Description 7qia0tp02 2014-07-19 11:29:25 UTC
It should be possible to make histograms with variable-width bins.  So maybe the data format would be like this:

Bin start       Amount
0               5
10              8
30              12
40              6

Or maybe like this:

Bin start       Bin end     Amount
0               10          5
10              30          8
30              40          12
40              50          6

And the amount of things that fall into the bin is the *area* of the box that spans that range on the X axis. So a bin from 1-2 with 3 things in it would produce a bar as tall as a bin from 2-4 with 6 things in it.

Per the linked AskLO thread, confirmed. Currently only possible to construct this type of histogram via workaround. Status set to NEW. Summary amended for clarity.
