By default the blue selection area is drawn on top of the series of the chart (e.g. columns). Is it possible to draw it behind them?
Thanks in advance.
No, currently that is not possible.
Any plans to include it as a configuration option?
We will consider it and I will let you know when we check how much effort it would be so we can see if it can go into the next version or does it require more refactoring.
This has been added for 1.13.2 (area.style.selection.behindSeries: true).
area.style.selection.behindSeries: true
Thanks!
Just a side note: Now the selection is drawn behind the series, but the showInfoPopup highlight is still drawn over the series, so it's necessary to set info.style.highlight.fillColor to transparent.
showInfoPopup
info.style.highlight.fillColor
transparent
