删除yAxis和highcharts中的数据之间的空格

Question

我想删除y轴和图表之间的空格,如下所示:

这是用于创建此图表的小提琴:此图表的jsFiddle

以下是用于设置的代码(与jsFiddle相同):

$(function () {
   var chart;
        $(document).ready(function () {
            chart = new Highcharts.Chart({
                chart: {
                    renderTo: 'container',
                    spacingLeft: 2,
                    spacingRight: 2
                },
                credits: { enabled: false },
                title: { text: '' },
                yAxis: {
                    title: '',
                    labels: {
                        style: {
                            fontSize:'9px'
                        }
                    }
                },
                xAxis: { labels: { enabled: false } }, //hide the x axis labels 

                series: [{
                    type: 'area',
                    name: 'speed',
                    showInLegend: false,
                    data: [

                }],
                /* To make it pretty */
                plotOptions: {
                    area: {
                        animation: false,
                        lineWidth: 1,
                        marker: {
                            enabled: false,
                            states: {
                                hover: {

                                }
                            }

                        shadow: false,
                        states: {

                            }
                        },
                        threshold: null
                    }
                }
            });
        });

});

正确的方法是将offset设为-15。

yAxis: {
    offset: -15
}

抵消：

The distance in pixels from the plot area to the axis line. A positive offset moves the axis with it's line, labels and ticks away from the plot area. This is typically used when two or more axes are displayed on the same side of the plot. Defaults to 0.
