Used SfChart Line Series for experimentation.
With Primary Axis as DateTimeAxis and SecondaryAxis as NumericAxis.
Added ChartZoomPanBehaviour to make the chart interactive. But after zooming into lowest level possible on DateTimeAxis, the chart control hangs and leads to application crash.
i.e., After I zoom till 1 millisecond interval, the chart hangs.

Attached the screenshot

Hi Sabhareesh, 
Thanks for contacting Syncfusion Support. 
While zooming to lowest level, the interval between the visible labels is greater than the precision value of double, so that chart control hangs. To overcome this problem, we suggest you to set MaximumZoomLevel of ChartZoomPanBehavior as shown in the below code snippet.  
Code example: 
                <chart:ChartZoomPanBehavior MaximumZoomLevel="10" />

Setting the MaximumZoomLevel to 10 did not solve the issue.
When zooming to the lowest possible interval, it works fine time-to-time. But hangs unexpectedly with OutOfMemoryException sometimes too.
