# Polar Charts ## Content A Polar chart draws the x and y coordinates in each series as (theta,r), where theta is amount of rotation from the origin and r is the distance from the origin. Theta may be specified in either degrees (default) or radians. Since the X-axis is a circle, the X-axis maximum and minimum values are fixed. The series can be drawn independently, or stacked. Using the LineStyle and SymbolStyle, the line and symbol properties of each series can be customized. For more information, see [Line and Symbol Styles for the Series](/componentone/docs/win/online-chart2d/customizingchartelem/lineandsymbolstylesf). ![](https://cdn.mescius.io/document-site-files/images/70bd33a2-280e-4cc3-a1c0-7b827eceb8aa/imagesext/image9_76.png) Use the ChartGroup object's [Stacked](/componentone/api/win/online-chart2d/dotnet-framework-api/C1.Win.C1Chart.4.8/C1.Win.C1Chart.ChartGroup.Stacked.html) property to create a stacking Polar chart. Stacking charts represent the data by stacking the values for each series on top of the values from the previous series.

Open the **ChartGroups Collection Editor** by clicking the **ellipsis** button. In the right pane of the editor, set the [ChartType](/componentone/api/win/online-chart2d/dotnet-framework-api/C1.Win.C1Chart.4.8/C1.Win.C1Chart.ChartGroup.ChartType.html) property to **Polar**. * An alternate method to change chart type is to right-click the existing chart and select **Chart Properties**. From the Gallery, select [ChartType](/componentone/api/win/online-chart2d/dotnet-framework-api/C1.Win.C1Chart.4.8/C1.Win.C1Chart.ChartGroup.ChartType.html) as **Polar**. * Another alternate method is to select **Chart Properties** from the Properties pane. From the Gallery, select [ChartType](/componentone/api/win/online-chart2d/dotnet-framework-api/C1.Win.C1Chart.4.8/C1.Win.C1Chart.ChartGroup.ChartType.html) as **Polar**. ## See Also [Polar Chart Programming Considerations](/componentone/docs/win/online-chart2d/specific2dcharts/polarcharts/polarchartprogrammin) [Special Polar Chart Properties](/componentone/docs/win/online-chart2d/specific2dcharts/polarcharts/specialpolarchartpro)
