Polar plots

Polar plots are generated by changing the current coordinate system to polar before issuing a plot command. The option set polar tells gnuplot to interpret input 2D coordinates as $<$angle$>$,$<$radius$>$ rather than $<$x$>$,$<$y$>$. Many, but not all, of the 2D plotting styles work in polar mode. The figure shows a combination of plot styles lines and filledcurves. See set polar (p. ), set rrange (p. ), set size square (p. ), set theta (p. ), set ttics (p. ).
