你能帮我在项目符号内的图片周围应用边框半径吗?

您可以调整项目符号内 circlebackground 对象中的 radius 属性,以用圆边遮盖图像并控制项目符号的大小。在您的情况下,将圆半径降低到 13 就足够了:

    var imageBullet1 = series.bullets.push(new am4plugins_bullets.PinBullet());
    // ...
    imageBullet1.circle.radius = 13;

Updated codepen

您可能会发现 bullet configuration tool from the bullet plugin tutorial 有助于理解某些属性如何影响项目符号的外观。
