我正在使用 Web Dataviz 包中的 Kendo UI 折线图来生成 500+ 的图表。但是图的负载太懒了。生成图表大约需要 25 秒。
我使用类别轴的日期和带有 odata 数据源的系列的十进制值。
我可以优化图表的加载时间吗?
$("#chart").kendoChart({
theme: $(document).data("kendoSkin") || "default",
dataSource: {
type: "odata",
transport: {
read: crudServiceBaseUrl + "/Odata/TestODataService.svc/EGauges"
},
serverFiltering: true,
serverSorting: true,
sort: { field: "DateData", dir: "asc"},
filter: [
{field: "From", operator: "eq", value: 422 },//400+
{ field: "Id", operator: "eq", value: parseInt(id) },
{ field: "Intervalo", operator: "eq", value: 23 },
{ field: "Tipo", operator: "eq", value: 'm' }
],
title: {
text: ""
},
legend: {
position: "bottom"
},
seriesDefaults: {
type: "area"
},
series: [{
field: "Value",
name: "Value"
}],
categoryAxis: {
field: "DateData",
labels: {
visible: false,
rotation: -90
}
},
axisDefaults: {
visible: true,
majorGridLines: { visible: false }
},
tooltip: {
visible: true
}
});
以下是 odata 服务返回数据的方式:
