This is pretty handy because in a few lines of FXG you are able to draw something that would have required much less flexible code to be written in Flex 3.

I couldn’t resist to give it a try, and defining the graphical representation of an ILOG Elixir Gauge using Gumbo FXG.

However in some cases you might want to display the current value using a different pattern than pointing the value. A typical example is a light ramp gauge that is displaying the current value using color lighting on a ramp such as in the following example:

In this post, I will use ILOG Elixir Gauges framework to build a circular gauge which blinks if the value of the gauge is greater than a threshold value. This kind of gauge can be useful to point out critical…
