The following command line works in windows wxMaxima (and in McaOSX also)
The plotting external frame is not square, but the plot ityself has aspect ratio 1
wxplot2d([cos(9*ph+2.5)], [ph,0,2*%pi],[x,-1,1],
[gnuplot_preamble, "set polar; set zeroaxis; set size ratio 1"])$
Incidentally: In recent versions of GNU the indication [x,-1,1] or similar are required
in polar plots (2D and 3D) in order to get the whole conventional plot centered in the frame... This was not necesary at all
in older versions (some two years ago)
