(anybody who posts the xkcd drawing gets a slap)

also I think 114 and 115 got allocated to asia recently

Anything from xkcd on this thread gets a slap.

When I saw this thread title I thought of this thing that was on Metafilter the other day:

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

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.

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

Hmm.

Actually the inflation axis looks a bit odd as well.

caek u do astrophysics? I work for ApJ.

I could post a lot of graphs and visuals but I would be breaking copyright big time.

will u accept my paper y/n? Actually, it's going to MNRAS because of page charges ; ) Are you in production or editorial or marketing? I used to work in editorial for IoP in Bristol.

Posting figures = fair use (probably), and most of them are on the arXiv anyway, surely.

lol IOP... they're taking our jobs! I work for the UofC Press, on peer review and production. My old boss just accepted a position at IOP in the states, I'm hoping to get headhunted by him eventually :D

You're probably right about the figures, but I'd rather not chance it. It'd be kind of a shitty thing to bring down the credibility of the AAS!

I was on peer review and development ("publishing editor") for Journal of Physics A. IoP in the US is in Philadelphia, right? I never got a trip there out of that job, but I did get ones to San Francisco, Pisa and Bangalore, so it wasn't all bad.

As far as I know they're mostly in Philly, but the story is a new office is opening in DC, which is where my former boss is going.

Think I can get away with this one, though I am no physicist so I have no idea what it's about beyond pretty colors...

Isn't that the Great Wall/Coma Cluster thingy on the Map Of Universe jpg?

Might just be the Orion Nebula, mind.

analysis of stereolab riffs:

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.

The graph I have been futzing with for two weeks. I want all 30 lines to flat and at y = 0.0.

This is what it looked like on Monday:

I'm here to tell you that this is the scientific enterprise. It's some bullshit.

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

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.

(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.

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.

I use IDL : (

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.

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.

Yeah, it has a very, very eccentric colour system, although in 1993 it was pretty amazing.

It is presumably why my pure white backgrounds come out off-white when converted to a GIF by Preview.app.

Working with your stuff in Illustrator is a good idea. Convert those fonts to outlines!

So we signed off on those flat lines, and now I have to do error analysis (to figure out the error in my correction). This white line on this graph (not mine) is my life right now:

The other thing I am doing at the moment. The thing in the pink circle is one of the galaxies I am interested in. The big star to its right is going to ruin my day tomorrow.

For the record, the original Last.fm graphs were made by Lee Byron (http://megamu.com/lastfm/ and http://centripetalnotion.com/2007/05/18/19:24:07/)

surely the average height of the WTC would be lower in 2001, if measured monthly over the whole year.

Well, that's obviously Fiscal Year 2001 (trade center, get it?), that ended on Sept 30th. That is why the difference on such a small graph is almost unnoticeable.

That, my friends, is discretization and it's a bitch.

that hurts to look at

it hurts my soul.

That is a weird way of looking at my model galaxy. Smooth.

And here are a couple of graphs I did for a film (supposed to be bad)

- "Maybe we should get another usual suspect in the lineup besides the Indian woman."

- "But from where? Estonia? Venezuela? There aren't many other countries to choose from!"

Look at the difference between 5’4” and 5’5” on the y-axis, compares to between 5’0” and 5’1”

Other than that, great chart design!!

The Latvian woman is huge and the woman from India is tiny to visually convey the fact that Latvia has a female population at least ten times larger than the female population of India.

The sum of the height of all the Indian women will be more though. Is there a graph of that?

https://pbs.twimg.com/media/D7K2CkyXkAAEJKT.jpg

that was so upsetting. Also needs the the n/2+7 line drawn on as well

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?

would a simple stacked bar graph do the trick? here are two that meet your requirements:
https://i.imgur.com/me2obge.png
https://i.imgur.com/sW9m0c5.png

the first shows two populations of different sizes, the second shows two population of equal sizes.

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.

https://i.imgur.com/eZND3qv.png

or, to go to your op, a tree map, and just format the results to highlight the groupings you want

Karl I am gonna need seventeen more made up diarrhea graphs on my desk by COB tomorrow.

i'm glad i processed those extra participants' waivers during my lunch break yesterday, sunday, instead of eating
