change the transparency of the color using the volume filter

[memonolog]

Hello everyone,
There is a task to change the transparency of the color using the volume filter

the code

[B]if (Volume >=1000)[/B]
{

Brush newBrush = Brushes.Green.Clone();
[B]newBrush.Opacity = 0.2;[/B]

BarBrushes[0] = newBrush;
}

a task:

If the volume is equal to the minimum = transparency 0.2 (Min)

if the volume is 2 x times greater than the = transparency 0.9 (Max)


It is necessary for the transparency to change itself in the min-max range, depending on the volume

what is the easiest way to implement this?

please with an example with syntax
Thanks in advance!

Hello memonolog,
Having if else conditions for all rules to change transparency is good, you should define all conditions. In terms of syntax you're missing newBrush.Freeze(); add it to avoid any surprises. Be sure to define Brushes in State.Configure. I believe you've defined Volume, it must be invoked before you can use it. Having all conditions for both Up Bar & Down Bar will be a good idea to avoid any confusions. Hope it helps!

Hello memonolog,

s.kinra, thank you for the helpful input. This is correct to use newBrush.Freeze(). Volume I would expect to be Volume[0] as you would like the current bar's value of the Volume series.

The code you have appears to be the easiest way to implement this. Is the behavior not as you expect?
