How to Add Points on Line Graph in Excel

Adding Data Points by Dragging

Adding Data Points Using Select Data Dialog

Click the chart to activate the Design tab. Click 'Select Data' in the Data group. Under 'Legend Entries (Series)', click Add. Enter a series name or select a cell containing the name. Click in 'Series Values' box, clear existing content, and select the range for your y-values. Click OK to complete.

Adding Markers to Data Points

Select the data series and click the data marker. Access Marker Options under Format Selection. Choose Built-in under Marker Type. Select your preferred marker style in the Type box and set the size. Customize marker appearance using Marker Fill options.

Alternative Methods

For precise point plotting, use an XY Scatter chart instead of a line chart. This allows you to position points accurately on the X axis. You can use formulas to look up current levels from your data and add them as a new series to the existing chart.
