Hi there.
I'm doing control chart study and I have plotted one scatter plot in my
graph. I want to plot three more linear line inside the graph but I do not
know how to carry it out. The equation is something like y=0.2655, y=0.224,
y=0.304. Could anyone help me with this? I have allocated this task f\by my
supervisor as I'm a new trainee. Thanks.
