trendlines that are different depending on the order. let's dig deep and reach for the 5th polynomial order:

http://i.imgur.com/J7XMQP1.png

astonishing: the deeper you dig into the data, the fewer answers you come up with. the theoretical 5th order projection is 16 new threads created in 2015. the farther i look with my mind, the smaller i become, in terms of my ILX presence. i am disturbed but also confused and angry at science, which appears to contradict itself. as i gather the kindling to make the bonfire that will burn my books of science and polynomial theory, i remember that there is one more order that can be achieved with the proper formula: "the sixth order of polynomial order".

again, you may want to sit down for this.

knowing what was to come, i sat down and produced this:

http://i.imgur.com/ticccQk.png

i will create over 500 threads in 2015. as this is the latest data i have obtained, i know that this projection is the most accurate. i am preparing to create 1.37 threads a day in 2015, all in tribute to science and order.

I've been making graphs for my company for the past year or so, and with no formal training, I still feel like this newspaper is publishing the rantings of a crazy person.

For example, we used to measure net absorption rates in regular bar form, like this:

http://assets.inarkansas.com/32941/net-absorption-by-quarter.jpg

Net absorption is such a weird stat anyway - Basically how much square footage was gained or lost in a market between two quarters. It can be positive or negative. And if a shopping mall opens or a factory closes, the numbers can vary widely.

So I wanted to show how big of a difference those numbers can be sometimes and came up with this:

http://assets.inarkansas.com/49176/central-arkansas-industrial-real-estate-vacancy-553.jpg

The marks we would've used in bar formats are still there, but I represented the rates by size. The time used above was a good one since everything was positive, but if any were negative, I could've still used the space I've got and just put the zero line in the middle. Like this:

http://assets.inarkansas.com/49054/vacancy-rate-remains-flat-781.jpg

Are those too busy? Do they make any sense? What changes would you make?

I get a little lost in the woods some afternoons I'm putting these together. No one's complained yet, but hell, who knows if anyone's even looking.

Different sized circles are usually bad for data visualization, because they're easy to mess up and can be difficult to interpret.
http://blog.revolutionanalytics.com/2011/01/for-data-visualization-circles-dont-cut-it.html
And also see the discussion in Nathan Yau's book Visualize This.
But circles might be pretty good to use if you're using them to represent area (or change in area) like you are. Just make sure the circles actually represent area, and you're not accidentally sizing them by radius or diameter.

Dan I., Wednesday, 9 July 2014 18:39 (nine years ago) link

Hm, I think using both circle size and the Y axis to represent net absorption might be bad, because it makes the circle sizes more difficult to compare. If you want to represent net absorption by circle size, consider taking out the Y axis and just setting all the circles on the same horizontal line.

Dan I., Wednesday, 9 July 2014 18:42 (nine years ago) link

pplains, are you trying to demonstrate that the changes are mostly capricious/random or just that they can vary widely year-to-year? from looking at these i'd guess that something happened in 2013 4Q that lead to a huge boom in both commercial + industrial sectors?

Mordy, Wednesday, 9 July 2014 18:45 (nine years ago) link

I also think different sized squares would be a more easily interpretable indicator of area, because people aren't as good at perceiving that the outer parts of a circle contain more area (the famous "biggest pizza = best deal" thing)

Dan I., Wednesday, 9 July 2014 18:46 (nine years ago) link

(Also, Dr. Malone, get one information criterion!)

Dan I., Wednesday, 9 July 2014 18:47 (nine years ago) link

one problem with the circles (as used above) is that it can difficult to tell at a glance what the actual quantities are - is it the point at the middle of the circle? at the top edge? bottom edge? reasonable people could come to different conclusions, i think. it's really impossible to tell without labeling each of the individual circles, which you've done. but if you have to label each of the individual circles in order to communicate the quantities, then there's probably a better way to do it. also, Dan I otm about area vs radius vs diameter

Karl Malone, Wednesday, 9 July 2014 18:49 (nine years ago) link

And especially since some of the values are negative, it's better to just stick with the bar chart in your first image. Really feel like the human brain might have a problem interpreting the size of a thing on a plot as actually being the magnitude of the reduction in that thing.

Dan I., Wednesday, 9 July 2014 18:55 (nine years ago) link

you could implement a new system where you walk around the office giving tootsie rolls for every 1000 sq. ft. of net office space gained that quarter. if your company loses office space, then you take away an item on the person's desk for every 1000 sq. ft. lost. this simultaneously acts as an incentive system

You could change the unit from square feet to "# of john's houses" to point out to everyone how small your rival john's house is.

chikungunya manatee (Sufjan Grafton), Wednesday, 9 July 2014 19:03 (nine years ago) link

at the least there is a problem with the x positions of the circles. they are not regularly spaced in the x direction. is that real?

those plots are very hard to interpret imo. estimating areas of circles is something we are always terrible at. but in this case it's even harder because what you're trying to get across is conceptually complicated, and the range of point sizes you're using is colossal.

the bar chart in the first example is much clearer. i would stick with that tbh. if you want to explicitly include both the absolute value of SF and the change (i.e. net absorption) (which i don't think you need to, it's implicit, unless i've misunderstood net absorption), i would use two bar graph panels, one above the other, sharing an x axis

x = time
y1 = square feet
y2 = net absorption

caek, Wednesday, 9 July 2014 19:05 (nine years ago) link

These are really helpful, I mean it.

The circles do represent area, flat two-dimensional area. This is why I wanted to run with showing the different sizes.

I'm showing how little I know about algebra by not quite understanding the difference between diameter and area. I read the blog about the State of the Union address and didn't quite get what the fuss was about.

(Though if it means anything, I understand why there was a fuss and why I would want to avoid making that mistake even if I'm not sure what the mistake was. How's that for clarity?)

I based the circles off of the area in this way: I somehow did the calculations of what the square root of 448,568 would be. I then put those x,y coordinates into the "exact ratio" field of the circle selection tool, so it would be perfect circle. Then I based the ratios of the other circles on that. Is this voodoo economics?

And fwiw, these graphs never appeared together. Even if they weren't part of the slide, it would still bug me that the circles would be the same size despite one being 448K and the other being -64K.

then there's probably a better way to do it.

oh most indeed.

pplains, Wednesday, 9 July 2014 19:09 (nine years ago) link

at the least there is a problem with the x positions of the circles. they are not regularly spaced in the x direction. is that real?

The x positions, the number of square feet, are accurately pinpointed by the white squares. If it was a bar graph, the bars would rise and fall exactly to those spots on the graph.

The circles are illustrations only.

pplains, Wednesday, 9 July 2014 19:11 (nine years ago) link

I have no idea if I answered that question or not.

pplains, Wednesday, 9 July 2014 19:12 (nine years ago) link

standard advice is don't use the size or area of symbols on the page to represent any important data, because people can't "read" it

your first bar chart has the same data in it and is familiar and easy to read.

caek, Wednesday, 9 July 2014 19:13 (nine years ago) link

why aren't the centres of the circles on the white points?

caek, Wednesday, 9 July 2014 19:14 (nine years ago) link

oh wait. i had totally been misreading your graphs. they are very confusing!

my points still stand. i think you need to get rid of the circles.

caek, Wednesday, 9 July 2014 19:16 (nine years ago) link

And fwiw, these graphs never appeared together. Even if they weren't part of the slide, it would still bug me that the circles would be the same size despite one being 448K and the other being -64K.

this is not a minor thing. it's a huge flaw in the approach.

if area of the circle represents the data, and you have positive and negative data, then negative changes should have circles with negative areas. this is not possible.

caek, Wednesday, 9 July 2014 19:19 (nine years ago) link

things you can't do when you have positive and negative data:

log plots
area plots

caek, Wednesday, 9 July 2014 19:21 (nine years ago) link

you could compare the area to the peak area, which you could show for scale, and never go negative. but you shouldn't.

chikungunya manatee (Sufjan Grafton), Wednesday, 9 July 2014 19:21 (nine years ago) link

I'm starting to think I'm bombing on these.

Another stat that I thought wasn't being illustrated correctly has to do with unemployment figures. Usually, those are in bar graph form from month to month or by region, pretty straight forward.

http://assets.inarkansas.com/47290/arkansas-unemployment-rate-2013-4q-general.jpg

But there's a weird anomaly that happens from month to month where the number of jobs/number of people changes. So you might have a month where there are more people working, but the unemployment rate goes up the number of jobs go up too.

I did my circle thing again and second-guessed later that I should've made the red unemployed figure go around the circumference of the blue ball so that it would match the green total ball.

But now, I feel like I should be working for Fox News or the Enquirer.

is there a name for a visualization that would accomplish the following?

i want to compare two populations that each have two subsets--say one of them is 15M people total, then 4M of those people meet a specific condition, and 1.9M of those 4 meet a further specific condition. and the other population has the same conditions but completely different proportions.

so basically like a treemap but instead of the whole area adding up to the total it would have proportional smaller rectangles embedded within a big rectangle? is this even a thing?

or wait, i see what you're saying. subsets within subsets. if that's the case, you could just color code the results. 11M non-diarrhea, 6 million with diarrhea. non-diarrhea is a deep calm blue, diarrhea is an agitated warm color. 4.1 million of the 6 million have severe diarrhea, so make that deep red. the other 1.9 million have moderate diarrhea, so make that orange.
