code: public void setAnimated(final boolean ANIMATED) {
          if (null == animated) {
              _animated = ANIMATED;
              updateChartData();
          } else {
              animated.set(ANIMATED);
          }
      }
docs: Defines if setting the value of the gauge should be animated using
  the duration defined in animationDuration [ms].
  Keep in mind that it only makes sense to animate the setting if
  the data rate is low (more than 1 value per second). If you use real
  live measured data you should set animated to false.
