individual graphs of change
Locked

Hello, I have a file with multiple rows (4) for each subject, each row with a var value for a particular data point. I want to create a set of individual 'spaghetti' graphs mapping these 4 values for each subject. Any suggestions how I can do it in SPSS or where should I look for instructions? Thanks so much.

I googled spaghetti graph but the hits seemed to be about ecological modeling or path diagrams. Could you be a bit more specific or provide a URL to a similar example?

Let's say I have 20 participants, each with four rows of data for var1
and a variable Time with values 1-4 marking what time was each value collected at. I would like a graph with values of the var1 on y axis and values of Time on x axis and 20 lines on the graph showing the values of var1 at each time point for each of the participants. Any ideas how to do it in SPSS? Thanks!

I think this needs a 'wide' (horizontal) dataset (one row per client
with 4 vars instead of a 'long' (vertical) 4 rows per client dataset. Use CASETOVARS to convert then you should be able to do a chart of the 4 vars by time.

Ok, I finally figured out what I want to do. I apologize for the
half-a**ed previous posts. I want separate regression lines for each subject, all on one graph. I know how to run separate regression for each subject using BREAK BY ID command but I don't know how to get all the individual regression lines on one graph. I know how to request it in HLM but I would like to be able to do it in SPSS. Any ideas? Thanks.

Bozena,
Correct me if I'm wrong, but I think that you must be working on a multilevel analysis and you want to see either the individual points plotted by perons and then connected with lines or the individual regression lines through those points. Specific examples of both of these are described in Judith Singer's book. Unfortunately, mine is at home. Gene |

You have two sets of group dimensions here--per participant (20) and per value of the 4 vars. Crossing them would give you 80 lines on your chart. I guess that truly would be a mess of spaghetti. Is that what you want?

Thanks, Gene. I have the book and I found the syntax. It's done using
igraph. Now I have to go search through our list's archives to figure out the case limit for igraphs. I have 1200 cases (times 4 time points) and the igraph function I tried to run hung up on me instantly. I vaguely recall there was a discussion already on the case limits of igraph functions. Thanks again to all who helped me work through that. b. -----Original Message----- From: SPSSX(r) Discussion [mailto:[hidden email]] On Behalf Of Gene Maguin Sent: Thursday, April 12, 2007 1:48 PM To: [hidden email] Subject: Re: individual graphs of change Bozena, Correct me if I'm wrong, but I think that you must be working on a multilevel analysis and you want to see either the individual points plotted by perons and then connected with lines or the individual regression lines through those points.

You can do individual trajectories using the Chart Builder in SPSS 15. NOTE
that I have not pushed this "to the limit" with large datasets, but here's a small example. Consider two patients with a number of seizures noted over consecutive 2-week periods. Here are the data. Id Time Seizures 101 1 11 101 2 14 101 3 9 101 4 8 102 1 8 102 2 7 102 3 9 102 4 4 Make sure that ID has its MEASURE set to NOMINAL, while the others are set to SCALE. Then, you do a scatterplot of Seizures by Time, with ID as a GroupColor variable. After you generate the Chart, edit it and add interpolation lines. * Chart Builder. GGRAPH /GRAPHDATASET NAME="graphdataset" VARIABLES=time seizure id MISSING= LISTWISE REPORTMISSING=NO /GRAPHSPEC SOURCE=INLINE. BEGIN GPL SOURCE: s=userSource(id("graphdataset")) DATA: time=col(source(s), name("time")) DATA: seizure=col(source(s), name("seizure")) DATA: id=col(source(s), name("id"), unit.category()) GUIDE: axis(dim(1), label("time")) GUIDE: axis(dim(2), label("seizure")) GUIDE: legend(aesthetic(aesthetic.color.exterior), label("id")) SCALE: cat(aesthetic(aesthetic.color.exterior)) ELEMENT: point(position(time*seizure), color.exterior(id)) END GPL. -----Original Message----- From: SPSSX(r) Discussion [mailto:[hidden email]] On Behalf Of Zdaniuk, Bozena Sent: Thursday, April 12, 2007 2:00 PM To: [hidden email] Subject: Re: individual graphs of change Thanks, Gene.
