Greetings!
I created a 1-to-1 crossplot graph comparing X to Y values.
Not I want to develop expressions for reference lines in blue showing the narrowest corridor parallel to bisect including all data points:
To me, it seems that that the expression for the lower line is:
x-L, where L=abs(min(plotdata(1, Y)-plotdata(1, X)))
However, this doesn't seem to be working.
Can you suggest an effective workaround, please?
Thank you.

This is how the resulting text object looks like:

Well, in reference line setting, you can also use $() substitution to get the value.

Dear James,
Great news!
It is worth adding to help about on Reference Lines.

You can add a text object and use a piece of LT script, see below:
range -wx rx = 1;
range -wy ry = 1;
Text.text$ = $(abs(min(ry-rx)), .2);

How do I add a text object showing the result of the following calculation for a scatter plot to the graph?
abs(min(plotdata(1, Y)-plotdata(1, X)))
Thank you.

On the same Reference Lines setting dialog, find the Label node, and check the box Show. It will show the formula of the line.

Yes, it shows the general formula. However, it would be great to display the effective equation for the particular line.
Besides the default font settings option would also be useful.

Dear James,
Hm... I started working fine for me as well.
I will keep an eye on this.
How do I output the resulting expression (or at least L value) as a reference line label?
