我的json:
var stats = [
{ value: 30, date: new Date("2015/04/12"), No: 1 },
{ value: 50, date: new Date("2015/04/12"), No: 2 },
{ value: 45, date: new Date("2015/04/12"), No: 3 },
{ value: 30, date: new Date("2015/04/13"), No: 1 },
{ value: 50, date: new Date("2015/04/13"), No: 2 },
{ value: 45, date: new Date("2015/04/13"), No: 3 },
{ value: 30, date: new Date("2015/04/14"), No: 1 },
{ value: 50, date: new Date("2015/04/14"), No: 2 },
{ value: 45, date: new Date("2015/04/14"), No: 3 }
];
我的代码:
function createChart() {
$("#chart").kendoChart({
title: {
text: "72小时能耗状况图"
},
dataSource: {
data: stats
},
seriesColors: ["#3A5FCD"],
series: [{
type: "column",
field: "value",
categoryField: "date"
}],
categoryAxis: {
baseUnit: "days",
majorGridLines: {
visible: false
}
},
valueAxis: {
line: {
visible: false
}
}
});
}
我想每天有三个酒吧,1,2,3。 不同的日子有不同的颜色。
如何修改代码?
你能理解我吗?答案 0 :(得分:0)
设置一个dataSource对象,并在" No"上进行分组。字段:
var statsDataSource = new kendo.data.DataSource({
data: stats,
group: {
field: "No"
},
sort: {
field: "date",
dir: "asc"
},
schema: {
model: {
fields: {
date: {
type: "date"
}
}
}
}
});
然后在创建图表时使用该dataSource:
$("#chart").kendoChart({
title: { text: "72小时能耗状况图" },
theme: "Metro",
dataSource: statsDataSource,
series: [{
type: "column",
field: "value",
categoryField: "date",
name: "#= group.value #"
}],
legend: {
position: "bottom"
},
valueAxis: {
line: {
visible: false
}
},
categoryAxis: {
baseUnit: "days",
majorGridLines: {
visible: false
}
}
});
