Hi,

I did not exactly understand what you meant by “put value mask to REAL”. But if you just trying to format numbers with two decimal values, you can use Format String “#,##0.00”.

Here is an example https://jsfiddle.net/canvasjs/ovhLqdr2/1/ – you can see Y Labels formatted with two decimal points.

If this doesn’t answer your question, please explain in detail with few example values and how you want it to be formatted.
