我一直在谷歌寻求帮助,但没有找到解决方案。你应该在节点上添加X和Y坐标:
var tempX = window.innerWidth/2;
var tempY = window.innerHeight/2;
var point = [tempX,tempY],
node = {imgsrc: "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-prn1/48799_806120304_700633127_n.jpg", x: tempX, y: tempY};
及
然后需要将变换添加到force.on(“tick”)函数中。…
函数:
vis.selectAll(".node")
.attr("transform", function(d) { return "translate(" + d.x + "," + d.y + ") scale(0.30)"; });
这会将图像比例降低到30%,但您可以对此进行配置

谢谢。我发现问题出在图像属性上,我只是更改了“cx”和“cy”的“x”和“y”值,并将其放在勾号函数:node.attr(“transform”,函数(d){return”translate(“+d.x+”,“+d.y+”);});
