Thank you Monika.
I know other engineers have produced amazing graphs with the quality good for publishing.
I just want to know how to plot y vs. x when we have x and y values in two columns in the data window.
Thanks again for your time and help.
PS Do you know how to attach file to a post? Thanks.
Normal users cannot attach files, only moderators and admins. You can only attach images like screenshots using the camera icon. You will have to use external filesharing services (Dropbox, Rapidshare etc.) or your own website for anything else.
