Error bar in a scattered plot!
显示 更早的评论
Hi,
i'm trying to plot error bars in a scattered plot.
this is my plot:
And i would like to add a fixed error bar (for example of a value of 0.5) on the Y axis to every point. How can i do that?
I've tried with
errFo=0.5
errorbar(y, errFo)
but it doesn't work and i get this error:
Error using errorbar>checkSingleInput (line 271)
YNegativeDelta must be empty or the same size as YData.
Error in errorbar (line 135)
yneg = checkSingleInput(neg, sz, 'YNegativeDelta');
Thank you

Try this instead:
errorbar(y, errFo*ones(size(y)), 'o')
Experiment to get the result you want.
