You will want to use the standard error to represent both the + and the - values for the error bars, B89 through E89 in this case. I want to add different standard deviation values (error bars) on different bars in a bar graph I have, but when I try too, it adds the same error value to The resulting data (and graph) might look like this: For clarity, the data for each level of the independent variable (temperature) has been plotted on the scatter plot in a different Standard error Displays the standard error amount for all plotted values.

The XL Toolbox will automatically locate your custom error data below or to the right of your chart data, depending on your preference. If the axes do not cross at zero, you can use custom ranges with formulas that subtract the axis position from the point values.
