I am afraid there is not a way to create the described scenario in the current version of RadControls
unless you overlay another resized RadGauge
so that the scales of both Gauges fit in.
I have tried some iterations to set such properties of both Gauges
and the CSS
classes of their wrappers so that I reproduce your scenario. You can have a look at the output here
Please find the VS sample I have used in RadHtmlGauge_overlaying.zip archive.
