javascript - 如何放大 amCharts 系列的第一个项目符号？

标签 javascript amcharts amcharts4

这是我要修改的图表:

enter image description here

正如您所看到的，它是一个折线图，并且图像覆盖在每个系列的第一个项目符号上(用户图像!)。

现在我想要在每个图像周围有一个圆圈，其颜色与每个系列的线条相同。

类似这样的事情:

enter image description here 我认为，如果我们能够扩大每个系列的第一个项目的规模，我们就能实现这一目标。

这里是代码创建项目符号及其属性的位置，但此处的更改将影响 userA_series 中的所有项目符号:

var bullet = userA_series.bullets.push(new am4charts.CircleBullet())
bullet.circle.radius = 8;
bullet.fill = am4core.color("#ff0037");
bullet.stroke = am4core.color("#ff0037");
bullet.strokeWidth = 20;

这是完整的代码:

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

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

// Import data from server

var inGroup = true;


var repeats = ["Start", "Day", "Week", "Month", "3th Month", "Year", "7th", "8th", "9th", "10th"];

var userA_Diamonds = ["7", "12", "18", "24", "20", "16", "19", "25", "29", "32"];
var userA_Performance = ["94", "29", "40", "65", "88", "89", "90", "75", "80", "89"];
var userA_GameOvers = ["8", "4", "4", "3", "5", "2", "1", "0", "0", "1"];
var userA_Rank = ["115", "114", "100", "98", "87", "55", "12", "45", "65", "18"];

userA_Performance.length = 3;

var userB_Performance = ["62", "55", "78", "84", "89", "87", "95", "74", "112", "115", "114"];
userB_Performance.length = 2;

var userC_Performance = ["25", "36", "42", "51", "49", "61", "68", "75", "90", "100", "112"];
userC_Performance.length = 1;

var userD_Performance = ["45", "49", "68", "64", "89", "110", "87", "46", "89", "64", "89"];
userD_Performance.length = 1;

最佳答案

您可以使用Adapter为了那个原因。只需将适配器添加到子弹圆的 radius 属性即可:

bullet.circle.radius = 8;
bullet.circle.adapter.add("radius", (radius, target, key) => {
  if (target.dataItem.dataContext.repeat === 'Start') {
    return 50;
  }
  return radius;
});

在某些情况下，您应该更改 image.dy 属性以使图像在圆项目符号中居中:

image.dy = 50;

我创建了this code pen作为引用。但我只为第一个系列添加了适配器，其他的你必须自己做
