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. http://ask.libreoffice.org/en/question/19816/how-do-i-make-a-histogram-with-unequal-bin-widths/
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.
