Hello Kathy
You can graph multiple variables using interactive graphs. It's a bit
difficult to describe, but you should be able to experiment.
Select Graphs, Interactive, Line.
The critical part is selecting the variables you need from the Right-hand
variable list - you need to select all three simultaneaoulsy (use ctrl-click
to pick them). Then move them all together into the x-axis box (the one
with the right arrow.) SPSS will automatically create two new variables for
you, one called category_set and one called value_set. Move the category_set
variable into the colour box to have different colored lines for each
variable (or into the style box to have different styles). Move the
value_set variable into the y-axis box, and time into the x-axis box. You
should get a plot of the three variables against time. You could also put
the School variable into the Panel box which would give you one graph with 3
lines for each of the schools.
If that's not exactly what you need, I'm sure a bit of playing around will
work for you once you have 'got it'.

Subject: Assistance with graphing multiple variables over repeated measures
Hi all,
I have data for 3 different variables, all on the same scale (1 to 4) for 4
schools, measured at 3 or 4 different time points (Nov, Jan, Apr and June
for one variable, and no Nov observations for the other 2). I would like to
present the data for those 3 variables with their repeated measures for the
4 schools within the same graph, if possible. I was envisioning a line
graph, with each line representing one of the 3 variables over time for each
of the schools. I cannot for the life of me figure out how to do that either
in Excel or SPSS. At best, I can put 2 graphs side-by-side. If it helps, the
data would look like this:
School A: Line 1: Global Ratings for Nov, Jan, April & June; Line 2: ILT
Environ for Jan, April & June; Line 3: Wrkgrp environ for Jan, Apr & June
Schools B - D would be the same.
Is there any way to do this in SPSS? I've just been using the graphing
function alone, not inside any analytic procedures like Repeated Meas ANOVA,
although that might work. If you have any suggestions, I'd appreciate it.
Thanks so much for your help!
Kathy McKnight
