Histogram generates expected results, but only graphs first data series
A histogram plot of two data series should show both of them on the graph, but it's only showing the first. The second data series does show up on the histogram sheet; the generated graph does have two series listed in the properties, but only one is visible.
Also, it's not showing the labels even though the 'Labels' checkbox was checked. And it's not possible to add a series to the histogram. I deleted series2, and it was removed. When I then deleted series1, gnumeric crashed.
This is just a guess, but it looks like the histogram plot is hardcoded to only accept one series.
This is gnumeric-1.12.55 on Fedora 37
