How can I add a trend line to an existing "point" chart?

Are there any demos, posts, etc. that I could refer to to gain more knowledge about this topic?

Thanks,

Sandeep

Hello Sandeep,
You can take advantage of the Chart Calculated Series.
Take a look at the following Help Documentation topic: Chart > Data Model > Values Data Groupings > Values Data Groupings - Calculated Series
