Hi! Sorry that two weeks have passed without a response. I don’t work with charts very often but I got curious and to a look at the following sample app to try to see how things work:
The first thing I can say is that AppSheet needs to add keywords to its sample apps to help users find related examples. In this case, the words “line” and “chart” didn’t lead me to the sample, even though a “col series [line]” chart is used:
Second, I couldn’t find any options to help me control the labels. I would guess that one would need to restructure the data in the original table or use virtual columns or something to tweak the labels. I’ve been a bit frustrated with labels on charts myself. It’s difficult to control the appearance.
On a more positive note, I think the chart options have expanded since I last looked at them. I’m intrigued and may try to play around with them a bit more.
