Cognos Widgets

[rrdeng]

I'm trying to incorporate a thermometer or barometer type of widget into my dashboard report in order to gauge progress (think 100% stack chart but instead of bars, there will be thermometer graphics).  I cannot seem to find anything in the standard Cognos install that fits these needs.

Does anyone know where additional Cognos widgets can be found and downloaded?  Or is it possible to create my own graphic/widget or edit an existing one?

Thanks!
