javascript - D3 js selectAll each doesn't iterate -


i trying implement fisheye lens (cartesian) in scatterplot. trying follow this approach, apparently selector fails.

i have fisheye defined as

var fisheye = d3.fisheye.circular().radius(120);  svg.on("mousemove", function() {     fisheye.focus(d3.mouse(this));      console.log("here " + points.selectall("circle").length);      points.selectall("circle").each(function(d) {         console.log("aaa");         d.fisheye = fisheye(d);            /*points.selectall("circle")         .each(function(d) {              console.log("???");           this.attr("cx", function(d) {  return d.fisheye.x; })           this.attr("cy", function(d) { return d.fisheye.y; })           this.attr("r", function(d) { console.log("hype"); return 10; });         }); */     }); });

and points defined as

points = svg.append("g")     .attr("class", "point")     .selectall("circle")     .data(dataset)     .enter()     .append("circle")     .attr("cx", function(d) { // set x position using x-scale         return x(d.x);     })     .attr("cy", function(d) { // set y position using y-scale         return y(d.y);     })     .attr("r", 5) // set radius of every point 5     .on("mouseover", function(d) { // on mouse on show , set tooltip         if(!isbrushing){           tooltip.transition()                .duration(200)                .style("opacity", 0.9);            tooltip.html(d.symbol + "<br/> (" + parsefloat(x(d.x)).tofixed(4)             + ", " + parsefloat(y(d.y)).tofixed(4) + ")")                .style("left", (d3.event.pagex + 5) + "px")                .style("top", (d3.event.pagey - 28) + "px");         }       })       .on("mouseout", function(d) { // on mouseout, hide tooltip.           tooltip.transition()                .duration(500)                .style("opacity", 0);       });

the console.log "here" spamming when moving mouse, , shows correct amount. hwoever, each loop never executed not see "aaa". have tried use selectall("circle") doesn't work either.

what doing wrong , how can fisheye work?
