Hi,

I have a follow-up question to a question answered helpfully by people on this list a few days ago.

My goal is simply to put a P value on a graph either in a text box or in the caption using *code*, not the Graph Editor.

I have a graph with one plot region with two separate graphs, based on the value of a certain grouping variable.

At the bottom of the graph, there is a note stating "Graphs by..." followed by the variable's label. I would like to replace this whole bit of text with the P value, but I cannot find out how. Each time I try to add a note or caption, the note or caption is repeated for each "instance" of the graph (see example code below). The text I want to replace is the "Graphs by..." bit. That is, instead of " P = 0.5" showing up below each graph in the code snippet below, I would like it to replace the very bottom text.

Does anyone know how to do this? Many thanks!

Phil Jones
