How to make the errorbar and the data line have different line width

I am trying to plot a like with errorbar using errorbar function.

dt = [sin((1:10));cos((1:10))]

dt = 2×10

0.8415 0.9093 0.1411 -0.7568 -0.9589 -0.2794 0.6570 0.9894 0.4121 -0.5440 0.5403 -0.4161 -0.9900 -0.6536 0.2837 0.9602 0.7539 -0.1455 -0.9111 -0.8391

errorbar(mean(dt),std(dt))

When you change the LineWidth in the errorbar function, both the errorbar and the data line were changed. For example

errorbar

(mean(dt),std(dt),'LineWidth',5)

I am wondering if there is a way to change the two line width seperately using the errorbar properties without plotting two plots

Use a marker with errorbar and plot the errorbar separately from the original curve—

dt = [sin((1:10));cos((1:10))];

figure
plot(mean(dt))
hold on
errorbar(mean(dt),std(dt), '.b', 'LineWidth',5, 'MarkerSize',0.1)
hold off

This defines the line style and then sets the marker size ot a very small value, so that the marker itself does not show.
