How do I add a numerical series of values to a chart over the X-axis but without the line?

I have a chart displaying two fitted curves.

I would like to add a third series that would consist of just the Y data values of the third series displayed just above the X-axis but with no line or line markers.

I can't just change the line color to "white" and display the Y values next to the hidden data points, as the text labels would end up outside the visible area of the chart.

I need the Y-values of the series to be printed just above the X-axis.

It needs to look like this where the two curves are my series 1 and 2, and the text turned 90 degrees would be the Y-values from series 3.

can you post example file of what you currently have.

you can add a series and plot the points wherever you need them and then link the data labels to cells which contain the data to be displayed.

see attached step by step instruction. Final touches left for you

You are welcome
