I attached a simple Excel file with two columns of data: dates and scores.
How can I create a column chart like this: http://peltiertech.com/images/2009-10/stackchartlabels02.png
where each column (A, B, C, etc...) is a quarter of year and the 3 colors are respectively:
- blue: the number of items with score < 3
- red: the number of items with score = 3
- green: the number of items with score > 3
