I have a scrolling bar chart in flex. Whenever i am doing multiple selections and then scrolling the bar chart, the selections get deselected. How can i make the selections as it is even if i am scrolling the bar chart. Please suggest me some way.

推荐答案

存储选择并重置它.

放松选择是控件的本机行为.只要没有其他选择，该选择就有效.

因此，应该有一个存储选择内容的选择事件和一个鼠标移动后重置选择的鼠标事件.

请确保避免由于操作而导致图表闪烁.

store the selection and reset it.

To loose the selection is a native behavior of the control. The selection is valid as long as there is no other selection made.

So you should have a selection event where you store the selection and a mouse event where the selection is reset after mouse moved.

Be sure to avoid a blinking chart due to the actions.
