0x00 Antv G2的繪圖流程
1.引入js庫
<script src="https://cdn.bootcdn.net/ajax/libs/g2plot/1.2.0-beta.0/g2plot.js"></script>
2.準備渲染容器DOM
<div id='g2-chart'></div>
3.準備渲染數據
const data =[
{year:'1991',value:3},
{year:'1992',value:4},
{year:'1993',value:7},
{year:'1994',value:5},
{year:'1995',value:6}
];
4.獲取渲染DOM對象
const chartDom = document.getElementById('g2-chart');
5.初始化G2繪圖對象，配置繪圖參數
const line = new G2Plot.Line(chartDom,{
title:{
visible:true,
text:'g2折線圖實例'
},
description:{
visible:true,
text:'這是一個副標題'
},
data:data,
xField:'year',
yField:'value',
point:{
visible:true,
size:5,
color:'#fff',
style:{
stroke:'#fe740c',//邊框顏色
lineWidth:2,
fillOpacity:0.6
}
},
label:{
visible:true
},
color:'#f2740c',//線條的顏色
yAxis:{
formatter:function(v){
return v+'k';
}
}
});
6.調用render完成渲染
line.render();
