Animated Bullet at the End of the Series
Displaying a pulsating element at a data point on a chart is a great way to attract viewer’s attention. This demo shows you how to do it with amCharts.
Key implementation details
To achieve this effect we create a bullet comprising of two circles. Then we animate both radius and opacity on one of them using built-in animation tools. And that’s it.
