我使用 amchart 4 创建了一个XYChart,更准确地说是一个堆积柱形图,我想让列标签可点击。这是我所做的(用一点树枝):

var chart = am4core.create("chartdiv", am4charts.XYChart);

chart.data = [
    {
        'CategoryAxis' : 'Column label 1',
        {% for valueAxis in listValueAxes %}
            '{{ valueAxis.name }}': {{ valueAxis.numericalValue }},
        {% endfor %}
    },{
        'CategoryAxis' : 'Column label 2',
        {% for valueAxis in listValueAxes %}
            '{{ valueAxis.name }}': {{ valueAxis.numericalValue }},
        {% endfor %}
    }
];

var categoryAxis = chart.xAxes.push(new am4charts.CategoryAxis());
categoryAxis.dataFields.category = "CategoryAxis";

var valueAxis = chart.yAxes.push(new am4charts.ValueAxis());
valueAxis.renderer.labels.template.disabled = true;

var label = categoryAxis.renderer.labels.template;

function createSeries(field) {
    var series = chart.series.push(new am4charts.ColumnSeries());
    series.dataFields.valueY = field;
    series.dataFields.categoryX = "CategoryAxis";
    series.stacked = true;

    return series;
}

{% for valueAxis in listValueAxes %}
    series = createSeries('{{ valueAxis.name }}');
    // Clickable cells
    series.columns.template.url = "{{path('viewValueAxis', {'id':valueAxis.id})}}";
{% endfor %}

url属性的最后一行允许单击列的“单元格”并重定向到专用于所表示值的页面。我想让列的标签也可以点击。我试图做这样的事情:

{% for categoryAxis in listCategoryAxes %}
    label.events.on("hit", function(){
        window.location.href = "{{path('viewCategoryAxis', {'id':categoryAxis.id})}}";
        }, this);
{% endfor %}

问题是标签没有被独立处理,它们重定向到同一页面。我想使用该url属性,但点击的目标是在标签上而不是列本身。我会使用类似的东西series.columns.template.labels.url或者可能是该urlTarget 属性,但这些似乎都不起作用。

如果您的数据中有 url,那么做您需要的最简单的方法是设置:

categoryAxis.renderer.labels.template.propertyFields.url = "url"

与命中事件相同:

categoryAxis.renderer.labels.template.events.on("hit", function(event){
     window.location.href = event.target.dataItem.dataContext.url;
})
