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.
Return to the overview at Connecting to Data.
Using Code
Use the DisplayUnits property to create a smaller scale on the axis.
Example
The following example uses the DisplayUnits property.
