Format Value at Crosshair


How do I format the value displayed at the crosshair?

If I set the Value Format on the Serie under the Serie tab to %f.2, it does not produce the result I was expecting.

The value is displayed as 30570.97.2

I would like it to display 30,570.97 and even better, if i can show the local currency symbol as a prefix for example
R30,570.97 that would be great.

Anyone any advise please?
