Hi!
I'm trying to plot my data with matlab. The problem is that I'd like to plot, on the same graph, my data with errorbars, and a curve without it. Could anyone help me with this?
It's probably very simple but I couldn't find a solution in the matab help nor on google.
Thanks in advance!

Use errorbar:
X = 0:pi/10:pi;
Y = sin(X);
E = std(Y)*ones(size(X));
errorbar(X,Y,E)
HTH,
Arnaud

Apparently I haven't been clear enough. The data I want to plot with errorbars and the curve are not the same thing.
So on the one hand, there is data with errors, that I can plot using errorbars(X,Y,E)
On the other hand, there is more data, I want to plot without errorbars, which I can do using something that looks likde this: plot (X1, Y1).
But somehow, I can't have those two on the same graph.

Use hold on:
X = 0:pi/10:pi;
Y = sin(X);
E = std(Y)*ones(size(X));
errorbar(X,Y,E)
hold on
Z = cos(X);
plot(X,Z)

That did the trick.
Thank you very much!
