在X轴上，我显示了年份。这是小提琴：
我的问题：

是他们的，所以我可以将年份显示为[1990”“2000”“2010”“2020]。我的意思是，他们应该是4个Minortick，在这两个年份之间，不应该是可见的。感谢任何帮助。谢谢

您可以配置axe的

渲染器

，为您不想显示的年份值返回空值：

{
    type: "Category",
    position: "bottom",
    minorTickSteps: 4,
    majorTickSteps: 5,
    maximum:50,
    minimum:0,
    fields: ["year"],
    title: "Year",

    label: {
        renderer: function(v) {
            return v % 10 === 0 ? v : '';
        }
    }
}
