plotting data with and without errorbars

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,

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!
