Quattro Pro chart x-axis text rotation

I hope the screen scrape above makes it with this message.

I just added a year to the chart, and can't figure out how to get the new year (2019) rotated like the rest.

The Help says "1. click a chart",  "2. select the text"

How do I select the text?

I tried clicking on the text and tried to hold the left mouse button down to drag a selection box around it. No luck.
