當鼠標懸停時，amcharts氣球可見性？

Question

如何在鼠標懸停時使amcharts氣球可見？這裏是關於氣球的文檔http://docs.amcharts.com/2/javascriptcharts/AmBalloon

Answer 1

例如，如果您使用列類型。氣球出現在默認情況下。

var graph = new AmCharts.AmGraph(); 
graph.valueField = "visits"; //this is from my Json data 
graph.type = "column"; //here is the type of graph 

現在，如果你願意，你可以訪問和修改氣球對象

// here I modify the default outputted text  
graph.balloonText = "[[category]]: <b>[[value]]</b>";
