AmBalloon

Type class

AmBalloon is the class which generates balloons (datatips). Balloon follows the mouse when you roll-over the pie slice/line bullet/column/etc, chart indicator of serial charts displays value balloons and category balloon. Balloon instance is created by the chart automatically and can be accessed via "balloon" property of AmChart. Chart shows/hides and sets position for every balloon automatically, so all you need to do is to change balloon appearance, if you want to. For example:

chart = new AmCharts.AmSerialChart();
// get balloon intance
var balloon = chart.balloon;
// set properties
balloon.adjustBorderColor = true;
balloon.color = "#000000";
balloon.cornerRadius = 5;
balloon.fillColor = "#FFFFFF";```
