На оси Х Я отображаются years.Here является скрипку: fiddle
Myproblem:

Является ли их в любом случае, так что я мог показывать годы как [1990 '' '' '2000' '' '2010' '' '2020]. Я имею в виду, что они должны быть 4 минус-тиксами в течение многих лет, между которыми не должно быть видно. Любая помощь оценивается. Спасибо

Answer 1

Вы можете настроить renderer из вашего Акса label вернуть пустое значение для значений года вы не хотите показывать:

{ 
    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 : ''; 
     } 
    } 
}
