Question

当我实现d3 venn.js代码时-

d3.venn.js

<head>

}

               .venntooltip {

        var chart = venn.VennDiagram()

        var div = d3.select("#venn_one").datum(sets).call(chart);
            div.selectAll("text").style("fill", "white");
            div.selectAll(".venn-circle path")
                    .style("fill-opacity", .8)
                    .style("stroke-width", 1)
                    .style("stroke-opacity", 1)

        var tooltip = d3.select("#venn_one").append("div")
            .attr("class", "venntooltip");


        div.selectAll("g")
            .on("mouseover", function(d, i) {
                // sort all the areas relative to the current item
                venn.sortAreas(div, d);

                // Display a tooltip with the current size
                tooltip.transition().duration(40).style("opacity", 1);
                tooltip.text(d.size + "% of Audience One saw " + d.label);

                // highlight the current path
                // highlight the current path
                var selection = d3.select(this).transition("tooltip").duration(400);
                selection.select("path")
                    .style("stroke-width", 3)
                    .style("fill-opacity", d.sets.length == 1 ? .8 : 0)
                    .style("stroke-opacity", 1);
            })

            .on("mousemove", function() {
                tooltip.style("left", (d3.event.pageX) + "px")
                       .style("top", (d3.event.pageY - 28) + "px");
            })

            .on("mouseout", function(d, i) {

            });

    </script>

</div> 

</body>

</html>

，我得到以下输出：

在这里，在我的图像中，我也得到了重叠文本。但是，我想在交叉点处隐藏标签文本。

我试图对代码库本身进行更改，即在venn.js中进行更改，如脚本链接的代码中所述。

venn.js

  var enterPath = enter.append("path"),
            enterText = 
            enter.append("text")
            .attr("class", "label")
            // .text(function (d) { return "label(d)"; } )
            .text(function (d) { return null; } )  //kindly note
            .attr("text-anchor", "middle")
            .attr("dy", ".35em")
            .attr("x", width/2)
            .attr("y", height/2);




var updateText = update.selectAll("text")
                .filter(function (d) { return d.sets in textCentres; })
                // .text(function (d) { return label(d); } )
                .text(function (d) { return null; } )
                .attr("x", function(d) { return Math.floor(textCentres[d.sets].x);})
                .attr("y", function(d) { return Math.floor(textCentres[d.sets].y);});

但是，没有用。如何在http://bl.ocks.org/bessiec/986e971203b4b8ddc56d3d165599f9d0

上整齐地隐藏交集中的名称

如何在交集中隐藏标签并仅在d3 venn.js的工具提示中显示标签
