条形图，想给坐标加图片echarts 柱状配置项内容和展示

目前用的markPoint 设置为图片，但是图片里面会显示 xaxis的值，如何可以不显示该值，见图片中的 数字 1 ；或者其他更好的实现方法也可以。

      var i = -1;
option = {
    tooltip: {
        trigger: 'axis',
        axisPointer: {
            type: 'shadow'
        }
    },
    grid: {
        left: '3%',
        right: '3%',
        bottom: '3%',
        containLabel: true
    },
    xAxis: {
        show:false,
        type: 'value'
    },
    yAxis: {
        show: true,
        type: 'category',
        data: ['AAA','BBB','CCC','DDD','EEE'],
        axisLine:{
            show:false
        },
        axisTick:{
            show:false
        },
        axisLabel:{
            margin:120,
            textStyle:{
                color:'#000000',
                fontSize:20
            }
        }
    },
    series: [
        {
            name: '出库数量',
            type: 'bar',
            data: [19,42,64,75, 88],
            label: {
                normal: {
                    show: true,
                    position: 'right',
                    textStyle: {
                        color:'black',
                        fontSize: '30',
                        fontWeight: 'bold'
                    }
                }
            },
            markPoint: {
                    data: [
                        { name: '2', xAxis: 1, yAxis: 0, symbol: 'image:// http://localhost:61361/Content/images/yinshua_34.png', symbolSize: [80,100],symbolOffset:['-180%','0%'] },
                        { name: '2', xAxis: 1, yAxis: 1, symbol: 'image:// http://localhost:61361/Content/images/yinshua_30.png', symbolSize: [80,100],symbolOffset:['-180%','0%'] },
                        { name: '2', xAxis: 1, yAxis: 2, symbol: 'image:// http://localhost:61361/Content/images/yinshua_28.png', symbolSize: [80,100],symbolOffset:['-180%','0%'] },

                        { name: '2', xAxis: 1, yAxis: 4, symbol: 'image:// http://localhost:61361/Content/images/yinshua_12.png', symbolSize: [80,100],symbolOffset:['-180%','0%'] }
                    ]
                 },
			itemStyle:{
				normal:{
					color:function(param){
					    i++;
					    var colorList = ['#FFDB0D','#40BFA4','#FFDB0D','#40BFA4','#FFDB0D','#40BFA4'];
					    return colorList[i]
