如何在 amCharts 4 中绘制堆积条形图的轮廓?
How to outline a stacked bar chart in amCharts 4?
我目前在 amCharts 4 中使用 Stacked XYChart,并且我只显示一个柱:
我正在尝试弄清楚如何在 整个 栏周围绘制轮廓 - 如下所示:
我已经尝试将 stroke
(以及 strokeWidth
和 strokeOpacity
)属性 添加到几乎所有内容 - 系列、yAxes、xAxes 等,但其中 none 产生了我希望的结果。我觉得我缺少了一些明显的东西,所以非常感谢任何帮助。
我认为这是我们可以实现的。它不会根据您的要求提供连续行程。
你可能试过这个。
function createSeries(field, name) {
var series = chart.series.push(new am4charts.ColumnSeries());
series.dataFields.valueX = field;
series.dataFields.categoryY = "year";
series.stacked = true;
series.name = name;
series.stroke = am4core.color("#000");
var labelBullet = series.bullets.push(new am4charts.LabelBullet());
labelBullet.locationX = 0.5;
labelBullet.label.text = "{valueX}";
labelBullet.label.fill = am4core.color("#fff");
}
既然你提到你只显示一列并假设这是一个 100% 堆叠图表,你能做的最好的就是在图表的 plotContainer
:
上设置一个笔划
chart.plotContainer.stroke = "#000000"
请注意,您的系列列需要将高度设置为 100%,这样它才能在容器内完全展开 (series.columns.template.height = am4core.percent(100)
)。
下面的演示:
var chart = am4core.create("chartdiv", am4charts.XYChart);
chart.data = [{
"year": "2016",
"europe": 2.5,
"namerica": 2.5,
"asia": 2.1,
"lamerica": 0.3,
"meast": 0.2,
"africa": 0.1
}];
chart.legend = new am4charts.Legend();
chart.legend.position = "top";
chart.plotContainer.stroke = "#000000";
chart.plotContainer.strokeWidth = 5;
var categoryAxis = chart.yAxes.push(new am4charts.CategoryAxis());
categoryAxis.dataFields.category = "year";
categoryAxis.renderer.grid.template.opacity = 0;
categoryAxis.renderer.labels.template.disabled = true;
var valueAxis = chart.xAxes.push(new am4charts.ValueAxis());
valueAxis.min = 0;
valueAxis.max = 100;
valueAxis.strictMinMax = true;
valueAxis.renderer.grid.template.opacity = 0;
valueAxis.renderer.labels.template.disabled = true;
valueAxis.renderer.baseGrid.disabled = true;
valueAxis.calculateTotals = true;
function createSeries(field, name) {
var series = chart.series.push(new am4charts.ColumnSeries());
series.dataFields.valueX = field;
series.dataFields.categoryY = "year";
series.dataFields.valueXShow = "totalPercent";
series.stacked = true;
series.name = name;
series.columns.template.height = am4core.percent(100);
}
createSeries("europe", "Europe");
createSeries("namerica", "North America");
createSeries("asia", "Asia");
createSeries("lamerica", "Latin America");
createSeries("meast", "Middle East");
createSeries("africa", "Africa");
