最近做可视化比较多,就常用的图表类型做了一下总结。
因为做可视化的图表代码量非常大,所以会把echarts图表单独抽离出来,封装成一个组件,也可以复用,所以这里我直接把封装的组件直接放在这里,是可以直接拿来用的,根据所需稍作修改即可。
这里都是用的vue3,其实和vue2差不多,在写法上稍作修改即可。
其中用到了一个 fontChart 的方法,这样是为了在window变化(改变缩放)的时候能够让字体也达到自适应,因为默认的单位是px,如果不使用的话,当我们去减小屏幕缩放的时候,这时候屏幕分辨率就会变大,但是我们的字体还是xxpx,就会让我们的字体看上去特别小,所以这里使用了这个方法,fontChart方法如下:
scr/utils/echartPxToRem.js
export function fontChart(res) {
let docEl = document.documentElement,
clientWidth =
window.innerWidth ||
document.documentElement.clientWidth ||
document.body.clientWidth;
if (!clientWidth) return;
// 此处的3840 为设计稿的宽度,记得修改!
let fontSize = clientWidth / 1920;
return res * fontSize;
}
接下来正题:
第一步首先安装 highcharts
npm install highcharts --save
第二步 main.js 引入 3d相关
import highcharts from 'highcharts'
import highcharts3d from 'highcharts/highcharts-3d'
highcharts3d(highcharts)
然后封装成组件
一. 3D饼图

["压风", 4],
]),
},
});
watch(
() => props.pieData,
(newValue) => {
initOption();
},
{
deep: true,

);
onMounted(() => {
initOption();
window.addEventListener("resize", initOption);

onUnmounted(() => {
window.removeEventListener("resize", initOption);
});
// 初始化echarts
