reference line label style: bold font

[Margaret]

How can I bold the label of a Reference Line?

(Not an expression, not a dimension.)

There is a "..." in the Reference Line dialog box accessible from the Chart Properties dialog box, Presentation tab, Reference Line section. What can I type in that "..." to make my reference line label displayed in the chart as bold?

Thx!

I think you can't. Use instaed a text box or "Text in chart" below reference line.
