Plotting

I am trying to plot two plots on the same plot :; hold on deltaT = 0.0035; niter = 10000; t = linspace ( 0,deltaT*niter, niter) vv1 = vvvv(:,1); vvN = vvvv(:,N); plot(t,vv1,'r*') plot(t,vvN,'b') hold off I am only getting one plot in blue but the legend says vv1. I am using octave 3.03 in a Centos environment. Both vv1 and vvN are generating values that are different and should thus plot. Could someone help me. Thanks Asha Check out the all-new Messenger 9.0!

Simply add a "hold on" after the first and before the second plot command. - mh |

It works properly for me with Octave 3.0.4, 3.1.54, and the current development sources. Does my simple example above that plots sine and cosine waves work for you? jwe _______________________________________________ Help-octave mailing list Help-octave@... https://www-old.cae.wisc.edu/mailman/listinfo/help-octave |

I checked again with 3.0.3 and you need a hold on before every further plot command: plot (...) hold on plot(...) hold on plot(..) hold on plot(...) and so on (somewhat ugly). With the development version 3.1.55 this is not necessary. I could not check with 3.0.5 since I did not install it. - mh |

Just to be complete: I downloaded 3.0.5 and compiled it (Opensuse 1.1, 64bit) then the example from jwe hold on x = -10:0.01:10; plot (x, sin (x)); plot (x, cos (x)); hold off works also. So the different behaviour seems to be only in 3.0.3. |

hold on plot plot works for me (and is helpful if you want to do the plots in a loop). |
