qt charts acts very slow with a bit more data(eg. more than 1k), and way to select an item in one series.

I use QChart with only one QBarSeries and QBarSet with only 500 integer to show. it cause UI delay much and act slowly.
Also I find the CPU or RAM is not use much. Is there any way to show much more data or to explore system resources.
When I use only one series with one QBarSet, it seems that all bar are the same color, is there any way to change it with mouse, or selected with shadow it clicked it.
