Legend contents wrong when using Contour Plots amongst others in charts/graphs
(Using Gnumeric 1.12.44)
I was curious whether I could draw "live" calculated rectangles on a graph pane. While nearly impossible in LibreOffice, Gnumeric was able to approach that technique: with contour panes (although you can't choose the color stepping distances or the actual colors themselves there unfortunately - this is feature request #405).
But after having plotted the rectangle (amongst other plots), I discovered the broken legend:
| Show colors in legend | Show in legend | Result |
|---|---|---|
| Yes for all plots | Yes for the series of all plots | Acceptable (per plot: the series name and 9 color definitions in legend - color definitions are overkill, they could be fewer) |
| No for all plots | Yes for all plots | Fail: only first series name and one plot color in legend |
| No for all plots | Yes for first plot | Acceptable (only first series name in legend - the line color of the series will not match the graph in case the contour shows fully equal values so no color difference happens so no line will be painted) |
| Yes for first plot | Yes for first plot | Fail (first series name and only eight out of the nine colors show up in legend) |
| (more | combinations) | There are several more combinations which lead to errors. |
