Session Model Chart Problem

[Agentshevy]

I am trying to chart data using the session model file from Tom Geist, the chart on the file is supposed to display Sales from the current month, with respect to the status of the sales. (Closed and Open). However, the chart is not actually displaying correctly. I am trying to implement the session model on my database, but this issue of the chart not displaying the accurate data is posing a problem. From the records in the file, the sales have more Open sales than Closed ones, also the current sales for the month of february has no closed sales. . 

Please can someone assist me .. thanks
