Animated gauge

This demo shows how to implement dynamic, good-looking dashboards. The gradient fill of the GaugeBand is achieved via <a href="http://docs.amcharts.com/3/javascriptcharts/GaugeBand#gradientRatio"><code>gradientRatio</code></a> setting. The arrow and band angle is updated via <a href="http://docs.amcharts.com/3/javascriptcharts/GaugeArrow#setValue"><code>setValue()</code></a> and <a href="http://docs.amcharts.com/3/javascriptcharts/GaugeBand#setStartValue"><code>setStartValue()</code></a> / <a href="http://docs.amcharts.com/3/javascriptcharts/GaugeBand#setEndValue"><code>setEndValue()</code></a> API functions respectively.
