如何将 y 轴上的刻度长度设置为 0 或从 highchart 中的 y 轴上删除刻度线?

How to set tick length in y-axis to 0 or remove tickline from y axis in highchart?

x 轴 'tickLength: 0' 正在工作,我可以从 x 轴标签上删除勾号,但同样的事情不适用于 y 轴。请建议我删除 y 轴刻度线的正确方法。

$(function () {
Highcharts.setOptions({
    colors: ['#C9F4F4']
});
$('.container').highcharts({        
    chart: {
        type: 'area',          
    },
    credits: {
        enabled: false
    },
    title: {
        text: ''
    },
    xAxis: {
        categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'June', 'Jul','Aug','Sep','Oct','Nov','Dec'],
        tickmarkPlacement: 'on', 
        overflow:'false',
        gridLineWidth: 1,
        //tickLength: 0,
        startOnTick:true,
        title: {
            enabled: false
        }
    },
    yAxis: {             
        min: 100, 
        max: 1000,
        tickInterval: 100,                           
        gridLineWidth: 1,               
        title: {
            enabled: false
        },
        labels: {                                
            formatter: function () {
                return this.value;
            }
        }
    },
    tooltip: {
        shared: true, 
        formatter: function () {
            return this.y;
        }
    },
    plotOptions: {
        series: {                
            lineColor: '#00CFCF',
            lineWidth: 1,
            marker: {
                lineWidth: 1,
                lineColor: '#00CFCF',
                enabled: false,                    
            }
        }
    },
    navigation: {
        buttonOptions: {
            enabled: false
        }
    },
    series: [{
        name: 'Asia',
        data: [502, 635, 809, 947, 900, 1000, 1000,200,750,630,400,75]
    }]
});

});

这里是JSFiddle

是想要的效果吗? http://jsfiddle.net/xznu95mv/5/

x轴部分,
startOnTick: true, 更改为 startOnTick: false,
添加 min: 0.5
