jquery实现柱形图、饼图等

主要是添加label来实现在图形上显示对于的数据
饼图显示数据：
option1 = {
            title: {
                text: ‘学历统计‘,
                subtext: ‘‘,
                x: ‘center‘
            },
            tooltip: {
                trigger: ‘item‘,
                formatter: "{a} <br/>{b} : {c} ({d}%)"
            },
            legend: {
                orient: ‘vertical‘,
                left: ‘left‘,
                data: []
            },
            series: [
                {
                    name: ‘‘,
                    type: ‘pie‘,
                    radius: ‘55%‘,
                    center: [‘50%‘, ‘60%‘],
                    label: {//在圆内显示具体数据数字
                        normal: {
                            formatter: ‘{b}:{d}%‘,
                            position: ‘inside‘
                        }
                    },
                    data: [],
                    itemStyle: {
                        emphasis: {
                            shadowBlur: 10,
                            shadowOffsetX: 0,
                            shadowColor: ‘rgba(0, 0, 0, 0.5)‘
                        }
                    }
                }
            ]
        };
        
        
柱形图：

  option = {
            title: {
                text: ‘人数统计‘
            },
            color: [‘#749f83‘],
            tooltip: {},
            legend: {
                data: [‘人数‘]
            },
            xAxis: {
                data: []
            },
            yAxis: {},
            series: [{
                name: ‘人数‘,
                type: ‘bar‘,
                label: {
                    normal: {
                        position: ‘top‘,
                        show: true
                    }
                },
                data: []
            }]
        };
