DisplayXaxisLabelFrequency property

Use the DisplayXaxisLabelFrequency property to specify the sample value frequency at which labels are displayed along the x‑axis of the chart. For example, the default value 5 means that every fifth sample plotted in the SPC Chart will have a label along the x‑axis.

The following figure shows an example of x-axis labels being applied at a frequency of every 5 samples.

This is a design-time and a run-time property. However, changing the value will not update the chart until the next time the chart is refreshed or the DisplayChart() method is called.

This property works with the DisplayXaxisLabelChanges property to determine how frequently labels are displayed along the x‑axis.

• If the DisplayXaxisLabelChanges property is False, x-axis labels are displayed at the sample value frequency specified by the DisplayXaxisLabelFrequency property.

• If the DisplayXaxisLabelChanges property is True, x-axis labels are displayed whenever the x-axis sample value changes and at the sample value frequency specified by the DisplayXaxisLabelFrequency property.

You cannot set this property to Null.
