Whether you want to simplify your chart or emphasize certain data points, hiding or showing the chart axis in Excel can be an effective strategy. Here's how to do it:

Step 1: Select Your Chart

First, click on the chart where you want to hide or show the axis. This will activate the Chart Tools on the Ribbon.

Step 2: Open Chart Options

Go to the Format tab under Chart Tools on the Ribbon. In the dropdown list under the Current Selection group, select the axis (Horizontal Axis or Vertical Axis) that you want to hide or show.

Step 3: Hide or Show Axis

With the axis selected, go to the Format pane on the right side of the screen. Under the Axis Options category, check or uncheck the box for Axis Options > Labels > Label Position > None. Checking None will hide the axis, while unchecking it will show the axis.

Step 4: Validate Your Chart

Finally, ensure that your chart displays as intended. Repeat the steps for the other axis if needed.
