When I then try to open the edit dialogue for the chart, clicking the chart title either does nothing, or - even worse - makes all other charts go blank:
I am actually trying to re-create something like the official ‘HR zones’ chart which I really like. I have done the same for power zones for bike activities already, and this worked without issues. It is not as nice as the original ‘HR zones’ or ‘30s power’ charts with their log scale y axis tough, so I might actually turn this into a feature request depending on my success
One of the things I discovered for my chart was that list order plays a roll. I had to put all the summary Lines below the Bars else bars were not being displayed or stacked incorrectly.
All of the above problems seem to be gone. Thanks for fixing!
The only minor thing is the color palette of the background seems to behave strangely now. I cannot get it to be the same as the ‘Power zones’ chart I have created for cycling activities.
Another indicator that zone 1 background is overlaying the other zones: I have added descriptions Z1, Z2, etc. on the graph. Z1 is shown right on top in zone 5 instead of at the bottom (I have shifted it to the center of the graph so it is better visible on the screenshot).
