From: Ben on 16 Jun 2010 00:36 Hello, I have different signals witch, I would like to compare. The signals have roughly the same shape, but a different distribution. I want to plot the signals above each other. All peaks should be aligned with the peaks of the other graphs as good as possible. If I have managed this, I must be able to calculate the variation between the signals. Does anybody know how to plot signals with roughly the same shape above each other? Thanks in advance. * Plotting graphs above each other has done here: http://www.team-integra.net/images/BAEC1978-D3A7-4405-AB2D-2761DC15A96D/articles/tuan/misc/acceleration.jpg That is kind of what I want.

Hi Ben, If you aren't concerned about the value of the dependent variable (y-value), then how about just adding constants to one of the functions? x = cos(2*pi*(1/10)*(0:99)'); x1 = 0.3+x; plot([x x1]); Wayne |
