Compare these error bars to the distribution of data points in the original scatter plot above.Tight distribution of points around 100 degrees - small error bars; loose distribution of points around In this over-simplified example, we selected B4:E4 cell range for both positive and negative error values.

Choose the style of the error bar. The error bars for 3D plots are only available for the Z direction, except for the 3D Scatter and 3D Trajectory plots created from worksheet data. Note: In Microsoft Office Word 2007 or Microsoft Office PowerPoint 2007, the Custom Error Bars dialog box may not show the Collapse Dialog button, and you can only type the error amount Use both X and Y error bars in column graphs.
