我发现自己在这个网络开发项目中发现自己,并希望有人能帮助我更好地理解为什么我的某个谷歌图表不会在我的页面上绘制。
我有一个工作测试页面,图表绘制了我想要的方式,这是jsfiddle,所以如果你想测试你可以得到确切的代码 http://jsfiddle.net/dlaliberte/pfTqP/
我直接从这个有效的页面中提取代码,并将其放入我的页面中,该页面上已有4个其他正在运行的谷歌图表。现在,当我添加此图表时,它不会给我任何错误,但它不会绘制。
我将发布第一张图表的javascript以及我尝试修复的图表(以' ###'分隔)强大的>,以及我的页面上它应该绘制的位置,我希望有更多经验的人可以帮助我找出问题的来源,因为经过几个小时的调整和运行它我还不确定出了什么问题。

这就是我在我的页面上绘制图表的位置,它位于一组4个标签中,因此用户可以在不同的图表中进行选项卡,到目前为止,它的工作方式非常完美。

<ul class="nav nav-tabs" role="tablist" data-tabs="tabs">

我不确定您还需要看到什么,再次我在这里的元素,并试图掌握如何实现这一点,谢谢!
答案 0 :(得分:1)
这里有几个问题......
首先,代码与旧版和新版谷歌图表混合在一起
旧库使用jsapi
加载库
<script src="http://www.google.com/jsapi"></script>
新库使用gstatic
库
<script src="https://www.gstatic.com/charts/loader.js"></script>
根据release notes ...
通过
jsapi
加载程序保留的Google图表版本不再一致更新。请从现在开始使用新的gstatic
加载程序。
接下来,load
语句和callback
每页只能使用一次
一旦callback
触发,您可以根据需要绘制尽可能多的图表
callback
也可以直接放在load
声明
尝试设置类似以下内容......
google.charts.load('current', {
callback: drawCharts,
packages: ['controls', 'corechart']
});
function drawCharts() {
drawLineChart();
drawVisualization();
}
function drawLineChart() {
...
}
function drawVisualization() {
...
}
