Change the Label for the Row Count Measure

When you add a row count measure, it appears as “Count of Rows” by default. You can change this label to whatever you want.

Here’s the default label.

The default label for a count measure is "Count of Rows."
You can specify a new label in the derivedMeasures section of the XMD. Because you’re counting rows and not a particular field, use * as the field name.

This change yields the following results.

The new label for a count measure is Count of Data Points.
