如果你搜索我的问题，你会在fusioncharts网站上得到结果，但这不是我想要的。
我正在查询MySQL数据库中的数据，并将这些数据放入融合图表中以显示在我的网页上。我希望在同一页面上有2个图形，当您单击父图形上的一个数据点时，子图形将显示＆＃34;向下钻取＆＃34;图形。我怎样才能做到这一点？到目前为止，我可以按下父图，它将在新网页上打开子图。这是包含父图的主页的代码。该文件名为＆＃34; dept.php＆＃34;。

答案 0 :(得分：1)
n可以使用FusionCharts在单个页面中呈现多个图表。dataplotClick事件通过单击数据捕获正在生成的事件。setJSONData更新子图表，一个想要更新。这个的虚拟代码是：
FusionCharts.ready(function () {
var chart1 = new FusionCharts({
type: 'msstackedcolumn2d',
renderAt: 'chart-container1',
width: '550',
height: '350',
dataFormat: 'json',
dataSource: {
// enter the json data here
},
"events": {
"dataplotClick": function(eventObj, dataObj) {
/* so every time a dataClickEvent is being triggered from the data plot,
a new json `json2` is fetched from a sql query and
chart2 is updated with it.*/
chart2.setJSONData(json2);
}
}
}
}).render();
});
几天前我创建了这个fiddle，希望这在这里也很有用。这里我们有一个通用数据，而不是做一个SQL查询，每次点击，它在内部进行函数调用，并动态地创建一个数据。许多函数调用使它完全动态可能会使代码看起来很复杂。但是我在虚拟代码avobe中分享的基本哲学在这里是相同的。
用于快速参考的代码的片段版本。更好地在整页中运行结果以检查确切发生的事情。
