我剛剛發現了Chart.js,它看起來很神奇!所以我試圖按照一個例子,它不起作用,說new Chart(ctx, options).Pie(data);
是無效的((intermerdiate value).Pie(...)
不是一個函數)。然後,我發現版本2中的語法已更改,因此我將其更改爲您在下面找到的內容。我不再有任何錯誤,但沒有任何內容顯示在我的畫布上。Piechart不顯示在畫布上

};
var ctx = $('#myChart').get(0).getContext('2d');
var myPieChart = new Chart(ctx, {

});
});
但是,當我使用它時,我得到以下錯誤:http://puu.sh/lAnIW/825e750586.png – OmniOwl
如果我複製並粘貼我在該例中看到的東西,我會得到:'(intermediate value).Pie is不是一個函數,就像我在開篇中所說的那樣。 – OmniOwl
好的,我自己解決了。我用他們的例子去了他們的網站,檢查了資料,看起來他們在內部仍然使用v1,所以我剛剛拿到了,現在我的圖表顯示出來了 – OmniOwl
