Redirect the output from Javascript to display Graph

Hi,

I have written a function in afterFactory event to fetch the data and do some calculations based on the creation date. After I finish all my calculations, I set the values to globalvariable...

reportContext.setPersistentGlobalVariable("Jan_Count", jan_count) ;
reportContext.setPersistentGlobalVariable("Feb_Count", feb_Count) ;
reportContext.setPersistentGlobalVariable("Mar_Count", mar_Count) ;
reportContext.setPersistentGlobalVariable("Apr_Count", apr_Count) ;
reportContext.setPersistentGlobalVariable("May_Count", may_count) ;
...
...
...

Now... I want to display the bar graph using the data...
Is there any method where i can get the persistent global variable data and create a chart...

Please give me some suggestion or point me to some documentation where I can take forward...

Thanks In advance...

What calculations are you preforming on the data? Can you create a computed column and use that to make your chart?
