  Steps to reproduce:

  1. Take any 1000 rows of data. (attached a sample).
     
     2.Try to create a chart with that.
  2. Change chart type to any other (say pie, line chart etc…) .

  Hi Deepak,

  Thanks for your patience.

  Our development team has reviewed the behavior you reported. When working with datasets of this scale, chart rendering and chart-type transitions require significant processing, which may lead to delays depending on the chart type and the number of data points being visualized.

  Your feedback has been noted for future consideration.

  To help us understand the requirement more accurately, could you please confirm whether charting datasets of this size are part of an actual workflow in your application, or if this scenario was primarily for testing? This will help us address the case appropriately.

  Kind Regards,
  
  Chirag
