使用Highcharts renderer.rect函数时如何删除边框半径

Question

如何删除render.rect方法的边界半径。我试图添加使用此方法的CSS方法，但未成功。

.css({
   borderRadius: 'none'
})

这是我的代码。

Highcharts.chart('container', {
 		chart: {
            type: 'column'
    },
    xAxis: {
        categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
    },

    yAxis: {
        max: 300
    },

    series: [{
        data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
    }]

}, function (chart) {
		let maxPoint = chart.series[0].data.reduce((a, b) => a.y > b.y ? a : b);
    for(var i = 0; i <= 10; i++){
    var point = chart.series[0].data[i];
        let text = chart.renderer.text(
            'Hien' + i,
            point.plotX + chart.plotLeft + 10,
            maxPoint.plotY + chart.plotTop - 10
        ).attr({
            zIndex: 5
        }).add();
        let box = text.getBBox();

    chart.renderer.rect(point.plotX + chart.plotLeft + 5, maxPoint.plotY + chart.plotTop - 25, box.width + 10, box.height + 10, 5)
        .attr({
            fill: '#FFFFEF',
            stroke: 'gray',
            'stroke-width': 1,
            zIndex: 4
        }).css({
        	borderRadius: 'none'
        })
        .add();
    }
    
});

.rect()的语法是：

rect（[x] [，y] [，width] [，height] [，r] [，strokeWidth]）

第五个参数是边界角半径，因此您只需将其设置为0。

chart.renderer.rect(
  point.plotX + chart.plotLeft + 5, 
  maxPoint.plotY + chart.plotTop - 25, 
  box.width + 10, 
  box.height + 10, 
  0
)...

Highcharts.chart('container', {
 		chart: {
            type: 'column'
    },
    xAxis: {
        categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
    },

    yAxis: {
        max: 300
    },

    series: [{
        data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
    }]

}, function (chart) {
		let maxPoint = chart.series[0].data.reduce((a, b) => a.y > b.y ? a : b);
    for(var i = 0; i <= 10; i++){
    var point = chart.series[0].data[i];
        let text = chart.renderer.text(
            'Hien' + i,
            point.plotX + chart.plotLeft + 10,
            maxPoint.plotY + chart.plotTop - 10
        ).attr({
            zIndex: 5
        }).add();
        let box = text.getBBox();

    chart.renderer.rect(point.plotX + chart.plotLeft + 5, maxPoint.plotY + chart.plotTop - 25, box.width + 10, box.height + 10, 0)
        .attr({
            fill: '#FFFFEF',
            stroke: 'gray',
            'stroke-width': 1,
            zIndex: 4
        })
        .add();
    }
    
});
