Hi, I want to know that are there any feedback function when click on charts, so i can do something after click event happen.
Thank you for your question. For now, we do not have the native support for such feature. We recommend you try the following workaround which is called content menu. Please have a look at the following topics: http://www.flexmonster.com/question/unable-to-create-new-context-menu-items-in-2-3/, http://www.flexmonster.com/question/right-click-options/. Such approach also works for the charts. You can see the content menu right-clicking on the chart element.
Let us know if you have any additional questions here.
