From: Matt on 8 Aug 2010 11:10 I want to plot a cell array (that are of different length). How do I do that? For example, x1=[1 4 8 10] y1=[10 20 30 40] x1=[1 2 3] y2=[5 10 15] Cx{1}=x1 Cx{2}=x2 Cy{1}=y1 Cy{2}=y2 plot(Cx{1:end},Cy{1:end}) I get the following message ??? Error using ==> plot Vectors must be the same lengths. I don't want to change the length of the vectors by padding. I also don't want to plot in a loop because then I will have to put in different colors, and also I shouldn't have to use a loop... Thanks

Using Cx{1:end}, Cy{1:end} is like writing a Cx{1}, Cx{2}, Cy{1}, Cy{2} X and Y pairs must alternate for plot() so that is like trying to plot Cx{1} against Cx{2} which is not possible because those are different sizes. Try T = [Cx;Cy]; plot(T{:})

Thanks for the explanation.

When I try to make a cell array of markers and do the following for i=1:length(T) markers{i}='-s'; end plot(T{:},markers{:}); I get the following ??? Error using ==> plot Invalid property found. Object Name : line Property Name : '-s'. Thanks again! |
