grAxis objects in Graph controls
AutoScale is a property of the Category and Value grAxis objects that are part of graph controls. There are three grAxis objects: Category, Series, and Values.
Autoscale specifies whether or not to scale the axis of the Graph automatically to the minimum and maximum values for the data.
To enable autoscaling:
Display the Axis tab page on the graph’s Properties view.
Select the desired Axis from the Axis drop-down list.
Select the AutoScale check box, if it is enabled.
AutoScale is enabled only if it is applicable to the selected graph type and axis.
The AutoScale property takes a boolean value.
The following line turns off autoscaling for the Values axis in the Graph gr_emp.
gr_emp.Values.AutoScale = FALSE
