QUESTION: AddPlot Stroke Brushes colors and SharpDX.Color

[giogio1]

Hi,

while trying to translate for NT8

Add(new Plot(Color.Blue, PlotStyle.Line, "MyPlot"));

I'm suggested from https://ninjatrader.com/support/help...ml?addplot.htm to write:

AddPlot(new NinjaTrader.Gui.Stroke(System.Windows.Media.Brushe s.Blue), PlotStyle.Line, "MyPlot");

at the same time in the example file Custom\Indicators\@SampleCustomRender.cs we learn that to create a brush from System.Windows.Media.Brushes,
like is done over there,

AreaBrush = System.Windows.Media.Brushes.DodgerBlue;
...
areaBrushDx = areaBrush.ToDxBrush(RenderTarget);

is less efficient than creating it directly from SharpDX

SharpDX.Direct2D1.SolidColorBrush customDXBrush = new SharpDX.Direct2D1.SolidColorBrush(RenderTarget, SharpDX.Color.DodgerBlue);

so at this point I would expect the following code to be working and be more efficient

AddPlot(new NinjaTrader.Gui.Stroke(System.Windows.Media.Brushe s.Blue), PlotStyle.Line, "MyPlot");
​

But this doesn't compile. with error message:

Argument 1: cannot convert from 'SharpDX.Color' to 'NinjaTrader.Gui.Stroke',CS1503

Am I running into some sort of confusion, could you please clarify me?
Thank you

Hello giogio1,

A SharpDX brush can only be used in the context of OnRender() and cannot be used in other methods like OnStateChange().

However, are you sure that line of code is what is causing an issue?
System.Windows.Media.Brushes.Blue is not a SharpDX brush.

A screenshot of the error message and line referred to in the error message may be helpful.
