Amcharts 多轴仅转换为 x,y

Question

我需要生成一个报告，按类别统计我系统上的问题线程，它使用 amcharts 4 和以下代码：

am4core.ready(function() {

// Themes begin
am4core.useTheme(am4themes_animated);
// Themes end

// Create chart instance
var chart = am4core.create("chart1", am4charts.XYChart);

//
chart.language.locale = am4lang_pt_BR;
chart.dateFormatter.language = new am4core.Language();
chart.dateFormatter.language.locale = am4lang_pt_BR;

// Increase contrast by taking evey second color
chart.colors.step = 2;

// Add data
chart.data = [{
    "date" : "2020-01",
    "Baixo" : 1596,
    "Médio" : 2902,
    "Alto" : 8702,
    "Critico" : 5695
},

我需要将左边的 4 个小节合并为一个小节。但是，我需要将它从 0 排序到我整个 json 中的最高值。我查看了 amcharts 文档并尝试堆叠条形图，但它弄乱了数字顺序。

有人可以帮助我吗？

Answer 1

如果不需要堆叠轴，为什么不对所有系列使用相同的轴？

am4core.ready(function() {

// Themes begin
am4core.useTheme(am4themes_animated);
// Themes end

// Create chart instance
var chart = am4core.create("chart1", am4charts.XYChart);

//
chart.language.locale = am4lang_pt_BR;
chart.dateFormatter.language = new am4core.Language();
chart.dateFormatter.language.locale = am4lang_pt_BR;

// Increase contrast by taking evey second color
chart.colors.step = 2;

// Add data
chart.data = [{
    "date" : "2020-01",
    "Baixo" : 1596,
    "Médio" : 2902,
