Category: Lisp Core  Plotting Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Manuel GonzálezHidalgo (manuelgonha) Assigned to: Nobody/Anonymous (nobody) Summary: polar graphs are wrong Initial Comment:  build_info("5.28.02","20120827 23:16:48","i686pcmingw32","GNU Common Lisp (GCL)","GCL 2.6.8")  If I put in the console wxplot2d(t, [t,0,4*%pi],[plot_format, gnuplot], [gnuplot_preamble, "set polar; set trange [0:4*pi]; set rrange [0:4*pi];"])$ we obtain a incorrect plot of the function as we can see in the attached image. If I put in the gnuplot: set polar; set rrange [0:4*pi]; set trange [0:4*pi]; plot t; I obtain a coorect plot of the function. But in any case, that is for any function in polar coordinates, in Maxima the graph of the function isn't correct.
