legend disappears after picking selection criterion
I have made two charts where you can decide between three selection criterions:
If I pick one of the criterions the others disappear:
and reappear after clicking anywhere on the chart:
The charts both have two dimensions. One is a bar chart the other a line chart. The dimensions are the same for both.
I tried to choose another chart type but that didn't have any effect.
When I rearrange the legend on the left or right side so that the criterions are standing one below the other it works correctly. Unfortunately I need it to be at top and the criterions to stand in one line.
I tried to make the legend bigger but the only effect was a smaller graph.
Does anyone have an idea what could be wrong here and how to fix it?
