echarts图通用常用配置---图例和背景图配置
1.图表的图例
这个一个饼状环形图,右侧的部分叫做--图例,在很长一段时间我把它叫做标签,导致出现问题百度都找不到对应的问题点😢。 还有今天才知道echarts还可以使用图片给它加背景图。下面代码内容有加图片背景和给环形图设置外围圆环,还有图例的常用配置项😍
orderPie(data) {
let option = {
//这里是关于图片的配置
graphic: [
{
type: "image", // 图形元素类型
id: "logo", // 更新或删除图形元素时指定更新哪个图形元素,如果不需要用可以忽略。
right: "right", // 根据父元素进行定位 (居中)
bottom: "20%", // 根据父元素进行定位 (0%), 如果bottom的值是 0,也可以删除该bottom属性值。
left: "70%",
z: 0, // 层叠
bounding: "all", // 决定此图形元素在定位时,对自身的包围盒计算方式
style: {
// image: "../../../assets/images/projectShi/huantu.png", // 这里一定要注意、注意,必须是https开头的图片路径地址
// image: "https://www.boxuegu.com/assets/user/background1.png",
