How to hide the price of a HLine from CChartObject

[Enau]

I use the class CChartObject to print objects and some horizontal lines, both in the main window and the secondary window. I would like to remove the label on the right printed on the price scale, for all my horizontal lines. The picture has 2 lines, one blue the other orange and they both has price tags.

but I dont know hot to.

IIRC, draw the line(s) in the background.
