Excel column charts have gaps between their bars by default.
Not everyone likes this default appearance, but fortunately it is possible to change the size of the gaps between bars and even remove them altogether.
1. Open the Format Data Series task pane
Right-click on one of the bars in your chart and click Format Data Series from the shortcut menu.
The Format Data Series task pane appears on the right-hand side of the screen, offering many different options.
Our Essential Skills course goes into great depth about formatting charts, but for the moment the Gap Width setting is the one you are interested in.
If this isn’t working quite the same way for you, it’s probably because you are using a legacy version of Excel. You should be able to figure out any differences found if you are not using the current version.
2. Set the Gap Width property
You should see a Gap Width setting on the Format Data Series task pane. You can use this slider to change the gap widths to your liking.
Your chart should change immediately!
