I am trying to figure out how to create a pie chart using a group of numbers
without the pie chart interpreting the numbers as their values. For example,
if I select six tens(10) and two twenties(20), how do I get the pie chart to
give me two categories: 3/4 tens; 1/4 twenties. When I try to process these,
it gives me six different categories, proportions being equal to the value of
the number.
