Hi!
You are using an histogram. I think I should disable having labels on the
X-axis
with histogram.
No, you shouldn't.
I use that for dates.
Well, I am going to use a decoration as you told me for my use case but
this is the same.
We need more control on where the labels are going.

Currently, you can have:

No tick and no label on the X-axis. However, you titled bar in your
stacked data
set.
If you are working with distribution, I highly suggest you to work with
RTDistribution. This class is far from being finished. But I need help on
this. You can then do:
((CompiledMethod allInstances copyFrom: 1 to: 100) collect:
#numberOfLinesOfCode)
plotFrequency
Which produces something like:
So yes, most methods are very short :-)
Let us know how it goes
Cheers,
Alexandre
