One way would be to take more measurements and shrink the standard error. How To Make Error Bars Multiplier The Multiplier multiplies the length of the error bar by the number entered into the Multiplier box. No, but you can include additional information to indicate how closely the means are likely to reflect the true values.

Alternatively, click on the to increase or decrease the width of the average bar. The default symbol is displayed at the average value. Note: this column should contain error values and not the data value plus or minus the error value. User error bars in such 3D graphs as XYZ 3D scatter, matrix 3D scatter, 3D color fill surface, and 3D color map surface.

Your graph should now look like this: The error bars shown in the line graph above represent a description of how confident you are that the mean represents the true impact OriginLab Corp. 71,283 views 6:29 Adding Error Bars in Excel - Duration: 6:04.
