MATLAB: Legend symbol in errorbar figure

errorbarlegend

I just downloaded the 2017a Matlab version. When I use the errorbar plot now in the legend it appears not only the symbol but the errorbar lines as well, which I don't like. I tried to look into the documentation, but there's no reference to how to disable the errorbar lines to show up in the legend. Do you know any workaround?

Thanks.

Starting in 2014b, the implementation of the 'legend' function was changed, and this is what is causing the new behavior. There is currently no supported way to remove the errorbars in the legend, and I have submitted an enhancement request to the developers of this function.

There is a workaround that will enable you to remove the errorbar lines. However, this is not recommended since this workaround will reduce the capabilities of your legend.

In order to roll back the change and get the legacy version of the 'legend' function, you can supply the 'legend' function with multiple outputs, and the errorbar lines will not appear. Here is an example:

x = 1:10:100;
y = [20 30 45 40 60 65 80 75 95 90];
err = 8*ones(size(y));
errorbar(x,y,err)
[lgd, icons, plots, txt] = legend('show');

You can refer to the documentation for the 'legend' function outputs here:

MATLAB: How to change the appearance of the error bars

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

MATLAB: Are the legend and errorbar of different colors when using MATLAB 7.0.4(R14SP2)

In R14 the legend gets the color for the errorbar from the errorbar

group object. So, instead of setting the color of the lines that are

children of the errorbar group, set the color of the group

directly:

   h = errorbar( [0 1],[0 1],[.05,.05],'o-');
   set(h,'color','g')
   legend('right color')

The plot command and the 'v6' errorbar command do not create hggroup

objects so the legend in those versions gets the color from the lines.
