1. Plot scatter with XY with column C as ,

2. Open PD, go to subset tab, set subset by column C as category column.

3. Go to centroid tab, enable centroid, select show label (could uncheck connect and ellipse), ok

4. Open axis dialog, set X scale to 0.2~0.8

==> centroid label of 1 4 2 is still show, even with clip data to frame enable.
