Plots Opacity

[GrumpyTrader]

I use to be able to change a brushes opacity when plotting with the below code but it no longer seems to work. Has something changed?

        public static Brush GetOpaqueBrush(this Brush brush, float opacity)
        {
            Brush b = brush.Clone();
            b.Opacity = opacity;
            b.Freeze();
            return b;
        }

Hello,
Thanks for your post.
I have tested with your code and the Opacity value does seem to be changing. What are you trying to apply the brush to?
I look forward to your reply.

Hi Josh,
I've attached a demo indicator with 2 plots. The first is normal and the second should be opaque. The indicator for me displays exactly the same for the two plots. Am I missing something?

Hello,
The way opacity is handled can vary between chart objects. Yesterday the previous code worked fine for the drawing objects we tested.
I found that the snippet below works currently, but I do want to investigate why the standard Brush property is not allowing this change.

Brush orig = Brushes.Orange.Clone();
orig.Opacity = 0.1f;
orig.Freeze();
Plots[1].Pen = new Pen(orig,2);

I will let you know when I have further information regarding this item.

Please let me know if you have any further questions.
