我试图将数据绑定到甜甜圈剑道组件。到目前为止，我的工作低于
js文件:
function createChart() {
$("#chart").kendoChart({
dataSource: {
transport: {
read: {
url: "/ert.mvc/Summary?id=23",
dataType: "json",
type: "GET"
}
}
},
title: {
position: "bottom",
text: "Share of Internet Population Growth"
},
legend: {
visible: false
},
series: [{
data: [{
type: "donut",
field: "newlyRequested",
categoryField: "source",
explodeField: "explode" },
{
type: "donut",
field: "pending",
categoryField: "source",
explodeField: "explode"
}]
}],
seriesColors: ["#42a7ff", "#666666"],
tooltip: {
visible: true,
template: "#= category # (#= series.name #): #= value #%"
}
});
}
我的api响应如下:-
{
total: 120,
pending: 25,
incomplete: 10,
newlyRequested: 10
}
我遵循https://demos.telerik.com/kendo-ui/donut-charts/donut-labels的例子。但我得到kendo.all.js:7786未捕获的TypeError: e.s slice不是一个函数错误。我的预期结果是我想显示甜甜圈图与未决，不完整…
有什么想法吗
首先，您的API响应错误。它应该是一个像这样的对象数组:
[
{type: "total", value: 120},
{type: "pending", value: 25},
{type: "incomplete", value: 10},
{type: "newlyRequested", value: 10}
]
根据上面的API响应，您必须更改您的series配置。最后，您的甜甜圈图配置应该如下所示:
