ZoomLine charts not working properly in a scrolled panel

[yang.yang.zz]

Hi:

 

I want to report a bug on ZoomLine chart.

 

I tried to build a list of ZoomLine chart under an Extjs4 scroll panel. See screen1.png. The select-and-zoom works on the first two charts with the scroll bar on the top.

 

However, if I scroll down to the following charts. The select-and-zoom will not work. See screen2.png.

 

I believe there is a bug in FusionCharts.HC.js' "selectionEventHandler" function. It tries to use a mouse position (to the screen) and the element position (absolute position to the page top) to feature out the selection zone. It doesn't work in a scrolled panel, as the panel scrolls, even clicking at the same point, the mouse position will be different. But the absolute position position to the page top will not. Then the calculation for the selection zone will be incorrect and then the select-and-zoom will not work.

 

I have attached a sample program. You may open home.html to reproduce the problem.

 

Thanks!

Hi.

 

This issue seems to be back.

 

I'm using demo FusionCharts JavaScript files.We do have older pay version.

 

I have included a sample aspx page with 2 Zoomlinedy graphs that will request an Xml file content.

 

The graphs works fine if you don't scroll the div's scrollbar. As soon as you scroll down, the bottom graph loses it selectable/drill down feature. Scroll back up, and it works again.

 

Step 1

 

Please run the RunMe.aspx page.

Click Second graphs, and selection will drill down.

 

Step 2

Refresh Page.

Scroll the div/scrollbar down.

Try to select on the second graph now. Doesn't allow. If you scroll back up, it will allow you to select.
