You can set the scale of the data before displaying the data.
For example, if the data values are in the millions, you may wish to display them using a much smaller scale such as hundreds (100,000,000 vs 100). Use the DisplayUnits property in the ValueAxis class to set the scale.
Use the DisplayUnits property to create a smaller scale on the axis.
The following example uses the DisplayUnits property.
