我有2行高图图表。 x轴是日期时间类型。
我想在整个日期范围内每个月在x轴上标记一个标记：7月11日，8月11日，9月11日等等。
如果我将父容器设置为非常宽，则显示所有月份刻度的唯一方法。但是，我的生产布局只有一个695px的容器。
当我在较小的宽度时，如何强制显示所有刻度？
这是我的代码：
var chart;
var lineIndex = 0,splineIndex=0;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
zoomType: 'xy'
},

}

}
},

formatter: function() {

}
},

} else if (this.y > 5) {
return '<div class="tweak-0">$' + Highcharts.numberFormat(Math.round(this.y),0,".",",") + '</div>';
} else if (this.x == Date.UTC(2011, 11, 1)) { // grab values for special dates and assign tweak classes so we can adjust the label spacing
return '<div class="tweak-1">$' + Highcharts.numberFormat(this.y,3,".",",") + '</div>';
} else if (this.x == Date.UTC(2012, 1, 1)) {

} else if ( this.x == Date.UTC(2012, 0, 17) ) {
return '<div class="tweak-4">$' + Highcharts.numberFormat(this.y,3,".",",") + '</div>';
}
}}
}

答案 0 :(得分：5)
您可以将tickInterval添加到xAxis属性：
...
tickInterval: 30 * 24 * 3600 * 1000,
...
会出现一些重叠，所以也可能想要rotate标签：
请参阅此jsfiddle。
