Scatter Plot Chart with Linear Trend Line in Reporting Modul

I have a report that I’m trying to make in the reporting module and I’m wondering, is there a way to add another type of plot on top of the chart?

For instance, I have a scatter chart of two different values displayed in the scatter chart. I also have average trend values that I would like to display as a line chart within the same chart. Is that possible?

So I would have a reporting chart with scatter chart shapes representing two values and the average trend for those values displayed as a line chart within the same chart.

If not, is there a way to overlay the line chart on top of the scatter chart and set the transparency of the chart background to see through the chart to the background scatter chart? I adjusted transparency yet it only adjusted the boarder elements of the chart.

Something similar to the attached snippet of an excel spreadsheet chart.

Thanks in advance for your help!

Found out how to accomplish what I was wanting from within the vision module instead of reporting. Found it via this previous post.
