在处理大型数组时，Highcharts Y-Axis跳过标签

Question

我的Y轴数组：

["1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24"]

图表不显示所有数字，仅显示1,3,5等。正在跳过2,4,6。如何强制Highcharts显示所有标签？

Answer 1

你想要的是将label.step设置为`：

    labels: {
        step: 1
    }

这会强制highcharts为每个类别/刻度呈现标签。

Answer 2

默认行为是如果它们彼此太靠近则删除刻度线。您可以使用tickPositioner强制所有刻度，而不是指定categories：

    yAxis: {
        title: null,
        tickPositioner: function () {
            return [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24];
        }
    },

请注意，引号已被删除，即返回的数组包含数字（而不是原始问题中的字符串文字）。不知道为什么它不能用于字符串文字。
