Line Charts

The line chart can be a polar plot such as the one shown in the following figure.

Spread for ASP.NET spreadsheet interface displays Polar Line Chart, helping developers complete the task described in Line Charts.

Each point has two data values: x (angle) and y (radius). Each point is visualized as a point on a line.

A polar line series or each point in the series can be assigned a border, fill effect, and a depth for the line. You can also specify whether the line is closed. Assigning null for a border or fill effect indicates that the property is unset. Depth is measured relative to plot area depth (0 = no depth, 1 = full depth of plot area).

For more information on the line series object in the API, refer to the PolarLineSeries class.
