This sample demonstrates how to specify nested radial gauge scales.
The largest scale shows the hours and minutes, while the upper right scale shows 24 hours based hour. The bottom scale shows the current seconds. Upper left scale could be used to display a chronograph minutes, and the largest red needle to display the chronograph seconds. For detailed implementation, please take a look at the HTML code tab.
