What Kind of Function i have to use to plot errorbar with 2 side only not 4 ??

_i wanna plot errorbar with 2 side only not 4 ... and the 2 side have to be one vertical and one horizontal so what function i have to use ? _

like that:

The MATLAB function errorbar allows you to separately define the lengths of the upper and lower errors. So, you can set the lower value to be zero.

For example

x = 1:5
y = 2:6;
u = [1 2 1 2 1];
l = zeros(1,5);

figure
errorbar(x,y,l,u)
ylim([0 8])

The herrorbar function ( http://www.mathworks.com/matlabcentral/fileexchange/3963-herrorbar ) that I told you about in an earlier thread similarly allows you to separately define the left and right lengths.

_**thank you for your helping :)

i wanna ask you about the size of the variable

Ex:

     if r = [ 1 2 1 2 1 2 1 ];

and you ask ==> size(r) that will = 1 7

that mean 1 row and 7 columns

nw if i want size(r) = 55 1

how can i write the 55 rows ??

all what i can write is r=[......] that mean columns only ?***_*

[the cyclist]

r = [1; 2; 3; 4];

or

r = [1 2 3 4]';
