使用echarts开发电子屏数据展示页面
背景
之前的项目因为要顾及体量问题，选用了highchart，没用上echarts；这次因为是本地部署电子屏幕的展示页，不需要考虑体量大小，直接用上了echarts；用起来觉得非常不错，特别是地图上非常炫酷的飞机飞行动画，吊炸天了。美中不足的地方是x轴上文字展示部分，想加些个性化的icon不支持，柱状图每条柱想用不同的颜色也不支持，那只能让设计师妥协了，呵呵！

一、地图的实现
注意要先引入地图依赖数据china.js或者异步请求china.json文件，其他代码如下：
//地图

var convertData = function (data) {
var res = [];
for (var i = 0; i < data.length; i++) {
var dataItem = data[i];
var fromCoord = geoCoordMap[dataItem[0].name];
var toCoord = geoCoordMap[dataItem[1].name];
if (fromCoord && toCoord) {
res.push({

setInterval(function () {
dMapChart.dispose();
$("#d_map").html("");
dMapChart = echarts.init(document.getElementById('d_map'));
dMapChart.setOption(option);

});
二、会员总数变化实现
这里用了比较流行的css3动画库animate.css中的flipInX翻页效果来展示数据变化，代码如下：
//模拟读取并修改显示
var _oldVal = $("#member_count").attr("data-value");
setInterval(function () {
var newVal = $("#member_count").attr("data-value"),
oStr = _oldVal.toString(),
nStr = newVal.toString();
if (_oldVal != newVal) {
_oldVal = newVal;
var oCharArr = oStr.split(""),
nCharArr = nStr.split("");
if (oStr.length == nStr.length) {
for (var i in oCharArr) {
if (oCharArr[i] != nCharArr[i]) {
var $img = $("#member_count").find(".no img:eq(" + i + ")"),
src = $img.attr("src");
$img.attr("src", src.replace(oCharArr[i] + ".png", nCharArr[i] + ".png")).addClass("animated flipInX").one('webkitAnimationEnd mozAnimationEnd animationend', function () {
$(this).attr("class", "");
});
}
}
} else {
var imgGapNo = nStr.length - oStr.length;
var _img = $("#member_count").find(".no img:eq(0)"),
_no = $("#member_count").find(".no");
for (var i = 0; i < imgGapNo; i++) {
_no.append(_img.get(0).outerHTML);
}
for (var j in nCharArr) {
var $img = $("#member_count").find(".no img:eq(" + j + ")"),
src = $img.attr("src");
$img.attr("src", src.replace(/\d{1}.png/, nCharArr[j] + ".png")).addClass("animated flipInX").one('webkitAnimationEnd mozAnimationEnd animationend', function () {
$(this).attr("class", "");
});
}
}
}
}, 5000);
三、会员年龄分布
代码如下：
// 图一、按年龄显示销售数据及客户数
var salesData = [10000, 10500, 10700, 25000, 11200, 9175, 8850],
customersQtyData = [100, 105, 107, 150, 200, 175, 50];
function genAgeOption(salesData, customersQtyData) {
return {
color: ['#dedd74', '#4fc0f5'],
tooltip: {

},
toolbox: {
feature: {
dataView: { show: false, readOnly: false },
magicType: { show: false, type: ['line', 'bar'] },

}
]
}
}
var ageOption = genAgeOption(salesData, customersQtyData);
var ageChart = echarts.init(document.getElementById('chart_by_age'));
ageChart.setOption(ageOption);
// 基于准备好的dom，初始化echarts实例
setInterval(function () {
ageChart.dispose();
$("#chart_by_age").html("");
ageChart = echarts.init(document.getElementById('chart_by_age'));
ageChart.setOption(ageOption);
}, 22000);
四、会员性别分布
代码如下：
// 图二、按性别显示销售数据及客户数
var salesDataByGender = [1000000, 2500000],
customersQtyDataByGender = [100000, 250000];
function genGenderOption(salesData, customersQtyData) {
return {
color: ['#dedd74', '#4fc0f5'],
tooltip: {
trigger: 'axis'
},
toolbox: {
feature: {
dataView: { show: false, readOnly: false },
magicType: { show: false, type: ['line', 'bar'] },
restore: { show: false },
saveAsImage: { show: false }
}
},
grid: {
x: 100,
x2: 100
},
legend: {
data: ['累计销售额(元)'],
top: 'bottom',

}
},
xAxis: [
{

},
type: 'category',
data: ['男', '女'],
axisLine: {

}
}
],
yAxis: [

min: 0,
axisLine: {

splitLine: { show: false }
},
{
type: 'value',

min: 0,
axisLine: {
lineStyle: {

}
},
splitLine: { show: false }
}
],
series: [
{
name: '累计销售额(元)',
type: 'line',
smooth: true,
data: salesData
},
{
name: '客户数',
type: 'bar',
yAxisIndex: 1,
data: customersQtyData
}
]
};
}
var genderOption = genGenderOption(salesDataByGender, customersQtyDataByGender);
var genderChart = echarts.init(document.getElementById('chart_by_gender'));
genderChart.setOption(genderOption);
// 基于准备好的dom，初始化echarts实例
setInterval(function () {
genderChart.dispose();
$("#chart_by_gender").html("");
genderChart = echarts.init(document.getElementById('chart_by_gender'));
genderChart.setOption(genderOption);
}, 17000);
五、月每端销售数据
代码如下：
// 图一、按客户端类型显示销售笔数及销售额
var orderCount = [121, 312, 55],
salesData = [26541, 60004, 10242];
function getChannelBarOption(orderCount, salesData) {
return {
color: ['#dedd74', '#4fc0f5'],
tooltip: {
trigger: 'axis'
},
toolbox: {
feature: {
dataView: { show: false, readOnly: false },
magicType: { show: false, type: ['line', 'bar'] },
restore: { show: false },
saveAsImage: { show: false }
}
},
grid: {
x: 60,

},
legend: {
data: ['销售额','销售笔数'],
top: 'bottom',
left: 'center',
textStyle: {
color: '#fff'
}
},
xAxis: [
{
axisLabel: {

},
type: 'category',
data: ['微信端', 'APP端', 'PC端'],
axisLine: {
lineStyle: {
color: '#95a7c5'//设置x轴颜色
}
}
}
],
yAxis: [
{
type: 'value',
name: '销售笔数',
min: 0,
axisLine: {
lineStyle: {
color: '#95a7c5'//设置图形左侧颜色
}
},
splitLine: { show: false }
},
{
type: 'value',
name: '销售额',
min: 0,
axisLine: {
lineStyle: {
color: '#95a7c5'//设置图形右侧颜色
}
},
splitLine: { show: false }
}
],
series: [
{

type: 'line',
smooth: true,
data: orderCount
},
{
name: '销售额',
type: 'bar',
yAxisIndex: 1,

}
]
};
}
var channelBarOption = getChannelBarOption(orderCount, salesData);
var chanelBarChart = echarts.init(document.getElementById('channel_bar'));
chanelBarChart.setOption(channelBarOption);
// 基于准备好的dom，初始化echarts实例
setInterval(function () {
chanelBarChart.dispose();
$("#channel_bar").html("");
chanelBarChart = echarts.init(document.getElementById('channel_bar'));
chanelBarChart.setOption(channelBarOption);
}, 25000);
六、月每端销售数据占比
代码如下：
// 图二、饼图，按客户端类型显示销售额
function genChannelPieOption(salesData) {
return {
color: ['#6f85ff', '#66ffff', '#4fc0f5'],
tooltip: {
trigger: 'item',

itemStyle: {
normal: {
label: {
show: true,
formatter: '{d}%\n\n{b} ',
textStyle: {
fontSize: 18,
fontWeight: 'bold'
},
},
labelLine: { show: true }
}
}
}
]
};
}
var channelPieOption = genChannelPieOption(salesData);
var chanelPieChart = echarts.init(document.getElementById('channel_pie'));
chanelPieChart.setOption(channelPieOption);
// 基于准备好的dom，初始化echarts实例
setInterval(function () {
chanelPieChart.dispose();
$("#channel_pie").html("");
chanelPieChart = echarts.init(document.getElementById('channel_pie'));
chanelPieChart.setOption(channelPieOption);
}, 21000);
七、商品每日销售数据
代码如下：
//商品日销售趋势
$(function () {
var dateArr = ['06.12', '06.13', '06.14', '06.15', '06.16', '06.17', '06.18', '06.19', '06.20', '06.21', '06.22', '06.23', '06.24', '06.25', '06.26'],
