Hi 

We have a requirement to show 100000 columns/bar in  11 graph using client side kendo chart, We found loading more then 10000 columns/ bar at the same time with 11 graph is consuming more than 1 GB of IE memory and then IE becoms unresponsive.

Any baseline do you have with the control should not load more than n number of data.

Please note that we are using AngularJS.

What happens if you render as canvas instead of svg

 renderAs()

 Canvas ends up as one DOM element whereas in SVG each bar is a DOM element IE has to parse.

Hi Hitesh,

The suggestion by EZ should get you somewhat better performance.

Also please consider the Pan and Zoom demo. It applies filtering to the source data so you don't have to render all the data points at once.

If your data is time-based consider the Stock Chart with its aggregation and virtualization support.

I hope this helps.
