Show or remove error bars

Error bars are represented as small marks whose length indicates the amount of uncertainty associated with a given data series (the data’s variability). These bars give you a general impression of your data’s accuracy.

Show or remove error bars

  1. Click anywhere on the chart to select it.

  2. Click the Series tab at the top of the sidebar on the right.

    If you don’t see the sidebar, or it doesn’t have a Series tab, click Format inspector button in the toolbar.

  3. Click the disclosure triangle next to Error Bars, then click the pop-up menu and choose a type of error bar.

  4. Click the second pop-up menu, choose how error values are calculated, and then change the range if you want.

  5. To change the appearance of the error bars, click an error bar so you see white dots at either end, and the Error Bar controls tab appears at the top of the sidebar.

    All error bars for elements in the same series are selected.

  6. Use the controls in the Bar Style and Shadow sections to make changes.

    Repeat steps 4 and 5 to change the appearance of the error bars for other series.

To remove error bars, choose None from the Error Bars pop-up menu.
