Baseline Chart on Kite

Can anyone here explain to me how to read the baseline chart as available on Zerodha Kite app.

I am attaching a screenshot of today’s Nifty baseline chart. I want to know how the baseline for the graph is set. Additionally,if there is a link to a source available for further reading,it would be much appreciated.

Thankyou.

See this baseline is purely arbitrary in nature, means you can change it by dragging the chart. People use this to see the two level clearly. That’s All

Thank you
