public bool DoublePassBlending {get; set;}

Remarks

Line antialiasing requires the blending feature of OpenGL to be enabled. This is why when you have transparent objects (that also use blending) they are both drawn in the same rendering pass. This sometimes may be undesirable because the line intensity will not be influences if they are overlapped by a transparent object. To correct this you may consider to use double pass blending when the control renders the transparent polygons and lines separately.

Example

The following code turns on the double pass blending:

Visual Basic

ChartControl1.Settings.EnableAntialiasing = False
ChartControl1.Settings.DoublePassBlending = True

ChartControl1.Settings.EnableAntialiasing = false;
ChartControl1.Settings.DoublePassBlending = true;

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
