使用 Google 图表传递数据

Question

我正在尝试使用 Google 图表传递数据，但我在控制台中收到一个错误，显示为 "Uncaught Error: Every row given must be either null or an array."

我已经在 Whosebug 上找到了这个 post，但它似乎并不适用。 Dynamic data with Google Charts。我的代码如下。

 function drawChart() {

        // Create the data table.
        var data = new google.visualization.DataTable();
        data.addColumn('string', 'Topping');
        data.addColumn('number', 'Slices');
        data.addRows([
            {"somePercentage":"3.44","someId":"VZ"
            },
            {"somePercentage":"6.95","someId":"XOM"
            },
            {"somePercentage":"5.55","someId":"GG"
            },
            {"somePercentage":"10.53","someId":"INTC"
            },
            {"somePercentage":"8.39","someId":"TD"
            },
            {"somePercentage":"5.59","someId":"VOD"
            },
            {"somePercentage":"12.67","someId":"ARII"
            },
            {"somePercentage":"17.73","someId":"VVVVA"
            },
            {"somePercentage":"21.81","someId":"BSV"
            },
            {"somePercentage":"7.34","someId":"VNM"}
        ]);

我做错了什么？

Answer 1

好吧，看起来您正在添加对象作为您的行。

如果你这样做会怎样

data.addrows([
    ["3.44", "VZ"],
    ["6.95", "XOM"],
    ...
]);
