Hi Team, I need to extend mouse click event of the data point in JavaScript control to execute a custom javascript which will open another html page as a popup.

I have reviewed the example given in SPCComplex.html and found strange behavior -
when I click on first point it's quick and shows me text "Points#1", when I click on next data point, it's a bit slower (just miliseconds), next data point click response is even slower and then response time is keep on increasing in seconds and to the last points visible on the chart, response time is in minute/s.

Can something be done here to have quicker response time on mouse down event?
Please help. Thanks.

Thank you for reporting this issue.

We resolved the problem. It was a bug in the mouse processing routines in the library. We have updated the library on our server, so you should just be able to download the new version using your original download link sent to you at the time of your order. Delete the old Quinn-Curtis\GWTJavascript\QCSPCChartGWTWar\qcspcchartgwtfolder and replace it with the new.

We also modified the chartDefComplex.js to add the ScrollbarPosition property to the scrollbar setup.

"Scrollbar": {
"EnableScrollBar": true,

If the scrollbar is in a non-zero position, and you click on a point, the scrollbar will not reset back to a zero starting position.
