На оси X я показываю годы. Вот скрипка: fiddle
Моя проблема:

Так или иначе, чтобы я мог отображать годы как [1990''''2000'''' '2010''''2020]. Я имею в виду, что их должно быть 4 второстепенных тика за годы, которые не должны быть видны. Любая помощь приветствуется.Спасибо

Вы можете настроить renderer вашей оси label чтобы вернуть пустое значение для значений года, которые вы не хотите отображать:

{
    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 : '';
        }
    }
}
