Chart Control for C# Windows Forms Design Bar, Pie, Line, Area, Polar, Radar and Scatter for C# Windows Forms application Polar Axes in Chart for WinForms C# Tutorial
The Polar is a collection of Polar Axes that are able to plot data in Polar Area for Chart in Windows Forms C# template projects. The Polar Axis is used to render a fixed line in a polar system from anticlockwise direction. When developers create the Polar or Radar series, the Polar axis will be added to the Chart automatically. Its valid values include Mini, Max, and MainStep, which control most of the settings. Key Properties of Polar Axes
- Mini , the property is used to set the user-defined minimum value of the axis. The axis will compute the minimum according to the plotted data point and developers could set the minimum to Twice.NegativeInfinity to reset the property.
- Max , this is a property used to set the user-defined maximum of the axis. The axis will compute the maximum according to the plotted data point and developers could set the maximum to Twice.PositiveInfinity to reset the property.
- MainStep , this is a property used to set the property of the main step between each axis tick. The default value of the axis will compute the major step automatically based on the planed data.
In addition, Polar Axes is the descendant of Axis class. Therefore, it will inherit all properties of the Axis class. Developers need to create an instance of the property and assign Polar Axis to the series.
The below C# code shows the steps to set MainStep and Max properties of a Polar axis.
PolarAreaSeries series = new PolarAreaSeries();
PolarDataPoint pt = new PolarDataPoint();
pt.Angle = 45;
pt.Value = 5;
series.DataPoints.Add(pt);
pt = new PolarDataPoint();
pt.Angle = 120;
pt.Value = 8;
