How to plot an affine function on a scatter plot ?

[#1]

Hi everyone,

I had a look on the forum how to plot a simple affine function (y=mx+b) but didn't get a clear answer how to do it.

Most of the time, questions was about linear trend which is done with Linest_m and Linest_b functions.

Here is my question :

I have a scatter plot with 1 dimension called A and 2 Measures called M1 and M2.

I now the m and the b of my affine function and want to plot it on the same scatter plot.

I would like to plot as a reference line the affine function y = m x M1 + B

How can I do it ?

Thank you

Alban

As far as I know you can't plot arbitrary lines on a scatter plot.
