我刚刚发现了Chart.js,它看起来很神奇!所以我试图按照一个例子,它不起作用,说new Chart(ctx, options).Pie(data);
是无效的((intermerdiate value).Pie(...)
不是一个函数)。然后,我发现版本2中的语法已更改,因此我将其更改为您在下面找到的内容。我不再有任何错误,但没有任何内容显示在我的画布上。Piechart不显示在画布上

};
var ctx = $('#myChart').get(0).getContext('2d');
var myPieChart = new Chart(ctx, {
type: "pie",
data: data,
options: options
});
});
但是,当我使用它时,我得到以下错误:http://puu.sh/lAnIW/825e750586.png – OmniOwl
如果我复制并粘贴我在该例中看到的东西,我会得到:'(intermediate value).Pie is不是一个函数,就像我在开篇中所说的那样。 – OmniOwl
好的,我自己解决了。我用他们的例子去了他们的网站,检查了资料,看起来他们在内部仍然使用v1,所以我刚刚拿到了,现在我的图表显示出来了 – OmniOwl
