Wijmo的CompositeChart控件允许您使用一个Chart来分析和展现复杂的数据。相同的数据可以使用不同的可视化效果,不同的图表类型展现在一个图表内,使得用户可以从不同的角度,了解分析这组数据所表达的内容 。
本文将介绍如何使用Wijmo的CompositeChart控件,制作一个复合图表。CompositeChart 的API:http://wijmo.com/wiki/index.php/Compositechart,Wijmo 的CompositeChart 化繁为简,将传统 Excel like图表中的三大区域: Plot Area, Legend Area, Label Area, 分离成为更为简单的API: SeriesList, Legend, Axis, Hint, 使得开发者更加容易的理解和使用。

Wijmo的CompositeChart 依赖于下面的这5个核心的JavaScript库:
raphael.js
globalize.min.js
jquery.ui.widget.js
jquery.wijmo.raphael.js
jquery.wijmo.wijchartcore.js

如果需要加入别的类型的Chart,需要再引入其它Chart类型的JavaScript库,这样可以使得开发者可以灵活定制并裁剪出适合自己用例的 JavaScript库。例如本实例使用了 PieChart, BarChart, LineChart, 引入的JavaScript库如下:

jquery-1.7.1.min.js
jquery-ui-1.8.18.custom.min.js
globalize.min.js
raphael-min.js
jquery.wijmo.raphael.js
jquery.wijmo.wijchartcore.js
jquery.wijmo.wijbarchart.js
jquery.wijmo.wijpiechart.js
jquery.wijmo.wijlinechart.js
jquery.wijmo.wijcompositechart.js

写点代码,设置一下Chart :

 
$(document).ready(function () {
$("#wijcompositechart").wijcompositechart({
axis: {
y: {
text: "Total Hardware"
},
x: {
text: ""
}
},
stacked: false,
hint: {
content: function () {
return this.label + '\n ' + this.y + '';
}
},
header: {
text: "Hardware Distribution"
},
seriesList: [{
type: "column",
label: "West",
legendEntry: true,
data: { x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'], y: [5, 3, 4, 7, 2] }
}, {
type: "column",
label: "Central",
legendEntry: true,
data: { x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'], y: [2, 2, 3, 2, 1] }
}, {
type: "column",
label: "East",
legendEntry: true,
data: { x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'], y: [3, 4, 4, 2, 5] }
}, {
type: "pie",
label: "asdfdsfdsf",
legendEntry: true,
center: { x: 150, y: 150 },
radius: 60,
data: [{
label: "MacBook Pro",
legendEntry: true,
data: 46.78,
offset: 15
}, {
label: "iMac",
legendEntry: true,
data: 23.18,
offset: 0
}, {
label: "MacBook",
legendEntry: true,
data: 20.25,
offset: 0
}]
}, {
type: "line",
label: "Steam1",
legendEntry: true,
data: {
x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'],
y: [3, 6, 2, 9, 5]
},
markers: {
visible: true,
type: "circle"
}
}, {
type: "line",
label: "Steam2",
legendEntry: true,
data: {
x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'],
y: [1, 3, 4, 7, 2]
},
markers: {
visible: true,
type: "tri"
}
}
]
});
});

代码不多,很好分析:

 
--
axis: {
y: {
text: "Total Hardware"
},
x: {
text: ""
}
--
设置X,Y 轴。
---
stacked: false
---
设置Bar 为非stacked.
---
hint: {
content: function () {
return this.label + '\n ' + this.y + '';
}
},
---
设置鼠标 Tooltip.
---
header: {
text: "Hardware Distribution"
},
---
设置图表头.
----
seriesList: [{
type: "column",
label: "West",
legendEntry: true,
data: { x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'], y: [5, 3, 4, 7, 2] }
}, {
type: "column",
label: "Central",
legendEntry: true,
data: { x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'], y: [2, 2, 3, 2, 1] }
}, {
type: "column",
label: "East",
legendEntry: true,
data: { x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'], y: [3, 4, 4, 2, 5] }
}, {
type: "pie",
label: "asdfdsfdsf",
legendEntry: true,
center: { x: 150, y: 150 },
radius: 60,
data: [{
label: "MacBook Pro",
legendEntry: true,
data: 46.78,
offset: 15
}, {
label: "iMac",
legendEntry: true,
data: 23.18,
offset: 0
}, {
label: "MacBook",
legendEntry: true,
data: 20.25,
offset: 0
}]
}, {
type: "line",
label: "Steam1",
legendEntry: true,
data: {
x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'],
y: [3, 6, 2, 9, 5]
},
markers: {
visible: true,
type: "circle"
}
}, {
type: "line",
label: "Steam2",
legendEntry: true,
data: {
x: ['Desktops', 'Notebooks', 'AIO', 'Tablets', 'Phones'],
y: [1, 3, 4, 7, 2]
},
markers: {
visible: true,
type: "tri"
}
}
]

设置 SeriesList,每个Series 可以设置其type, label, legendEntry, data, 等等属性。 Series可以设置 SeriesStyles, 和 SeriesHoverStyles, 如:

 
seriesStyles: [{
fill: "#8ede43", stroke: "#7fc73c", opacity: 0.8
}],
seriesHoverStyles: [{
"stroke-width": "1.5", opacity: 1
}]
复制代码

经过上面的设置,这个CompositeChart就设置好了。也可以使用Server返回的 Json 数据动态绑定生成Chart。
