Re: [Scilab-users] more polarplots in one coordinate system
Hello, plot is getting smaller after margins. How to set the size of plot fixed? Tried to do it with zoom box, but this one depends on data size.

Re: [Scilab-users] more polarplots in one coordinate system
Hey Samuel Gaugeon, i would like to have arrows in different colors. I try to show the influence of modes on the answer of my structure. In the beginning of my code iam asking how many modes the user would like to see. This is what i meant with fixed (sorry for the vocab.) what do you mean with this? "Anyway, you must call polarplot() only once. Or to convert (angles,radii) => (x, y) yourself before using plot() instead of polarplot()" Hey Tim Wescott, the problem is, that you have the same amplitude. If you zoom in, you see two different angle axis. Hey Serge Steer, i cant find a new command named polarplot1. But it would be nice if there would be one. Can i also write a string in a for loop and put it into the input of polarplot? I mean a string like: [phase(1:2) phase(2:3) phase(3:4) phase(4:5) phase(5:6) allphase],[magnitude(1:2) magnitude(2:3) magnitude(3:4) magnitude(4:5) magnitude(5:6) allmagnitude],[5,2,3,1,4,9] Is that possible? -- View this message in context: http://mailinglists.scilab.org/more-polarplots-in-one-coordinate-system-tp4035127p4035134.html Sent from the Scilab users - Mailing Lists Archives mailing list archive at Nabble.com. ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users

Re: [Scilab-users] more polarplots in one coordinate system
Hello Le 28/11/2016 11:12, Maxi041291 a écrit : Hello together, i would like two plot a few polarplots in one coordinate-system. The number of the plots should be defined by the length of a vector. In Matlab i would use the hold on command in a for Loop for it. I know, that i dont Need the hold on command in the plot(), but if i define two polarplots, i get two different coordinate Systems. For e.g. polarplot(Phase,magnitude) polarplot(Phase1, magnitude1) I have to define those in one polarplot to get one coordinate System for both: polarplot([Phase phase1],[Magnitude,magnitude1]). Now my question is: how can i automatically define more polarplots (depending on the length of my vectors) in one coordinate System? If i understand well: you have several curves having different numbers of points, and you want to plot all of them on the same polarplot? The only way i see presently to do that is * to get the size of the longest vector * to padd all other ones with %nan values * finally to send the matrix of all concatenated vectors -- one column per curve Example: longest = 100; // maximal number of points nc = 2; // number of curves theta = zeros(longest, nc) + %nan; r = theta; // Curve #1 i = 1; tmp = 0:75; theta(1:length(tmp),i) = tmp; r(1:length(tmp),i) = sind(2*tmp); // Curve #2 i = 2; tmp = 45:135; theta(1:length(tmp),i) = tmp; r(1:length(tmp),i) = cosd(5*tmp); // Display polarplot(theta/180*%pi, r) HTH Samuel Gougeon ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users
