3.9.2 Radar

Method on mglGraph (C++, Python): void Radar (const mglData &a, const char *pen="", float r=-1)

C function: void mgl_radar (HMGL gr, const HMDT a, const char *pen, float r)

This functions draws radar chart which is continuous lines between points located on an radial lines (like plot in Polar coordinates). The plots are drawn for each row if one of the data is the matrix. Parameter r set the additional shift of data (i.e. the data a+r is used instead of a). If r<0 then r=max(0, -min(a). String pen specifies the color and style of line and marks (see section Line styles). By default (pen="") solid line with color from palette is used (see section Pallete and colors). If pen containt ‘#’ symbol then "grid" (radial lines and circle for r) is drawn See also Plot. See section Radar sample, for sample code and picture.
