## 2.1 环境准备
flexible.js+rem 智能大屏适配
flexible 是阿里出品的屏幕适配。
~~~bash
https://github.com/amfe/lib-flexible
~~~
引用js的话
~~~bash
https://github.com/amfe/lib-flexible/blob/2.0/index.js
~~~
具体例子
~~~js
(function flexible(window, document) {
var docEl = document.documentElement;
var dpr = window.devicePixelRatio || 1;
// adjust body font size
function setBodyFontSize() {
if (document.body) {
document.body.style.fontSize = 12 * dpr + "px";
} else {
document.addEventListener("DOMContentLoaded", setBodyFontSize);
}
}
setBodyFontSize();
// set 1rem = viewWidth / 10
function setRemUnit() {
var rem = docEl.clientWidth / 24;
docEl.style.fontSize = rem + "px";
}
setRemUnit();
// reset rem unit on page resize
window.addEventListener("resize", setRemUnit);
window.addEventListener("pageshow", function(e) {
if (e.persisted) {
setRemUnit();
}
});
// detect 0.5px supports
if (dpr >= 2) {
var fakeBody = document.createElement("body");
var testElement = document.createElement("div");
testElement.style.border = ".5px solid transparent";
fakeBody.appendChild(testElement);
docEl.appendChild(fakeBody);
if (testElement.offsetHeight === 1) {
docEl.classList.add("hairlines");
}
docEl.removeChild(fakeBody);
}
})(window, document);
~~~
vscode cssrem插件
flex 布局
less 使用
把less 编译成css插件
## 2.2 入门demo
### 基础设置
flexible.js
~~~javascript
(function flexible(window, document) {
var docEl = document.documentElement;
var dpr = window.devicePixelRatio || 1;
// adjust body font size
function setBodyFontSize() {
if (document.body) {
document.body.style.fontSize = 12 * dpr + "px";
} else {
document.addEventListener("DOMContentLoaded", setBodyFontSize);
}
}
setBodyFontSize();
// set 1rem = viewWidth / 10
function setRemUnit() {
var rem = docEl.clientWidth / 24;
docEl.style.fontSize = rem + "px";
}
setRemUnit();
// reset rem unit on page resize
window.addEventListener("resize", setRemUnit);
window.addEventListener("pageshow", function(e) {
if (e.persisted) {
setRemUnit();
}
});
// detect 0.5px supports
if (dpr >= 2) {
var fakeBody = document.createElement("body");
var testElement = document.createElement("div");
testElement.style.border = ".5px solid transparent";
fakeBody.appendChild(testElement);
docEl.appendChild(fakeBody);
if (testElement.offsetHeight === 1) {
docEl.classList.add("hairlines");
}
docEl.removeChild(fakeBody);
}
})(window, document);

## 3.1 配置项讲解
全部的配置项网址
~~~bash
https://echarts.apache.org/zh/option.html#title
~~~
| 配置名 | 作用 |
| ------- | ------------------------------------------------------------ |
| title | 设置图表的标题 |
| tooltip | 图表提示框组件 |
| trigger | 触发方式 |
| legend | 图例组件 |
| grid | 网格配置，图表不一样和容器一样大。可以控制线性图的大小 |
| toolbox | 工具箱 |
| xAxis | X 轴 |
| yAxis | Y 轴 |
| series | 系列图表配置，显示那种配置信息，其中type 信息决定了图的类型，pie 为饼图，line 折线图，bar 为柱状图 |
| color | 设置线条颜色，是数组 |
| | |
| | |
## 3.2 柱状图
引入相关js
~~~javascript
// ()(); 这个是立即执行函数
(function() {

tooltip: {
// 这个是提示框信息
trigger: "axis",
// 坐标轴触发，主要在柱状图，折线图等会使用类目轴的图表中使用。
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'
},
},
// 修改图表的大小
grid: {
left: "0%",
top: "10px",
right: "0%",
bottom: "4%",
containLabel: true,
},
// 坐标轴信息
xAxis: [{
type: "category",
data: [
"旅游行业",
"教育培训",
"游戏行业",
"医疗行业",
"电商行业",
"社交行业",
"金融行业",
],
axisTick: {
alignWithLabel: true,
},
// 修改刻度标签相关样式
axisLabel: {
color: "rgba(255, 255, 255, .6)",
fontSize: "12",
interval: 0, //控制是否全部显示
},
// 不显示x轴的样式
axisLine: {

// y轴坐标系
axisLine: {
lineStyle: {
color: "rgba(255, 255, 255, .1)",
width: 2,
},
},
// y轴分割线的颜色
splitLine: {
lineStyle: {
color: "rgba(255, 255, 255, .1)",
},
},
}, ],
series: [{
name: "直接访问",
type: "bar",
// 修改柱子的宽度
barWidth: "35%",
data: [200, 300, 300, 900, 1500, 1200, 600],
itemStyle: {
// 修改柱子的圆角
