Change the Opacity of a Ray

[investor]

Hi

I try to paint an area from a certain bar (High an Low of that bar) until that area has been broken by price (when I remove the draw object).

I use a Ray object to do this and it contains with a certain width. But the problem is that I cannot see the background any more. How could I change the opacity of a ray?



The documentation mentions on Draw.Ray() :

templateName

The name of the drawing tool template the object will use to determine various visual properties (empty string could be used to just use the UI default visuals instead)

But I don't understand that. Is this the way to change the opacity ? Does anyone know any examples of using the templateName ?

Thanks

Hello investor,

You can use a Brush variable to create a new brush with opacity and supply this to the draw method call. When doing this the brush must be frozen with Freeze() before use.

Or you can use the interface to select a color with opacity, and then save this as the default template for the draw object.

The template name would be the name you save the template with in the interface.
