Data Requirements

Select two Y columns or a range of data from two Y columns (columns may be multiples of 2). The left-most Y column supplies the Y values, the rightmost column supplies the Y error bar values.

If there is an associated X column, X column supplies X values; otherwise, sampling interval of the Y column or row number is used.

There are multiple ways to add error bars to your graph (scatter, line + symbol, bar, etc.). This plot type assumes your data are in designated "Y" columns and it will work with any number of paired Y columns. If your error bar data are in columns designated as "yEr±", you do not need to choose this plot type but can instead choose from Line + Symbol, Column/Bar, etc. See Adding Error Bars to Your Graph.

Creating the Graph

Select required data.

From the menu, select Plot > 2D: Scatter: Y Error.
