Question

我正在测试使用Kendo UI Pro套件创建SPA。我目前在使用Kendo UI Chart（在甜甜圈模式下）时遇到问题。图表的SVG在IE 10中没有正确呈现。这个问题似乎不会发生在IE 11或Firefox中。

JSFiddle示例：http://jsfiddle.net/m9vq7gu4/

在View的Show事件中，我调用ajax API并获取数据：

$.ajax({
    url: '/echo/json/',
    data: {
        json: JSON.stringify({
            "TotalHours": Math.random() * 714,
                "Budget": 714.6
        }),
        delay: 2
    },
    type: 'POST',
    success: function (response) {
        console.log(response);
        var data = [{
            value: response.TotalHours,
            color: "red"
        }, {
            value: response.Budget - response.TotalHours,
            color: "transparent"
        }];
        loadRadial(id, data);
    }
});

然后我将kendoChart div并刷新它。

var dsRadial = new kendo.data.DataSource({
    data: data
});
dsRadial.read();
var radial = $("#" + id).kendoChart({
    dataSource: dsRadial,
    dataBound: function () {
        console.log("dataBound");
    },
    legend: {
        visible: false
    },
    seriesDefaults: {
        type: "donut",
        holeSize: 60,
        size: 20
    },
    series: [{
        field: "value",
        colorField: "color"
    }],
    chartArea: {
        background: "transparent"
    },
    tooltip: {
        visible: true
    }
}).data("kendoChart");

我显示View / Layout / Router下的所有事件都正确触发。起初我认为图表没有正确绑定，但如果我查看页面的源代码，就会创建SVG：

真正奇怪的是，只要我将路由器切换到另一页，SVG就会正常显示，直到再次更改数据（您可以通过点击演示中的主页/数据链接看到这一点）。除了图表和视图/布局/路由器之间的奇怪问题之外，还有什么可能导致这种情况？

这是版本2013.2.1215（内部版本）之前的Kendo UI的已知问题。

这是由IE10 SVG实现中的故障引起的。一旦路径缩放为0，即使转换被清除，它也会消失。

Kendo Chart控件在IE 10中无法呈现正确的SVG
