How can i add 1 line of median into the scatter chart below?izzit possible??
I hope to get the result shown as below. The median line can across all the point but the remainded point should be there also....
Properties -> Presentation tab -> Reference Lines -> Add -> Type expression and choose the axis.
This is what i did.....but still unable to add the median line...izzit my wrong??
The reference line is always horizontal.
Use trendlines feature on expression tab if you want to show linear regression.
