使用zrender.js绘制体温单(2)
今天我们来画折线图 效果图
以下为模拟数据

首先创建filterData方法 用于过滤数据 text文本 line线段 area圆 tag暂时用不到 今天说的是折线所以创建zrLine 方法
filterData(){
const data = chartData
data.forEach(el => {
switch (el.type) {
case "text":
// this.zrText(el)
break;
case "line":
this.zrLine(el)
break;
case "area":
this.zrPolyline(el)
break;
case "tag":
this.zrTag(el)
break;
default:
break;
}
});
}
utli.js 我们先说 createLine createCircle
createLine 需要传5个参数分别为开始点的横纵坐标 结束点的横纵坐标 还有线的样式
createCircle 需要传4个参数分别为 圆点的横纵坐标 圆的半径 和样式
addHover 也需要 这时我们需要在init 方法里添加一段代码(上一章创建的初始化方法) 这段代码为创建一个div到时我们鼠标移到圆上会弹出文本信息的时候回用到
var div = document.createElement("div")
div.classList.add("tips")
document.getElementById("main").append(div)
utli.js
//线段
export const createLine = (x1,y1,x2,y2,style)=>{
return new zrender.Line({
shape:{
x1:x1,
y1:y1,
x2:x2,
y2:y2
},
style:style,
});
};
// cx 横坐标 cy纵坐标 r半径 空心圆
export const createCircle = (cx,cy,r,style)=>{
return new zrender.Circle({
shape:{
cx:cx,
cy:cy,
r:r
},
style:style,
zlevel:4
})
}
//添加horver事件 el 元素对象 config 一些配置项 x x轴坐标 y y轴坐标 shapeOn鼠标移入一些属性配置 shapeOn鼠标移出一些属性配置 shape配置项看官网
export const addHover = (el,config,x,y,shapeOn,shapeOut) => {
const domTips = document.getElementsByClassName("tips")
el.on('mouseover',function(){
domTips[0].innerHTML = config.tips
domTips[0].setAttribute("style",`position:absolute;top:${y-13}px;left:${x}px;display:block;font-size:10px;background-color:rgba(0,0,0,.7);padding:3px;border-radius:3px;color:#fff`)
el.animateTo({
shape:shapeOn
},100,0)
}).on('mouseout',function () {
domTips[0].setAttribute("style",`display:none`)
el.animateTo({
shape:shapeOut
},100,0)
})
}
//多边形
export const createPolygon = (points,style) => {
return new zrender.Polyline({
shape:{
points:points,
},
style:style
})
}
var style = {}
switch (data.shape) {
case "x-circle":
style = {
stroke:data.color,
fill:"#fff",
text:"x",
}
break;
case "empty-circle":
style = {
stroke:data.color,
fill:"#fff",
text:"",
}
break;
default:
break;
}
这里需要在添加2个方法
//获取X坐标 data当前时间点
getX(data){
let XShareOne = this.XShareOne()
return data * XShareOne
},
//转换y轴坐标点为正确坐标点 因为y轴坐标是顶点为0递增的 所有用总高度减去原来坐标的高度剩下的高度就是正确坐标点
//i代表一个格子代表几个高度
transformY(data,i){
let YHeight = this.YShareOne()
//计算出剩余高度
let surplusHeight = this.canavsHeight - (YHeight/i) * data
return surplusHeight
},
这段代码意思是先把数据遍历出来 在通过time属性计算出x坐标 value值计算出y坐标 x轴左边基本是以time为基本来计算的 y轴坐标可能会随数据变化而有所改变 Break属性为是否断线 如果需要断线就位true
data.array.forEach((el,i) =>{
if (i > 0) {
let XShareOne = this.XShareOne()
let firstX = this.getX(data.array[i-1].time)
let firstY = this.transformY(data.array[i-1].value,1)
let x = this.getX(data.array[i].time)
let y = this.transformY(data.array[i].value,1)
if (data.array[i-1].Break == "false") {
let line = createLine(firstX,firstY,x,y,{
stroke:"#af2377",
lineWidth:2,
})
this.zr.add(line)
}
}
if (el.extraArr && el.extraArr.length > 0) {
el.extraArr.forEach((item,a) => {
let x = this.getX(el.time)
let y = this.transformY(el.value,1)
let lastY = this.transformY(item.extra,1)
let dottedLine = createLine(x,y,x,lastY,{
stroke:"#af2377",
lineWidth:2,
lineDash:[2,2]
})
this.zr.add(dottedLine)
el.extraArr.forEach((item,a) => {
let getY = this.transformY(item.extra,1)
let Circle = createCircle(x,getY,5,{
stroke:item.extraColor,
fill:"#fff",
})
this.zr.add(Circle)
addHover(Circle,{
tips:item.extraTips,
},x,getY,{
r:8,
},{
r:5,
})
})
})
}
let getX = this.getX(el.time)
let getY = this.transformY(el.value,1)
let Circle = createCircle(getX,getY,5,style)
this.zr.add(Circle)
addHover(Circle,el,getX,getY,{
r:8,
},{
r:5,
})
})
这步完成折线图应该就画好了
下次我们讲阴影的画法
