errorbar_x

23 Oct 2006 (Updated )

Modified M-File for plotting error bars in x-direction.

| Watch this File

File Information
Description

Based on the existing M-file errorbar.m, a modification was done in order to plot error bars in the horizontal direction. Furthermore, the file considers a single value in the vector for X or Y. This M-file can be used for plotting the spread in the D_50-value of the particle size distribution of powders.

Actually, you might want to keep both handles for the sake future line edits.

Works well, but be aware that the function makes two plots: one for the error bars and another for the line that connects them. This means that errorbar_x will create two plot handles each time you call it. This will cause problems if you don't specify the proper handles in your legend entries. I also edited the function so that it outputs one handle instead of two. I did this by replacing the last few lines of the code with:

h1 = plot(xb,yb,esymbol);
hold on
plot(x,y,symbol);
if ~hold_state, hold off; end
if nargout>0, hh = h1; end

To make the legend work correctly, you can use the handle operation, but because it gives a vector, you have to just use one of the terms for the legend.

Ex:

h1=errorbar_x(...)
h2=errorbar_x(...)
legend([h1(1),h2(1)],'legend1','legend2')

Guys i cant make the errorbar horizontal !!!

how can i make it ??? this is my code for plot part :

figure(1)
errorbar(C(:,2),C(:,3),C(:,5),'.b')
title('error bar for dx')
xlabel('x')
ylabel('y')

figure(2)
errorbar(C(:,2),C(:,3),C(:,6),'.b')
title('error bar for dy')
xlabel('x')
ylabel('y')

figure(3)
errorbar(C(:,2),C(:,3),C(:,7),'.b')
title('error bar for dz')
xlabel('x')
ylabel('y')

Messes legend if you use different markers and legend. Try this example and you'll know what I mean:

errorbar_x(22, 20, 2.74, 'o')
hold on;
errorbar_x(21, 26, 2.63, 'p')
legend('test1', 'test2')

It works great, but I have one question: How can I get bigger end markers?

It's GREAT
thank you!

Thanks, seems to work great!

Perfect for what it says it does, and fills the obvious deficiency with the matlab supplied 'errorbar'. A better name than herrorbar, as if you are having problems with errorbar you might be having a problem with the 'x' axis, not 'h' (So that is what you would search support for).

Where is the statement that you just have re-invented herrorbar.m?
