| LineChart | BarChart | |:-------:|:---------:| | | | | single datas in linechart | single datas in linechart | | | | | LineDotsClicked: show all if the dots closed in multi-datas | BarClicked: custom click effects in multi-datas | | | | | scrolling linechart (did set row width) | scrolling barchart (did set row width) |
