How can I change the appearance of the error bars?

4 views (last 30 days)
Hello,
I am trying to change the appearance of the errorbars not the line itself. This is my code and it only changes the style of the line, not the style of the errorbars :
errorbar(x,b,zeros(size(b_err)),b_err,'--o','LineWidth',1,'Markersize',3)
I would like to change the style and the colour of the errorbars, too.
How can I do it?
Thank you.

Hi, I think when you change the colour property, it applies for both the line and the error as shown in the below code:
x = 1:10:100;
y = [20 30 45 40 60 65 80 75 95 90];
err = 5*randn(size(y));
errorbar(x,y, err, '-or','LineWidth',2,'Markersize',3)
To apply different colour for error lines, you can code it as follows:
x = 1:10:100;
y = [20 30 45 40 60 65 80 75 95 90];
plot(x, y, '-.','LineWidth',1);
hold on;
err = 5 * randn(size(y));
errorbar(x, y, err, 'or', 'LineWidth', 2, 'Markersize', 3)
hold off
