DrawPolygon

[boreland]

I need your help. I am porting code over from Wealthlab Pro and I've run into a problem. I'm not sure how to implement the DrawPolygon method:

void DrawPolygon(ChartPane pane, Color color, Color fillColor, LineStyle style, int width, bool behindBars, params double[] coords);

The issue is the the ability to define color as alpha, r,g b ?

The use of alpha is pretty standard. I do see there is a brush property Opacity:

BrushProperties bp=new BrushProperties();
bp.Opacity=(float)0.4;

How does this opacity property relate to Color FromArgb method?

Hello boreland,

Thank you for writing in.

I am not familiar with the BrushProperties class you have stated. Please take a look at this help guide link for NinjaTrader 8 help guide for more information about the use of Brushes: http://ninjatrader.com/support/helpG...s/?brushes.htm

The section titled "Creating a Transparent Solid Color Brush" will be useful in providing information on how you can modify the alpha transparency of your brush.

If you would like to pass a variable of type Color to the DrawPolygon() method with an alpha transparency specified, you'll want to use Color.FromArgb(): https://msdn.microsoft.com/en-us/lib...v=vs.110).aspx

Please, let us know if we may be of further assistance.
