Iは、xとyの値の両方を有する各チャートラインの上部に小さな白いボックスを追加します。私を助けてください。

あなたはこのようにそれを行うことができます。

まずあなたが両方のxを表示するよう（IDのX-テキストとテキストを作成し、以下に示すように、Y-textがグループに追加しy値は）。

mousePerLine.append("rect") 
    .attr("x", 0) 
    .attr("y", -10) 
    .attr("width", 70)//width of rectangle 
    .attr("height", 35)//height of rectangle 
    .style("stroke", function(d, i) { 
    return z(i); 
    }) 
    .attr("class", "tooltip-container")//add class for styling rectangle 
    .style("fill", "red")//give color red to it. 
    .style("opacity", "0") 
    .style("stroke-width", "1px");

作業コード：

//for y text on tooltip 
d3.select(this).select('#y-text') 
    .text("y: " + y.invert(pos.y).toFixed(2)); 
//make date in the format %H:%M:%S for x tooltip 
d3.select(this).select('#x-text') 
    .text("x: " + d3.time.format("%X")(xDate));

次はスタイリングのためのツールチップの周りに四角形を作る：

mousePerLine.append("text").attr("id", "x-text") 
    .attr("transform", "translate(10,3)"); 
mousePerLine.append("text").attr("id", "y-text") 
    .attr("transform", "translate(10,23)");

次は、このようなマウスを移動して、上記で作成したテキストに値を表示することができますhere

解決していただきありがとうございますが、もう1つ手助けできますか？私は、マウスが動いたときにラインを削除したいと思います。また、グラフが交差したり、近くに近づいたりするようなツールチップを配置したい場合は、ツールチップの長方形が交差して自動的に配置を変更するべきではありません。それは可能ですか？ – nikunj2512

@ nikunj2512ツールチップが交差するようになると、それは難しいコールです.. :( – Cyril
