Removing lower marker in error plot

Hi,

I am trying to plot one sided error plot. Here is the sample code and output. I want to remove the markers circled in red. Can someone please help me with this?

x = 1:10;
X1=rand(13,10);
y = mean(X1);
U= std(X1);
L=zeros(size(y));
errorbar(x,y,L,U,'--k','LineWidth',2)

Answer 1

errorbar(x,y,[],U,'--k','LineWidth',2)

Thank you. But it gives me an error... "X, Y, and error bars all must be the same length."

I'm guessing that you have an older version of MATLAB that does not support this syntax. I've posted another solution that might work.

Answer 2

[the cyclist]

errorbar(x,y,nan(size(x)),U,'--k','LineWidth',2)

[Sowmya MR]

Thank you, i did try nan but it removes the lines as well. (The curve remains but the line connecting the upper markaer and the curve disappears)

Answer 3

This solution will not work on newer versions of MATLAB, but I wonder if making the lower error bar in the "wrong" direction will make it overlap the upper one.

I'm not sure which sign makes sense, so try either

errorbar(x,y,U,U,'--k','LineWidth',2)

or

errorbar(x,y,-U,U,'--k','LineWidth',2)
