我的amCharts项目中至少有两个图像项目符号，并且我想对其中一个名为“ bullet” 的图像进行四舍五入。这是“项目符号” 存在的行...
var bullet = series.bullets.push(new am4charts.Bullet());
我找到了有关舍入自定义图像here的教程。它们在amCharts中用作项目符号，但它会将每个项目符号图像四舍五入，而我希望它仅舍入“ bullet” 而忽略“ bullet2”
这是我的代码（需要全尺寸）：
// Themes begin
am4core.useTheme(am4themes_animated);
// Themes end
// Create chart instance
var chart = am4core.create("chartdiv", am4charts.XYChart);
var myVar = {
Red: "#f72c69",
Normal: "#6887cc",
};
var userA_points = 22;
var userB_points = 20;
var userC_points = 6;
var members_points = 12;
var max_points = Math.max(userA_points, userB_points, userC_points, members_points);
var maxPlus = (max_points + 10);
maxPlus = Math.min(200, Math.max(0, maxPlus));
//console.log(maxPlus);
if (userA_points < members_points) {
var colorCompare = myVar.Red
} else {
var colorCompare = myVar.Normal
}
// Add data
chart.data = [{
"name": "Damon",
"points": userA_points,
"color": "#5479f2",
"bullet": "https://www.scripturaengage.com/wp-content/uploads/2017/05/Profile-Picture-Koen-VanGeert-circle-ScripturaEngage.png",

// Create axes

valueAxis.strictMinMax = true;
valueAxis.renderer.minGridDistance = 25;
// Do not crop bullets
chart.maskBullets = false;
// Remove padding
chart.paddingBottom = 0;
chart.paddingTop = 50;
// Create series

实际上，第一个项目符号模板不是四舍五入的东西。您使用的图像是透明的PNG。如果您在项目符号上设置了背景（例如黑色），则会看到该颜色出现在图像下方。
bullet.height = 120;
bullet.width = 120;
bullet.background.fill = am4core.color("black");
bullet.contentValign = "top";
bullet.verticalCenter = "top";
bullet.horizontalCenter = "middle";
bullet.contentAlign = "center"
对于第二组项目符号（bullet2），数据中的任何图像都不是我们可以测试/看到的东西，因此无法知道发生了什么。
这是一个快速演示：

现在，如果您想在图像周围添加自己的剪贴蒙版，则感谢xorspark，我已经找到了解决方法。创建一个Circle作为第一组子弹的子代，然后在Image上为其mask属性添加一个适配器，在其中返回子弹的圆圈。您必须使用与路线相关的属性才能正确定位。
例如
var mask = new am4core.Circle();
mask.radius = 40;
mask.horizontalCenter = "middle";
mask.verticalCenter = "middle";
mask.align = "center";
mask.valign = "top";
mask.parent = bullet;
image.adapter.add("mask", function(mask, target) {
return target.parent.children.getIndex(1)
});
演示（您将看到比平时更少的图像显示）：
