1.知识点

主动触发echarts高亮等
https://blog.youkuaiyun.com/m0_52545254/article/details/135502912
1).Echarts中图例(legend)使用自定义图标legned部分代码：

legend:{
        show: true,
        data:[
            {
                name:'xxx',
                icon:"image://图片路径"
            },
        ],
    },

注：vue项目中图片必须放在public文件夹下，可以在public下创建一个文件夹存放图片
2).数据X轴名字太长处理方案

倾斜

	xAxis:{
		axisLabel: {
            interval:0,//0取消超长隔行显示
            rotate:30,//倾斜属性
        },
	}

设置一行显示几个字，超出换行居中显示

	xAxis:{
		axisLabel: {
            formatter:function(params) {
                let newParamsName = ''; // 最终拼接成的字符串
                let paramsNameNumber = params.length; // 实际标签的个数
                let provideNumber = 8; // 每行能显示的字的个数
                let rowNumber = Math.ceil(paramsNameNumber / provideNumber); // 换行的话，需要显示几行，向上取整
                /**
            * 判断标签的个数是否大于规定的个数， 如果大于，则进行换行处理 如果不大于，即等于或小于，就返回原标签
            */
                // 条件等同于rowNumber>1
                if (paramsNameNumber > provideNumber) {
                    /** 循环每一行,p表示行 */
                    for (let p = 0; p < rowNumber; p++) {
                        let tempStr = ''; // 表示每一次截取的字符串
                        let start = p * provideNumber; // 开始截取的位置
                        let end = start + provideNumber; // 结束截取的位置
                        // 此处特殊处理最后一行的索引值
                        if (p === rowNumber - 1) {
                            // 最后一次不换行
                            tempStr = params.substring(start, paramsNameNumber);
                        } else {
                            // 每一次拼接字符串并换行
                            tempStr = params.substring(start, end) + '\n';
                        }
                        newParamsName += tempStr; // 最终拼成的字符串
                    }
                    //超出2行显示...
                    //if(rowNumber>2){
                            //  newParamsName+='...'
                            //}		

                } else {
                    // 将旧标签的值赋给新标签
                    newParamsName = params;
                }
                //将最终的字符串返回
                return newParamsName
            }
        },
	}

设置显示字数，超出显示…，鼠标移入显示全
