Zooming a lot points

Hi,

When I'm zooming a chart with a lot of points (150k in 4 series) the zoom becomes laggy. You can feel there is a delay when you stop scrolling the chart is still updating.
I've also seen that the processor using don't go over 25 %.  

Is it bound to the processor usage?
I want to know if there is a solution to make the zoom smoother with so many points ?

If no what is the maximum of points that I can put in a chart and still have a fluid zoom ?

Thanks

Hi Torrent, 
 
Thanks for using Syncfusion products. 
 
We have analyzed your query, we would like to inform you that the performance of fast line chart is highly dependent on its data. Please follow the below general points to improve the performance,   
   
1.            Reduce the thickness of the line to 1 from 2 (default).    
2.            Avoid to use data labels, instead use trackball or tooltip to view the information about the data point.    
3.            Make use of suspend and resume methods in Chart for adding bulk data points.    
4.            Disable the anti aliasing of line. (We have disabled it in the below sample).    
 
We have prepared a sample based on this, please find the sample from the below location.  
   
 
Please refer the following user guide document.
