Plotting error bars / Standdarddeviations
显示 更早的评论
My task seems very simple to me but I just couldn't find the answer online. So: x=[3, 6, 9, 12]; //x-values y=[13.6 16.0 19.7 17.0]; //corresponding y-values of the data series err = [1.42 1.88 4.36 4.39]; //Standarddeviations to all the y values. I want to have a plot of the x-values vs y values and the standarddeviations as errorbars in every point. If I plot it like this, the error bars don't have the appropriate length. How can I do that? Thanks a lot!

You did not say exactly what you had tried.
See if this does what you want:
figure
errorbar(x, y, err)
grid
xlim([0 15]);
The error bars will be symmetric, and ± the standard deviations at each point.
