add additional horizontal line on graph

Copper Contributor



I am wanting to add an additional horizontal line on this graph, it would be linear and at y=24.8. Seems a simple problem but cant figure out how to do it. I have attached my graph and table data.

Insert a new column between the Dimension column and the S275 column.

Select the empty cells immediately to the left of the data for the S275 series.

Enter 24.8 and confirm this value by pressing Ctrl+Enter.

That should add a horizontal line to the chart.
