Line Graph

Dear all,
I have n=1000 and 14 columns in my data set: X1_a, X1_b, X2_a, X2_b,...,X7_a,X7_b. Each Xj (j=1,2,...7) was measured twice (which values are within the 0-10 range), thus, there are subcripts 'a' and 'b' to represnt before and after measures of Xj. I want to create a line graph such that the seven variables (X1, X2, ...X7) are placed in the horizontal line while the vertical line is the 0-10 range. Thus, the graph has two lines representing the before and after measures. Your help is highly appreciated. Thank you. ===================== To manage your subscription to SPSSX-L, send a message to [hidden email] (not to SPSSX-L), with no body text except the command.

What does the Y axis measure?

You could restructure the data (with VARSTOCASES) to get all of the Y-axis values into a single column, with index variables for X (1-7) and pre-post (1-2). After doing that, making the graph you desire should be fairly straightforward. I think Marta posted an example of this not too long ago.

Use VARSTOCASES to create a file where each record contains a single value (let’s call it Y)) corresponding to a satisfaction score and two index variables corresponding to the 7 X variables (let’s call it test) and the 2 times (let’s call it time). Then pick your favorite graphics menu choice: legacy dialogs, chart builder, … and assign Y to Y, test to X, and time to the grouping variable or legend variable. Specify Mean as the summary measure for Y. The biggest issue is to get the data into the shape that the graphics command expects and that is what VARSTOCASES will do for you.
