In the attached chart, I had some data on the worksheet that I need to add as a horizontal title on top of the chart and I'd like to know if there is some way to add the data to the chart directly from the sheet, or if I have to do it manually. In column D, Hours after Workout, I would like that to be the horizontal axis title above the chart and the corresponding numbers reflected as labels. I've attached a PDF that shows how it looks penciled in. The hours/days do not have to line up perfectly with the dots on the line chart, I just need the labels on top of the chart. Is there some way to do this by incorporating the data directly from the sheet, or do I need to create labels manually, and if so, how?
