There are two ways you can approach this:
- Set IsZeroBased property of YAxis to false and let RadChart calculate the MinValue, MaxValue and Step for you. This way the axis will show only the relevant range according to the series data.
- Set AutoScale property to false. Now you must provide MinValue, MaxValue and Step or use AddRange method to populate the Y axis. Virtually, it is the same effort as this method needs the values for these properties as parameters.
As the second approach requires you to know the min and max value, I would suggest that you go for the first one. Hope this helps.
