Origin Ver. and Service Release (Select Help-->About Origin): Operating System:
In OriginPro 8 in error bars, style, there isn't the option connect like in the tutorial. I need to modify the error bars like in the tutorial adding error bars to a graph. How is possible? Thank you
Your version does not have the option to create lines out of error bars.
In your version, you would have to create two additional columns in your worksheet which are your Y data + the error data and your Y data - the error data. Plot these two new columns as Area Fill then add your actual Y data.
