I have updated the sparklines generator to accept a new parameter 'limits' that sets the minimum and maximum values for the data you pass into the service. That will allow you to break free of the old restriction that all of the data must fall between 0 and 100. As usual feel free to use the online generator, the web service, or download and run the code on your own site.
