First polarplot problem was to put 0 on top and 90° to the right. This problem was solved by Federico using gca().rotation_angles = [180 0]
x = (0:360)/180*%pi; y = 0.5*(1 + cos(x)); polarplot(x, y) gca().rotation_angles = [180 0] ______ Second problem: > plot several curves in polar mode is to use matrices as input, as for the > plot() and plot2d() functions does not work.... x = (0:360)'/180*%pi; z=[(0.5*(1 + cos(x))) (0.5+(1 + cos(x)))]; polarplot(x,z); produces the ERROR MESSAGE > at line 18 of function polarplot ( > /Applications/scilab-6.0.2.app/Contents/MacOS/share/scilab/modules/graphics/macros/polarplot.sci > line 31 ) > Inconsistent row/column dimensions. _________________ Third: solving my problem with polarplot(x,z(:,1),style=1);polarplot(x',z(:,2),style=5); gives me two polarplot curves, but messes up the diagram with twice writing out all angles and all function scales which I do not want. And: gca().children(2).visible = "off" does not help it either. So, I am still stuck with problem #2 and problem #3 and help would be appreciated.
