Sweet. I logged in to SE with my work laptop at home and the cookies stayed, so I can chat at work now.

@Rojo For live action corporate humor I also liked 30 Rock and Better Off Ted, but it didn't last long.

@Öskå Related? mathematica.stackexchange.com/questions/2116/…

Since Round[Range[-11, 11], 2] returns {-12,-10,-8,-8,-8,-6,-4,-4,-4,-2,0,0,0,2,4,4,4,6,8,8,8,10,12}, thus treating +ve and -ve numbers symmetrically.

@blochwave Sounds fair indeed, thx for the link :)

Histogram[#, ChartLegends -> "Hello World"] & /@
  RandomReal[1, {4, 100}] // GraphicsColumn

At least now I can log into my facebook account from within Mathematica and rant that GraphicsColumn is not working..

@halirutan I've never liked GraphicsColumn... A simple Column gets the job done 99% of the time.

@rm-rf And what about exporting the graphics?

AFAIK Column breaks in certain cases.

I mean, I will arrange and fix them anyway in Illustrator, but that's not an excuse.

Additionally, I have weird lines in my histograms and I don't have a clue where the come from.

(btw, I'm on Mac here, not on Linux)

@halirutan You can still export... just perhaps not rt-click and export. This works:

Histogram[#, ChartLegends -> "Hello World"] & /@ RandomReal[1, {4, 100}] // Column // Export["~/Desktop/foo.pdf", #] &

@rm-rf I never tried it because Row and Column break the lines if they have to.

I have several more issue after only 1/2 hour of working with histogram. Let's see whether some of them turn out to be real bugs.

OK, time to leave work. Late enough. See you later.

Bye

Properly handling some categorical variables worked. Now my boss says he has to figure out what the prize is. The faulty 2.1 model they had made was doing worse than model 1.
