Unable to set an initial value for any of the gauges

Issue #36 resolved
Patrick Kutch
created an issue

Attached is a modified version of DemoGauge that shows the issue.

I've tried the .value in the builder and the setValue() function, neither works.

I want to be able to set an initial value during init, but this does not work.
