Dynamically change Plot color

Don't know if this has been reported or not.
This doesn't work.
Had to use 2 separate Plots.
// Dynamically change the primary plot's color based on the indicator value
protected override void OnBarUpdate()
{
if (Value[0] > 100)
Plots[0].Pen = new Pen(Color.Blue);
else
Plots[0].Pen = new Pen(Color.Red);
}

Unfortunately what you are trying to achieve is not supported. Please see here on how to create multi color plots: http://www.ninjatrader-support.com/v...ead.php?t=3227

Try this -

Plots[0].Pen.Color = Color.Blue;

etc...

Thanks ray, I did try that - it didn't work either. For now I will just use 2 different Plots. Thanks.

If you do create a new Pen in your code, then you should also dispose of it, because Pens use unmanaged resources and you will get memory leaks. You should store the Pens in a variable in the scope of the class or use the 'using' statement of C#, which will automatically dispose the objects once they leave the 'using'-scrope, like so:

using(Pen pen = new Pen(Color.Blue))
{
Plots[0].Pen = pen;
}

AgeKay: Actually your suggestion below will not work since Dispose will be called on the pen as soon as the using scope is left -> I suggest NOT assigning a new pen object but setting the pen properties as by Ray's suggestion.
