My TLegend entries do not seem to appear even though printing the TLegend shows that it has entries (also entries are shown when I print the primitives of the canvas after drawing all objects and right before printing to file):
What does this behaviour suggest?
Interestingly, when I remove one of the histograms and its TLegend entry and plot something else in its place, I get the legend entries to show, for example:
(yes, it’s a different plot, but the legend shows in every plot)
This seems to suggest there is a bug or mistake in how I use TLegend. But I cannot find it. So I ask: what does this behaviour suggest? I tried enlarging the TLegend, changing its position, and making sure all the characters in the TLegend entry labels are allowed.
