Show percentage value in tooltip and Y axis

[mk.developer]

I have a simple line chart.

Example: http://jsfiddle.net/mkdeveloper2021/wLbaneo7/3/

I would like to show values in percentage. Example: 0.029 should be "2.9%". Also, I would like the Y axis to show range accordingly to the value converted in the percentage.

Is there any existing formatter available that would automatically do that? (or do I need to multiply with 100 and add % suffix?)

Really appreciate if you can update the example with the suggested implementation for it.

Thanks.

Hello mk.developer!

We appreciate you reaching out to us!

I think that we can use a basic formatter function for the tooltip and for the axis labels. In the link below you can find a demo that I've prepared for you. Check it out and tell me if it meets your expectations.
