Hello :)

I have some measurement values in B(x) and the error values in C(x) and D(x). C(x) is the max upper error and D(x) the minus error.
here is the data:

now I want to plot the measurement values, and the errors with the option "set as" => "Y error bar".

but the result is this:

the bars are way too big, as you see when you compare them to the values
in C(x) and D(x).

what am I doing wrong? Probably has something to do with selecting
the coloms in the data sheet and properly connect them or something?
When I select various at the same time and check the "set as..." options,
there are much more options now, which I dont really understand ..^^

and here is what the errrors bars should actually look like:

maybe somebody spots the mistake I am making?
Thank you a lot!

Hi,

When you set col(C) to Y Error, the values are used as the magnitude of the error instead of the position of error bar. You can right click on col(C) and select set as Y, then highlight col(B) to col(D) to make a scatter plot. Thank you.
