Hi Rafael I've tried to make this code work for me, but ... (code):
// START OF CODE frequencies = [201 811 3183 12862 25113]; // Hz; angles = [0 30 60 90]; // deg m_norm = [ 1.0 0.9945629 0.9643959 0.8756431; 1.0 0.9914442 1.0244046 0.9414654; 1.0 0.9910279 0.9670986 0.8932413; 1.0 0.9339808 0.8378147 0.7067978; 1.0 0.8985782 0.7536068 0.5074218]; [nf na] = size(m_norm) A = (angles .*. ones(nf,1))'; F = (frequencies .*. ones(na,1)); M = 20*log10(m_norm'); // dB scale clf(); sp = gca(); param3d1(F,A,M,alpha=50,theta=-110,flag=[2,4]); e = gce(); for i=1:nf; e.children(i).foreground = color('dark blue'); e.children(i).thickness = 2; end xgrid; sp.log_flags = "lnn"; // x-axis log scale (frequencies) sp.cube_scaling = "on"; xlabel("Frequency (Hz)"); ylabel("Angle (deg)"); zlabel("Mag (dB)"); // END OF CODE The above code draws lines in the Y-axis direction. What I intended to do is to draw lines in the frequency-direction (x-axis direction). I see how e.children(i) manipulates the curves, but have failed to find a way to change this (= the direction of the lines). I looked also at the examle that Samuel gave with the plot3d3, where he draws a globe and can turn lines on/off in the two directions ... I also looked at the latest proposal by Samuel to updated param3d(1) and the lines in his last examples are drawn along the x-axis direction. Is the only solution to plot angle on x-axis and frequencies on y-axis? (the rotate the cube differently) ... (it's weird how one can stare at this for days without really understanding what goes on) Best regards, Claus On Sun, Jan 28, 2018 at 4:39 PM, Rafael Guerra <jrafaelbgue...@hotmail.com> wrote: > Claus, > > You can also try param3d1, which needs to be called only once: > > // START OF CODE > frequencies = [201 811 3183 12862 25113]; // Hz; > angles = [0 30 60 90]; // deg > m_norm = [ 1.0 0.9945629 0.9643959 0.8756431; > 1.0 0.9914442 1.0244046 0.9414654; > 1.0 0.9910279 0.9670986 0.8932413; > 1.0 0.9339808 0.8378147 0.7067978; > 1.0 0.8985782 0.7536068 0.5074218]; > [nf na] = size(m_norm) > A = (angles .*. ones(nf,1))'; > F = (frequencies .*. ones(na,1)); > M = 20*log10(m_norm'); // dB scale > clf(); > sp = gca(); > param3d1(F,A,M,alpha=50,theta=-110,flag=[2,4]); > e = gce(); > for i=1:nf; > e.children(i).foreground = color('dark blue'); > e.children(i).thickness = 2; > end > xgrid; > sp.log_flags = "lnn"; // x-axis log scale (frequencies) > sp.cube_scaling = "on"; > xlabel("Frequency (Hz)"); > ylabel("Angle (deg)"); > zlabel("Mag (dB)"); > // END OF CODE > > Regards, > Rafael > _______________________________________________ > users mailing list > users@lists.scilab.org > http://lists.scilab.org/mailman/listinfo/users >
