应对现在数据可视化的趋势,越来越多企业需要在很多场景(营销数据,生产数据,用户数据)下使用,可视化图表来展示体现数据,让数据更加直观,数据特点更加突出。
完成该项目需要具备以下知识:
设计稿是1920px
flexible.js 把屏幕分为 24 等份
cssrem 插件的基准值是 80px
插件-配置按钮—配置扩展设置–Root Font Size 里面 设置。
但是别忘记重启vscode软件保证生效

常见的数据可视化库:
ECharts,一个使用 JavaScript 实现的开源可视化库,可以流畅的运行在 PC 和移动设备上,兼容当前绝大部分浏览器(IE8/9/10/11,Chrome,Firefox,Safari等),底层依赖矢量图形库 ZRender,提供直观,交互丰富,可高度个性化定制的数据可视化图表。
大白话:
官网地址:https://www.echartsjs.com/zh/index.html
官方教程:五分钟上手ECharts
使用步骤:
<div id="main" style="width: 600px;height:400px;">div>
var myChart = echarts.init(document.getElementById('main'));
var option = {
xAxis: {
type: 'category',
data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
},
yAxis: {
type: 'value'
},
series: [{
data: [820, 932, 901, 934, 1290, 1330, 1320],
type: 'line'
}]
};
myChart.setOption(option);
这是要求同学们知道以下配置每个模块的主要作用干什么的就可以了
需要了解的主要配置:
series
xAxis
yAxis
grid
tooltip
title
legend
color
series
type
决定自己的图表类型xAxis:直角坐标系 grid 中的 x 轴
yAxis:直角坐标系 grid 中的 y 轴
grid:直角坐标系内绘图网格。
title:标题组件
tooltip:提示框组件
legend:图例组件
color:调色盘颜色列表
数据堆叠,同个类目轴上系列配置相同的stack
值后 后一个系列的值会在前一个系列的值上相加。
option = {
// color设置我们线条的颜色 注意后面是个数组
color: ['pink', 'red', 'green', 'skyblue'],
// 设置图表的标题
title: {
text: '折线图堆叠123'
},
// 图表的提示框组件
tooltip: {
// 触发方式
trigger: 'axis'
},
// 图例组件
legend: {
// series里面有了 name值则 legend里面的data可以删掉
},
// 网格配置 grid可以控制线形图 柱状图 图表大小
grid: {
left: '3%',
right: '4%',
bottom: '3%',
// 是否显示刻度标签 如果是true 就显示 否则反之
containLabel: true
},
// 工具箱组件 可以另存为图片等功能
toolbox: {
feature: {
saveAsImage: {}
}
},
// 设置x轴的相关配置
xAxis: {
type: 'category',
// 是否让我们的线条和坐标轴有缝隙
boundaryGap: false,
data: ['星期一', '周二', '周三', '周四', '周五', '周六', '周日']
},
// 设置y轴的相关配置
yAxis: {
type: 'value'
},
// 系列图表配置 它决定着显示那种类型的图表
series: [
{
name: '邮件营销',
type: 'line',
data: [120, 132, 101, 134, 90, 230, 210]
},

name: '直接访问',
type: 'line',
data: [320, 332, 301, 334, 390, 330, 320]
}
]
};
// 柱状图1模块
(function() {
// 实例化对象
let myChart = echarts.init(document.querySelector(".bar .chart"));
// 指定配置和数据
let option = {
color: ["#3398DB"],
tooltip: {
trigger: "axis",
axisPointer: {
// 坐标轴指示器,坐标轴触发有效
type: "shadow" // 默认为直线,可选为:'line' | 'shadow'
}
},
grid: {
left: "3%",
right: "4%",
bottom: "3%",
containLabel: true
},
xAxis: [
{
type: "category",
data: ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"],
axisTick: {
alignWithLabel: true
}
}
],
yAxis: [
{
type: "value"
}
],
series: [
{
name: "直接访问",
type: "bar",
barWidth: "60%",
data: [10, 52, 200, 334, 390, 330, 220]
}
]
};
// 把配置给实例对象
myChart.setOption(option);
})();
根据需求定制
修改图表柱形颜色 #2f89cf

需求1: 更换图例组件文字颜色 rgba(255,255,255,.5) 文字大小为12
legend: {
top: "0%",
textStyle: {
color: "rgba(255,255,255,.5)",

axisLabel: {
textStyle: {
color: "rgba(255,255,255,.6)",
fontSize: 12
}

fontSize: 12
}
},
// 修改分割线的颜色
splitLine: {

需求5: 修改两个线模块配置(注意在series 里面定制)
//第一条 线是圆滑
smooth: true,
// 单独修改线的样式
lineStyle: {
color: "#0184d5",
width: 2
},
// 填充区域
areaStyle: {
// 渐变色,只需要复制即可

0,
0,
0,
1,
[
{
offset: 0,
color: "rgba(1, 132, 213, 0.4)" // 渐变色的起始颜色
},
{
offset: 0.8,
color: "rgba(1, 132, 213, 0.1)" // 渐变线的结束颜色
}
],
false
),
shadowColor: "rgba(0, 0, 0, 0.1)"

// 设置拐点 小圆点
symbol: "circle",
// 拐点大小

itemStyle: {
color: "#0184d5",
borderColor: "rgba(221, 220, 107, .1)",
borderWidth: 12
},
// 开始不显示拐点, 鼠标经过显示
showSymbol: false,
name: "转发量",
type: "line",
smooth: true,
lineStyle: {
normal: {
color: "#00d887",
width: 2

0,
0,
0,
1,
[
{
offset: 0,
color: "rgba(0, 216, 135, 0.4)"
},
{
offset: 0.8,
color: "rgba(0, 216, 135, 0.1)"
}
],
false
),
shadowColor: "rgba(0, 0, 0, 0.1)"
}
},
// 设置拐点 小圆点
symbol: "circle",
// 拐点大小
symbolSize: 5,
// 设置拐点颜色以及边框
itemStyle: {
color: "#00d887",
borderColor: "rgba(221, 220, 107, .1)",
borderWidth: 12
},
// 开始不显示拐点, 鼠标经过显示
showSymbol: false,
需求6: 更换数据
// x轴更换数据
data: [ "01","02","03","04","05","06","07","08","09","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25","26","26","28","29","30"],
// series 第一个对象data数据
data: [ 30, 40, 30, 40,30, 40, 30,60,20, 40, 30, 40, 30, 40,30, 40, 30,60,20, 40, 30, 40, 30, 40,30, 40, 20,60,50, 40],
// series 第二个对象data数据
data: [ 130, 10, 20, 40,30, 40, 80,60,20, 40, 90, 40,20, 140,30, 40, 130,20,20, 40, 80, 70, 30, 40,30, 120, 20,99,50, 20],
定制图表需求1:
legend: {
// 距离底部为0%
bottom: "0%",
// 小图标的宽度和高度
itemWidth: 10,
itemHeight: 10,
data: ['直接访问', '邮件营销', '联盟广告', '视频广告', '搜索引擎'],
// 修改图例组件的文字为 12px
textStyle: {
color: "rgba(255,255,255,.5)",
fontSize: "12"
}
},
定制需求2:
series: [
{
name: "年龄分布",
type: "pie",
// 设置饼形图在容器中的位置
center: ["50%", "50%"],
// 修改内圆半径和外圆半径为 百分比是相对于容器宽度来说的
radius: ["40%", "60%"],
// 不显示标签文字
label: { show: false },
// 不显示连接线
labelLine: { show: false },
}
]
定制需求3:更换数据
// legend 中的data 可省略
data: ["0岁以下", "20-29岁", "30-39岁", "40-49岁", "50岁以上"],
// series 中的数据
data: [
{ value: 1, name: "0岁以下" },
{ value: 4, name: "20-29岁" },
{ value: 2, name: "30-39岁" },
{ value: 2, name: "40-49岁" },
{ value: 1, name: "50岁以上" }
] ,
定制需求4: 更换颜色
color: [
"#065aab",
"#066eab",
"#0682ab",
"#0696ab",
"#06a0ab",
],
// 4. 让图表跟随屏幕自动的去适应
window.addEventListener("resize", function() {
myChart.resize();
});
第二步:按照需求定制
color: ['#006cff', '#60cda0', '#ed8884', '#ff9f7f', '#0096ff', '#9fe6b8', '#32c5e9', '#1d9dff'],
radius: ['10%', '70%'],
roseType: "radius",
{ value: 20, name: '云南' },
{ value: 26, name: '北京' },
{ value: 24, name: '山东' },
{ value: 25, name: '河北' },
{ value: 20, name: '江苏' },
{ value: 25, name: '浙江' },
{ value: 30, name: '四川' },
{ value: 42, name: '湖北' }
需求5:字体略小些 10 px ( series对象里面设置 )
饼图图形上的文本标签可以控制饼形图的文字的一些样式。 label 对象设置
series: [
{
name: "面积模式",
type: "pie",
radius: [30, 110],
center: ["50%", "50%"],
roseType: "radius",
// 文本标签控制饼形图文字的相关样式, 注意它是一个对象
label: {
fontSize: 10
},
}
]
};
+ // 文字调整
+ label:{
+ fontSize: 10
+ },
+ // 引导线调整
+ labelLine: {
+ // 连接扇形图线长
+ length: 6,
+ // 连接文字线长
+ length2: 8
+ }
+ }
+ ],
// 监听浏览器缩放,图表对象调用缩放resize函数
window.addEventListener("resize", function() {
myChart.resize();
});
社区就是一些,活跃的echart使用者,交流和贡献定制好的图表的地方。
参考社区的例子:https://gallery.echartsjs.com/editor.html?c=x0-ExSkZDM (模拟飞机航线)
实现步骤:
需要修改:
geo: {
map: 'china',
zoom: 1.2,
label: {
emphasis: {
show: false
}
},
roam: false,
itemStyle: {
normal: {
areaColor: '#142957',
borderColor: '#0692a4'
},
emphasis: {
areaColor: '#0b1c2d'
}
}
},
总结:这例子是扩展案例,大家以后可以多看看社区里面的案例。
