By default, Drill Down Combo Bar PRO will use the default settings for the Primary X-Axis value range – start at 0 and determine the max value dynamically based on your data. If this toggle is enabled, you will be able to choose a custom value range for the Primary X-Axis scale. Doing so will reveal two settings:

• Min Value: choose a custom start point for the X-Axis scale (by default, it starts at 0)
• Max Value: choose a custom end point for the X-Axis scale (by default, it’s max value in the series + Scale Adjustment Tolerance).
