Graph 如何更改图表4中值/类别的文本颜色？

我想更改类别的颜色和文本的值（参见嵌入的图片），我不确定这是否与我的css样式或amcharts api有关。然而，我确实设法用

label.fill=am4core.color（“白色”）更改了标签

以及守则：

    am4core.ready(function() {

    const units = 'km';
    
    // Themes begin
    am4core.useTheme(am4themes_animated);
    
    // Themes end

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

    // Add data
    chart['data'] = [{"country":"","volume":'','Name':''}];

    // Create axes

    var categoryAxis = chart.xAxes.push(new am4charts.CategoryAxis());
    categoryAxis.dataFields.category = "country"; 
    categoryAxis.renderer.grid.template.location = 10;
    categoryAxis.renderer.minGridDistance = 20;

    var valueAxis = chart.yAxes.push(new am4charts.ValueAxis());

    // Create series
    var series = chart.series.push(new am4charts.ColumnSeries());
    series.dataFields.valueY = "volume";
    series.dataFields.categoryX = "country";
    series.dataFields.countryNameX = "c_name";
    series.name = "volume";     
    
    series.columns.template.tooltipText = "{countryNameX}: [bold]{valueY}[/] "+units;
    series.columns.template.fillOpacity = .8;

    //label units on left side
    var label = chart.createChild(am4core.Label);
    label.text = units;
    label.fontSize = 16;
    label.align = "left";
    label.rotation=270;
    label.isMeasured = false;
    label.x = -10;
    label.y = 50;
    label.fill = am4core.color("white");
    
    var columnTemplate = series.columns.template;
    columnTemplate.strokeWidth = 1;
    columnTemplate.strokeOpacity = 1;       
    }); 

您需要直接在axis对象的标签模板上设置颜色，如下所述：

    am4core.ready(function() {

    const units = 'km';
    
    // Themes begin
    am4core.useTheme(am4themes_animated);
    
    // Themes end

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

    // Add data
    chart['data'] = [{"country":"","volume":'','Name':''}];

    // Create axes

    var categoryAxis = chart.xAxes.push(new am4charts.CategoryAxis());
    categoryAxis.dataFields.category = "country"; 
    categoryAxis.renderer.grid.template.location = 10;
    categoryAxis.renderer.minGridDistance = 20;

    var valueAxis = chart.yAxes.push(new am4charts.ValueAxis());

    // Create series
    var series = chart.series.push(new am4charts.ColumnSeries());
    series.dataFields.valueY = "volume";
    series.dataFields.categoryX = "country";
    series.dataFields.countryNameX = "c_name";
    series.name = "volume";     
    
    series.columns.template.tooltipText = "{countryNameX}: [bold]{valueY}[/] "+units;
    series.columns.template.fillOpacity = .8;

    //label units on left side
    var label = chart.createChild(am4core.Label);
    label.text = units;
    label.fontSize = 16;
    label.align = "left";
    label.rotation=270;
    label.isMeasured = false;
    label.x = -10;
    label.y = 50;
    label.fill = am4core.color("white");
    
    var columnTemplate = series.columns.template;
    columnTemplate.strokeWidth = 1;
    columnTemplate.strokeOpacity = 1;       
    }); 

categoryAxis.renderer.labels.template.fill = am4core.color("#ffffff");
valueAxis.renderer.labels.template.fill = am4core.color("#ffffff");
