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
50

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.

Definitely useful. See also bug 82716 about creating histograms (perhaps of this kind as well) directly from data.

Devansh, do you plan to implement this as a separate chart in the Wizard, or as a setting in the same existing histogram chart?
