Add A 45 Degree Line In Excel Chart

Excel charts are a great way to present data visually. However, sometimes it can be difficult to see trends or compare data points on a chart. Adding a 45 degree line to your chart can help with this issue. This line represents a 1:1 ratio and makes it easier to compare data points. In this article, we'll show you how to add a 45 degree line to your Excel chart.

Step 1: Create Your Chart

The first step in adding a 45 degree line to your Excel chart is to create the chart. This can be done by selecting the data you want to use and then clicking on the "Insert" tab. From there, you can choose the type of chart you want to create.

Step 2: Add a New Series

Next, you'll need to add a new series to your chart. This can be done by right-clicking on the chart and selecting "Select Data". From there, click on "Add" to create a new series. Name the series "45 Degree Line" and choose a blank cell for the "Series X values".

Step 3: Enter 45 Degree Values

Now you'll need to enter the values for the 45 degree line. In the "Series Y values" field, enter the same value you used for the maximum value on your chart. For example, if your chart goes up to 100, enter 100 for the Y value.

Step 4: Change the Chart Type

The next step is to change the chart type for the 45 degree line series. Right-click on the series and select "Change Series Chart Type". Choose "Scatter with Straight Lines and Markers" and click "OK".
