Thank you for your response,
I have downloaded the trial. But there doesn't seem to be a LinearGauge.xml for Fusion charts in the XT v3.3.1 SR3 version.
Has this been updated to be used from another xml file - or did it get discontinued? Here is a link to what I'm trying to use charts for.

I got the LinearGauge.xml but used it with the updated files for XT v3.3.1 SR3 but it still doesnt work.
Any ideas would be much appreciated.
