echarts折线设置不同颜⾊，且做线段标记前⾔：项⽬需要，需要画⼀段数据的折线图，折线图根据正常数据和异常数据显⽰两种颜⾊的线，并且在⿏标经过异常线横坐标时，标记该点往后的⼗个点组成的线，标记可以有很多⽅式: 1,第⼀个点和最后⼀个点做标记markPoint,2,第⼀个点到第⼗个点做区域阴影markArea，3，第⼀个点和第⼗个点都变颜⾊......等，反应这⼀段线就可以，我这⾥是选择的第⼆种⽅式，效果图：代码如下： Echarts.vue⽂件（写了⼀个echarts的组件）html部分<template><div :id="id"></div></template>js部分<script>import echarts from 'echarts'import chinaJSON from '@/assets/data/chinaMap.json'echarts.registerMap('china', chinaJSON)export default {data () {return {chart: null,n: 0}},props: ['id', 'option'],mounted () {let vm = thisthis.chart = echarts.init(document.getElementById(this.id))let baseOption = {}let options = Object.assign({}, baseOption, this.option)this.chart.setOption(options, {notMerge:true,})// 以下为echarts的各种⽅法，我这⾥只使⽤了datazoom，和updateAxisPointer⽅法。

⼀起来玩echarts系列（⼀）------箱线图的分析与绘制#⼀、箱线图 Box-plot箱线图⼀般被⽤作显⽰数据分散情况。

具体是计算⼀组数据的`中位数`、`25%分位数`、`75%分位数`、`上边界`、`下边界`，来将数据从⼤到⼩排列，直观展⽰数据整体的分布情况。

 ⼤部分正常数据在箱体中，上下边界之外的就是异常数据了。

上下边界的计算公式是：UpperLimit=Q3+1.5IQR=75%分位数+（75%分位数-25%分位数）1.5LowerLimit=Q1－1.5IQR=25%分位数-（75%分位数-25%分位数）1.5参数说明：1.Q1表⽰下四分位数，即25%分位数；Q3为上四分位数，即75%分位数；IQR表⽰上下四分位差，系数1.5是⼀种经过⼤量分析和经验积累起来的标准，⼀般情况下不做调整。

2.分位数的参数可根据具体预警结果调整：25%和75%，是⽐较灵敏的条件，在这种条件下，多达25%的数据可以变得任意远⽽不会很⼤地扰动四分位。

具体业务中可结合拟合结果⾃⾏调整为其他分位使⽤echarts时，这些计算通过调⽤echarts.dataTool.prepareBoxplotData()来完成。

说到这⾥，有⼀个预警，绘制箱线图除了要下载echart.js之外，还需要引⼊dataTool.js，否则浏览器会报错：Uncaught TypeError: Cannot read property 'prepareBoxplotData' of undefined(…)。

dataTool.js可以到上下载。

#⼆、echarts箱线图⽰例echart官⽹给出的**[箱线图⽰例](/demo.html#boxplot-light-velocity)**有两种。

⼀种是单值对应（样本元素有⼀组对应的值数据）：另⼀种是多值对应（样本元素有多个对应的值数据）：#三、数据结构分析###1.单值对应单值对应的数据结构⽐较简单，⼀个样本信息的数据存储到对应的⼀个数组⾥，这些数组⼜存储在⼀个⼤数组⾥。

eCharts标域markArea分区域显⽰不同颜⾊需求：利⽤eCharts做⼀个数据折线图，分为等待数量和请求数量百分⽐= 等待数量/请求数量（四舍五⼊，截取两位有效数字）0% < 百分⽐ <= 50% 标域显⽰绿⾊50% < 百分⽐ <100% 标域显⽰黄⾊百分⽐ >= 100% 标域显⽰红⾊下⾯展⽰部分关键代码：先声明两个数组：1//存储百分⽐2var percent = new Array();3//存储标域根据百分⽐划分要显⽰的颜⾊和位置4var markData= new Array();此部分为eCharts数据展⽰1 series : [{2 name:'请求量',3 type:'line',4 markArea : {5 data:markData6 }7 }]接下来做数据判断划分相应百分⽐的颜⾊和显⽰的位置getPercent();存储百分⽐得到，percent（四舍五⼊，截取两位有效数字）,此⽅法在这⾥不是关键，所以不做展⽰了 1function getMarkData(index,colors) {2var data = [{3 xAxis: index,4 yAxis:0,5 itemStyle:{6 color: colors7 }8 },{9 xAxis: index + 1;10 }];11 markData.push(data);12 }1314function markArea(){15//⽤于获取百分⽐16 getPercent();17for(var i = 0 ; i < percent.length ; i++){18if(percent[i] > 0 && percent[i] <= 0.5){19 getMarkData(i,'green');20 }else if(percent[i] >= 1){21 getMarkData(i,'red');22 }else if(percent[i] > 0.5 && percent[i] < 1){23 getMarkData(i,'yellow');24 }else{25 getMarkData(i,'white');26 }27 }28 }最后直接调⽤就可以了。

第24卷第1期沙洲职业工学院学报Vol.24,No.1 2021年3月Journal of Shazhou Professional Institute of Technology March,2021基于ECharts的数据可视化应用周洪斌陈立平刘连浩（沙洲职业工学院，江苏张家港215600）摘要：数据可视化已成为大数据分析的主要环节之一。

ECharts因其具备丰富的可视化类型以及高度的个性化定制功能，被众多机构和企业使用。

pyecharts是一款将Python与ECharts结合的强大的数据可视化工具，使数据呈现更加快捷、灵活、高效。

借助pyecharts实现了城市各监测点的PM2.5数据的自动爬取以及可视化展示，对开展其他的大数据可视化应用具有借鉴作用。

关键词：ECharts；pyecharts；数据可视化中图分类号：TP311.13文献标识码：A文章编号：1009－8429(2021)01－0003－07引言数据是枯燥、抽象的，而图形、图像却富有表现力和生动性。

数据可视化将各种数据用图形化的方式展示，为数据分析提供了更加直观的显示方式[1]，是人们理解数据、诠释数据的重要手段和途径。

ECharts是国内百度公司推出的一款开源大数据可视化工具[2]，具备千亿级数据可视化渲染能力，支持折线图、饼图、热力图、漏斗图、词云图等丰富的可视化类型，支持二维表、键值对等多种数据格式，并且具有数据的动画展示、三维展示功能，已在国家统计局、国家电网、阿里巴巴、华为等众多机构和企业使用。

2018年，全球顶级开源社区Apache基金会宣布“百度开源的ECharts项目全票通过进入Apache孵化器”，ECharts发展进入快车道。

1ECharts使用基础1.1引用echarts.jsECharts由JavaScript实现，使用非常方便，从官网https:///zh/download.html 下载安装包，解压得到echarts.js文件，与HTML文件放到同一目录下，在HTML文件中通过下面的代码引用echarts.js文件，即可使用ECharts。

qchart曲线点标注字符QChart是Qt框架中的图表库，用于绘制各种图表，包括曲线图。

在曲线图中，标注字符的功能是十分重要的，它可以帮助用户更清晰地理解图表中的数据点。

本文将详细介绍在QChart中如何进行曲线点的标注字符，包括基本设置、自定义标注、以及一些实用的技巧。

QChart曲线点标注的基本设置在QChart中，通过QLineSeries类可以很容易地绘制曲线图。

标注曲线上的点可以通过QScatterSeries类实现。

以下是一个基本的设置过程：#include <QtWidgets/QApplication>#include <QtCharts/QChart>#include <QtCharts/QLineSeries>#include <QtCharts/QScatterSeries>#include <QtCharts/QChartView>QT_CHARTS_USE_NAMESPACEint main(int argc,char*argv[]){QApplication a(argc,argv);QChart *chart =new QChart();QLineSeries *series =new QLineSeries();QScatterSeries *scatterSeries =new QScatterSeries();// 添加数据点series->append(0,1);series->append(1,2);series->append(2,3);series->append(3,4);// 设置曲线chart->addSeries(series);// 设置标注字符scatterSeries->setMarkerShape(QScatterSeries::MarkerShapeCircle); scatterSeries->setMarkerSize(10);// 将标注字符添加到曲线上for(int i =0;i <series->count();++i){scatterSeries->append(series->at(i));scatterSeries->setPointLabelsVisible(true);scatterSeries->setPointLabelsFormat("@yPoint");// @yPoint表示使用y坐标作为标注字符}// 将标注字符的颜色与曲线颜色一致scatterSeries->setColor(series->color());// 将标注字符添加到图表中chart->addSeries(scatterSeries);// 创建图表视图QChartView *chartView =new QChartView(chart);chartView->setRenderHint(QPainter::Antialiasing);// 显示图表视图chartView->show();return a.exec();}上述代码中，通过QScatterSeries实现了标注字符的添加。
