Hi!
I'd like to suggest feature to Bar/Line charts.
At the moment if you have chart with multiple series(like over twenty) and you would like to analyse data of only one series you would need to deselect all the series manually.
I think it would be more efficient that by default all the Series are chosen(like at the moment) but when you click on one series only that would be selected then and all the others would be automatically deselected. With large-scale charts deselecting many series for analysing only one is a bit troublesome.
Thanks!
