Trendline Display and Linear regression

Hello, I have a figure with 3 scatterplots and I wanted to add a trendline and the equation on each scatterplot. I've tries using the Tools>Basic Fitting fuction and it works but just for one graphs and when I try to do the same for the next graph, the trendline disappears from the initial graph. Also is there a way to add R^2 values? Here is a picture os my figure.

Thank you
