Angular Guages in with SpotOn Vantage vCharts!
Posted by Mark Mallany on Fri, Apr 23, 2010
Hi everybody,
I hate to state the obvious, but angular gauges are a really cool. They are also a gauge that can easily and quickly be made to look very different. Specifically, altering the starting and end angles slightly you can quickly and easily change how your data is interpreted.
Here are a few examples using the same data and color ranges as the previous post (in brackets I have included their start (S) and end (E) angles) :
the default {S:180,E:0}:
the backwards {S:0,E:180}: 
The almost full circle {S:150:E:-150}
Here are a couple handy reminders about the (S)tart and (E)nd angles:
- When S > E the gauge will be clockwise.
- When S < E the gauge will be counter-clockwise.
- You probably want to keep the difference between start and end under 360 (or vice versa).
