To make a histogram, go to the Graphs pull down menu amd select Histogram. The following screen should appear.

Select the variable that you are interested in by double clicking on it. If you hit "O.K.", now it will create a histogram.

However, it is always good to create a title to do this, click on the arrow next to Annotation, select "Title". You will get the following screen.

Now, click on O.K twice and you have your histogram.
