If the gauge must display a huge range of values (e.g. Min=0, Max=500 000) having visible MinorTicks blocks the browser and ultimately throws an "out of stack space error".

The workaround is to set 
MinorTicks.Visible = false 
or Scale.MinorUnit to a sufficiently large value. If the minor unit is not set properly the minor ticks will clutter together and will be unreadable.
