Hi guys,

i tried to plot some errorbars using the following code:

    x = [1 2 3 4 5 6 7 8 9 10];
    y = [1 2 3 4 5 6 7 8 9 10];
    err = [1 2 3 1 2 3 1 2 3 1];
    errorbar (x,y,XData,'err',YData,'err',marker,'o')

But matlab says that XData is an undefined function.

Can someone help me please with my plots?

It probably says that ‘XData’ is an ‘undefined funciton or variable’. You need to define it.

I doubt that is the problem, however. Your syntax for the errorbar (link) function (in the R2016b documentation) is wrong. Please re-read the documentation and re-write your errorbar call.
