How to Add a Vertical Line to a Horizontal Bar Chart

Turning the Series into a Vertical Line

We’ll now see the bars from the Average series on the chart, but we want the Average value to be a vertical line. To do this, right-click on one of the bars and choose Change Series Chart Type.

Change Series Chart Type

In the Change Chart Type dialog that appears, choose the X Y (Scatter) option that shows straight lines with no marks.

Excel isn’t smart enough to display the line the way we want so we need to go back and edit the series again. Select the chart, and choose Select Data from the Chart Tools’ Design menu again.

Select Data

In the Select Data Source dialog, choose the Average series and click Edit.

Edit Series Button

We need to specify Series X and Series Y values for our vertical line. Series X Values should be the place on the x-axis where we want the vertical line. In the example, this is the Series X Value:


Series Y Values just need to be two values that are separated by a set interval. The numbers don’t matter so we can use 0 and 1. In the example, this is the Series Y Value:


Edit Average Series

Click OK and you will see the vertical line at the average value on the chart.

To make the line span the entire chart, we need to adjust its y-axis. Double-click the secondary axis on the right side of the chart.

Secondary Axis

In the Format Axis dialog under Axis Options, set the Minimum and Maximum as the numbers specified in the average value series (in the example, the Minimum is 0 (zero) and the Maximum is 1).

Once you’ve adjusted the secondary y-axis limits, you can delete it from the chart. Select the numbers on the right side and press Delete. You’ll be left with a clean vertical line on the horizontal bar chart.
