Check out http://chart.api.google.com and developers.google.com/chart for more detail
An example of a simple chart is
https://chart.googleapis.com/chart?cht=p3&chs=250x100&chd=t:22,22,22,4,30&chl=Server|WKS|Mac|Linux|Other
Just paste the above into your browser and see what happens
The trick is having this graph saved as a image file so it can then be included in your notes
The command used in the kaseya SD script would be somthing like
ExecuteCommandShell
cmd /c "[=userprofilefolder=]\..\webpages\install\curl.exe" "chart.googleapis.com/chart|WKS|Mac|Linux|Other" -o "[=userprofilefolder=]\[$TicketId$]-Random-image.png"
As this actually runs on the Kaseya Server you need to define using the userprofile where to store the image
Then to add the file just created to your ticket note use an Add Note step with
<img src="/images/chartimages/[$TicketId$]-Random-image.png" width="300" height="225" alt="" />
This is in theory how it works .. I'm just testing it and will try and post an actual working example ( with some hard coded values for the chart)
In a real situation you need to query the SQL database for the actual values you intend to graph
