工具提示不会更改d3.js

Question

我使用鼠标悬停功能在单独的div中显示点的详细信息，当我将鼠标悬停在另一个圆圈上时，它会首次出现，但是当我将鼠标悬停在另一个圆圈上时，它不会更改

d3.js代码

var points = g.selectAll("path")
                              .data(subset,function(d){return d.geometry.coordinates;});

                  points.enter().append("path");
                  points.attr("d", path).attr("class", "points");
                  points.attr("d",path.pointRadius(function(d) {  return sizeScale(d.properties[size_name]);}));
                  points.style("fill-opacity", 0.4);
                  points.style("fill", function(d){ return ordinalScale(d.properties[color_name]);});
                  points.on("mouseover",function(d){
                    var details = [];
                    for(var prop in d.properties){
                      details.push(prop + " : " + d.properties[prop] + "<br/>");
                    }
                    console.log(details)
                    d3.select("#info_box").selectAll("li").data(details).enter().append("li").html(function(d){return d;});

                   });
