Histogram From Weighted DataJan 12, 2010
I'm trying to use the 2007 histogram tool (or frequency) to show me the frequency of data, but my data is in a different form than required for either of these tools. Let me use the following simple case -- to show the frequency of student grades both tools assume I have a list of student's test grades. What if I instead have more than one column, e.g., "grade" and "number students with that grade"??
My application is actually different, but it's still 2 columns, a numeric property and a weighting factor (e.g., fraction of the total).
