Overlapping histograms in SPSS with multiple variables

Question

I have three index variables and I want to show how the variables differ in their distribution. Is it posible to make a single figure in SPSS, containing overlapping histograms for three different variables?

I want something like this:

Note, I do not want to create an overlapping histogram based on a single quantitative variable and a categorical variable, but on three different quantitative variables.

Answer 1

Since you know how to run a histogram on one quantitative variable + a categorical variable, you can simply restructure:

varstocases /make val from x y z/index=var(val).

Now you can use val as your single quantitative variable, and var (which contains the original variable name) as your categorical variable.

If you want to do the above without losing your present data structure, you can do this:

dataset name PresentStructure.
dataset copy ForAnalysis.
dataset activate ForAnalysis.
varstocases /make val from x y z/index=var(val).
.... Run your analyses here ......
dataset activate PresentStructure.
dataset close ForAnalysis.
