To create a pie chart, as in Example 8 of Section 2-4,
first enter the category names or labels in a column,
then enter the corresponding frequency counts an another column.
See the Data screen at the end.
Click on Graphcs, then select Pie Chart.
In the first box ("Categories in") enter the column containing the category names.
In the second box ("Counts in") enter the column containing the frequency counts.
By clicking on Next, you can get some options for how the results are displayed.
The pie chart below results from the data table at the bottom, and it is the default obtained by clicking on "Create Graph."
Pie charts are commonly used in the media, but among professional statisticians and among those who specialize in the graphic depiction of data, pie charts are not considered to be a very good tool.
