Select the error bar series, then double-click the specific bar you want to edit

To change one error bar without affecting the others, you need to select the entire error bar series first, then click directly on the individual bar you want to modify. Excel will then let you edit just that bar's properties. This two-step selection is the key difference from changing all error bars at once.

Start by clicking on your chart to enter edit mode. The chart border will show selection handles. Then click on any error bar in the series—you'll see all the error bars highlight with small square handles at each end. This means the entire series is selected. Now click once more on the specific error bar you want to change. That single bar will show its own set of handles, separate from the others.

Once that individual bar is selected, right-click it and choose Format Error Bars from the menu. The Format Error Bars pane will open on the right side of your screen, showing options for just that bar. You can now adjust its length, direction, or style independently.

Key Takeaways

  • Click the chart once to enter edit mode, then click an error bar to select the entire series, then click the specific bar again to select only that one.
  • Right-click the selected individual bar and choose Format Error Bars to open the editing pane for that bar alone.
  • You can change the error bar length by entering a custom value, percentage, or standard deviation amount in the Format Error Bars pane.
  • If you need to change multiple bars that aren't all the same, you must repeat this process for each bar separately.
  • Clicking elsewhere on the chart will deselect your individual bar, so make all your changes before clicking away.

Understanding the selection process

Excel's selection works in layers. When you click an error bar the first time, you're selecting the entire series—all the error bars attached to that data series. You'll see this because every error bar in the group shows handles. This is the same as if you had clicked on the data points themselves.

The second click narrows the selection down to one bar. This is called a sub-selection. Only that single bar will show handles after the second click. If you accidentally click somewhere else on the chart, you'll lose this sub-selection and go back to the full series being selected. You'll need to click the individual bar again.

This layered selection system is the reason many people struggle with individual error bar edits—they think one click should do it, but Excel needs two. The first click says "I want to work with error bars," and the second click says "I want to work with this one."

Changing error bar length for a single bar

Once you have an individual error bar selected and the Format Error Bars pane is open, look for the Error Bar Options section. You'll see a dropdown menu that currently shows how the error bars are calculated—usually "Fixed value," "Percentage," or "Standard Deviation."

If you want to set a custom length for just this bar, make sure "Fixed value" is selected in the dropdown. Then enter the number you want in the field next to it. This number represents how far the error bar extends above and below the data point. For example, entering 5 means the bar will extend 5 units up and 5 units down from the point.

If your data uses percentages or standard deviations, you can change those values too. The pane will show different fields depending on which calculation method you choose. After you enter your number, press Enter or click elsewhere in the pane to explore the change. You'll see the selected error bar update when ready on the chart.

Changing error bar direction and style

The Format Error Bars pane also controls which direction the error bar points. Look for the Direction section, which usually shows three options: "Both," "Minus," or "Plus." "Both" means the bar extends equally above and below the data point. "Minus" shows only the bar extending downward, and "Plus" shows only upward.

You can set a different direction for each individual error bar. For example, you might want one bar to show only the downside risk while another shows both directions. Select the bar, open the Format pane, and choose the direction you need.

Under the Line section, you can change the color, width, and dash style of just that error bar. Click the color box to pick a new color, or use the width slider to make the line thicker or thinner. These changes explore only to the bar you have selected, so you can make each bar visually distinct if needed.

Working with error bars on different data series

If your chart has multiple data series, each with its own error bars, the selection process is the same but you start by clicking the error bars of the series you want to edit. For example, if you have a chart showing sales data for three regions, each region has its own set of error bars. Click on the error bars for Region A first to select that series, then click the individual bar within that series you want to change.

This matters because you can't select an error bar from Region A and an error bar from Region B at the same time. Each series must be edited separately. If you need to make the same change to bars across different series, you'll repeat the process for each series.

Common mistakes to avoid

The most common mistake is clicking only once and thinking you've selected an individual bar. You'll then right-click and see options for the entire series, not just one bar. Remember: first click selects the series, second click selects the individual bar.

Another mistake is clicking on the data point instead of the error bar itself. The data point and error bar are separate objects in Excel. If you click the point, you'll select the data series, not the error bars. Make sure you're clicking directly on the error bar line, not the dot or marker at the center.

Don't forget that clicking anywhere else on the chart will deselect your individual bar. If you need to make multiple changes to one bar, do them all while the bar is still selected. Once you click away, you'll have to go through the two-click selection process again.

Frequently Asked Questions

Can I change the error bar for just one data point?

Yes. Each data point has its own error bar, and you can edit them individually. Select the error bar series, then click the specific bar attached to the data point you want to change. The bar will show its own handles, and you can then format it separately from the others.

What if I want to delete just one error bar?

Select the individual error bar using the two-click method, then press Delete. Only that bar will be removed. The other error bars in the series will remain. If you want to delete all error bars at once, select the entire series with one click and press Delete.

Can I copy the format from one error bar to another?

Excel doesn't have a built-in format painter for error bars, so you'll need to manually enter the same values in the Format Error Bars pane for each bar. Select the first bar, note its settings, then select the second bar and enter the same values. It takes a few extra clicks but ensures consistency.

Why does my error bar disappear after I select it?

This usually means you clicked on the data point instead of the error bar itself. Click away to deselect, then try again. Make sure you're clicking on the error bar line—the thin line extending from the data point—not the point itself. If the error bar is very short, click near the end of the line rather than at the center.

Can I make different error bars different colors?

Yes. Select each individual error bar and use the Format Error Bars pane to change its color under the Line section. You can make each bar a different color, though this is rarely useful for readability. Most charts look cleaner when all error bars in a series match.
