Yes, there is a way to add individual points to a line graph in Excel. Here are the steps:

1. Select the chart that you want to add the points to.
2. Click on the chart to activate the Chart Tools tab in the ribbon.
3. Click on the Design tab in the ribbon.
4. Click on the Select Data button in the Data group.
5. In the Select Data Source dialog box, click on the Add button in the Legend Entries (Series) section.
6. In the Edit Series dialog box, enter a name for the new series in the Series name field.
7. In the Series values field, enter the value for the point that you want to add.
8. Click on the OK button to close the Edit Series dialog box.
9. Repeat steps 5-8 for each point that you want to add.
10. Click on the OK button to close the Select Data Source dialog box.
