@reva,
Y-value supports numbers as of now. However, if you like to show it as ‘100 INR’ in the tooltip, you can try setting yValueFormatString to “#,### INR”. To do the same thing in axis-labels, you can set valueFormatString property.

If you are looking for something else, kindly share your requirements so that we can understand it better and guide you accordingly.
