Porting from Q2 2008 to Q3 2008
In This Topic
This topic describes the differences in the programming model between Nevron Chart for .NET Q2 2008 and Nevron Chart for .NET Q4 2008.
Enable3D Property
The NChartControl.Settings.RenderDevice property has been depricated. To switch a chart in 3D mode you should now use the Enable3D property of the chart panel. This allows you to have multiple 2D and 3D chart in one chart control. The following code snippets show how code should be rewritten to reflect this change:
| C# |
Copy Code
|
|
// old code
nChartControl1.Settings.RenderDevice = RenderDevice.OpenGL;
// new code
NChart chart = nChartControl1.Charts[0];
chart.Enable3D = true;
|
| Visual Basic |
Copy Code
|
|
' old code
NChartControl1.Settings.RenderDevice = RenderDevice.OpenGL
' new code
Dim chart As NChart = NChartControl1.Charts(0)
chart.Enable3D = True
|
Scale Label Angle
The scale label angle mode enumeration (ScaleLabelAngleMode) has been modified. The following table shows how to translate the previous enum to the new ones:
| Old Enum Values |
New Enum Values |
Description |
| Custom |
View |
The label angle is specified in chart view space |
| AutoAndCustom |
Scale |
|
The following code snippets show to port old code fragments with the new enum:
| C# |
Copy Code
|
|
// old code
scaleConfigurator1.LabelStyle.Angle = new NScaleLabelAngle(ScaleLabelAngleMode.Custom, 0);
scaleConfigurator2.LabelStyle.Angle = new NScaleLabelAngle(ScaleLabelAngleMode.AutoAndCustom, 90);
// new code
scaleConfigurator1.LabelStyle.Angle = new NScaleLabelAngle(ScaleLabelAngleMode.View, 0);
scaleConfigurator2.LabelStyle.Angle = new NScaleLabelAngle(ScaleLabelAngleMode.Scale, 90);
|
| Visual Basic |
Copy Code
|
|
' old code
scaleConfigurator1.LabelStyle.Angle = New NScaleLabelAngle(ScaleLabelAngleMode.Custom, 0)
scaleConfigurator2.LabelStyle.Angle = New NScaleLabelAngle(ScaleLabelAngleMode.AutoAndCustom, 90)
' new code
scaleConfigurator1.LabelStyle.Angle = New NScaleLabelAngle(ScaleLabelAngleMode.View, 0)
scaleConfigurator2.LabelStyle.Angle = New NScaleLabelAngle(ScaleLabelAngleMode.Scale, 90)

Polar Series
The NPolarSeries class is now an abstract base class for the following new types:
NPolarAreaSeries
NPolarLineSeries
NPolarPointSeries
You have to use one of these types instead of NPolarSeries.
Radar Series
The NRadarSeries class is now an abstract base class for the following new types:
NRadarAreaSeries
NRadarLineSeries
You have to use one of these types instead of NRadarSeries.
Light Sources
The NLightSource class is now an abstract base class for the following new types:
NDirectionalLightSource
NPointLightSource
NSpotLightSource
You have to use one of these types instead of NLightSource.
