Highcharts 固定布局柱形图
以下实例演示了固定布局柱形图。
我们在前面的章节已经了解了 Highcharts 基本配置语法。接下来让我们来看下其他的配置。在 series 下添加 pointPlacement 和 pointPadding 配置。
series.pointPadding
控制每列之间的距离值,当highcharts图表宽度固定的情况下,此值越大,柱子宽度越小,反之相反。默认此值为0.1
series.pointPlacement
在柱形图中,当 pointPlacement 设置为 "on" 时, X轴上的点没有间隔。如果 pointPlacement 设置为 "between", 列之间按刻度进行布局。
在 Highcharts 3.0.2 后的版本, pointPlacement 可以支持数字,0 为轴上的值, -0.5 为当前值与前面一个值的间隔, 0.5 为 当前值与下一个值的间隔。 不同与文字设置选项,数字设置不影响轴之间的间隔。
series: { name: 'Employees', color: 'rgba(165,170,217,1)', data: [150, 73, 20], pointPadding: 0.3, pointPlacement: -0.2 }
