Building a pump curve and then plotting other points (for pump performance) against it

[dbakeg00]

Hello.  I'm new to PowerBi.  My objective is to build a curve for pump performance (flow on the x-axis and pressure on the y-axis).  These curve performance numbers would be from the original performance test (when the pump was new).  Additionally, I would then like to plot the performance of the pump in the subsequent years...except the pump is not tested at all of the flows it was during the original test thus I would only need to plot 2-3 points in a given year rather than the entire curve.  Hopefully, my description is clear.  I've included a graphic as an example to show the final product looks like in my mind.  In this graphic, the line with the yellow dots is the original test and then the individual colored dots are subsequent years (color coded by year).  

Like I said, I'm new at this so maybe what I'm asking is obvious.  Thanks in advance.

Hi @dbakeg00 ,

Please take a look at Spline chart.

Hi Jay.  Thanks for the response.  I looked at a spline chart and—if I'm understanding it correctly—it seems that it plots a line that is the average of a group of scatter plots.  If that it true, I don't believe it will work for me as I need to plot a function (as a line) and then plot a few independant points as scatter plot.  If my assumptions are incorrect, please let me know.  Thanks again.
