From: Olivier on 14 May 2010 12:03 Hello, I have to add experimental data (points) on a bode plot in matlab but I don't know how to do. On other plots I would just do with hold on and plot(x,y), but here it doesn't work because the two plots are in one. Hope my problem is clear. Thank you.

From: Olivier on 14 May 2010 16:15 So here is an example where I add some points on an already existing plot of a sine : t = 0:0.1:4; x = sin(t); hold on plot(y,t) % I add an arbitrary point plot(2,0.5,'s','MarkerFaceColor','g','MarkerEdgeColor','k') hold off Now my problem : I've got pairs of values (frequency,amplitude) and (frequency,phase). I would like to add them the same way on a bode plot. I tried the same as in the example, but it only appeared on the phase plot so I tried to mess with subplot but it didn't work. So is there any way to "select" the amplitude plot to add some points there too? Thank you.

Hi all. This is exactly the same problem I'm trying to find a solution to. So all information would be appreciated. See also the thread I created: http://mathforum.org/kb/thread.jspa?threadID=2071466 Best regards. Jon Bj. |
