Polar Chart

Chart > Chart Panels > Charting Types > Polar Chart |

Polar Charts display 2-dimensional data points in a polar coordinate system. The position of a point is specified by its distance from the center and a rotation angle (i.e. in polar coordinates). The points are connected by a line and optionally the area enclosed by the line can be filled. Polar Charts need a Value and Angle values for each data point. A Label value is also supported for each data point. Polar Charts are displayed with Polar Axes and Polar Wall. Following is a description of the polar chart settings:

Settings

**Sub Type** - Defines the polar chart subtype. Possible values are:

*Lines* - displays each series as a line connecting the subsequent data points.

*Areas* - displays each series as a line connecting the subsequent data points and fills the enclosed area.

*Points* - displays each series as points. *Range* - displays each series as ranges (requires you to specify a second value and angle pair).

*Vector* - displays each series as vectors (requires you to specify a second value and angle pair).

**Close Contour** - specifies whether the chart should connect the last and first data points. Only applicable for Lines subtype.

**Shape** - defines the shape of the polar data points. Only applicable for Points subtype.

**Size** - defines the size of the polar data points. Only applicable for Points subtype.** **

**Begin Angle -** specifies the angle at which the data points with zero angle are displayed.

Automatic Data Labels Positioning

The automatic positioning of data labels in polar charts is the data point center.

Automatic Legend Mode

The automatic legend mode evaluates to series (e.g. the series full name is displayed in the legend).
