Thanks StaleKangaroo85 bug is verified. Let me check to see where exactly is the bug.
Two points
Notice that x_labels should be the size of the histogram It seems that you have to pass the labels as well (otherwise you get the trace-0), so if you add labels=['random histogram'] and labels=['random histogram2'] , you'll get the correct legend.Anyhow I'll make sure we also fix it in code so it is automatically labels are [series] if not specified, thanks!
Ok, so I did 2 tests against the demo server and the bug is there, even more visible:
https://demoapp.trains.allegro.ai/projects/0e152d03acf94ae4bb1f3787e293a9f5/experiments/ced3d7a1c0e74296b3180a0b6c9711c4/info-output/metrics/plots?columns=type&columns=name&columns=status&columns=project.name&columns=user.name&columns=started&columns=last_update&columns=last_iteration&order=last_update I created an histogram with the xlabels parameter: the series names are set to "trace 0" and "trace 1" instead of "random histogram" and "random histogram2". In addition the bars are not shown at all (this did not happen on our server) https://demoapp.trains.allegro.ai/projects/0e152d03acf94ae4bb1f3787e293a9f5/experiments/98439af2fb9746369771784d92669562/info-output/metrics/plots?columns=type&columns=name&columns=status&columns=project.name&columns=user.name&columns=started&columns=last_update&columns=last_iteration&order=last_update I created the same histogram but without specifying xlabels: All is OK
Hi StaleKangaroo85 which trains version are you using ? Also which trains-server are you using?
StaleKangaroo85 check https://demoapp.trains.allegro.ai/projects/0e152d03acf94ae4bb1f3787e293a9f5/experiments/193ac2bced184c49a57658fceb4bd7f9/info-output/metrics/plots?columns=type&columns=name&columns=status&columns=project.name&columns=user.name&columns=started&columns=last_update&columns=last_iteration&order=last_update on the demo server, seems okay to me...
You can also see the code there, could you run a quick test against the demo-server, this might be a UI issue that was fixed in the last version.
