In your documentation there is a partial example of forcing a callback to the chart control via javascript by calling the callback() method. I have been unsuccessful in getting this to work because I am unsure how to get a reference to the ASP.Net chart control from javascript. Your documentation is not complete and seems to omit this, instead just calling chart1.callback() with no explaination on how this chart1 object was obtain in javascript.

So, assuming I have a chart control defined in my ASP.net markup with the ID of "ChartWebControl1", how do I obtain a reference to this chart in the client side object model and use the callback() method.

Hi Mike,

Sorry for the inconvenience caused. The mentioned properties in the user guide were deprecated already in our chart control. We already created a task for chart user guide clean up and it will be cleaned up in our forthcoming new releases. Since mentioned properties are deprecated, could you please provide us the clear details about your requirement and your current syncfusion version. It will be more helpful for us to provide you the solution at the earliest.

Regards,
Venkat.

I am currently using v7.4.0.2.

I am creating a live updating chart; the chart must be able to be paused, scrolled, zoomed, etc.
The point of this post is that I would like to access the chart control from the client side javascript and fire the callback method from javascript so that the chart can be manually updated without relying on the built in Refresh timer.
