d3js - `defined`

Question

を使用しながら、パスは私はこのようなバックエンドからデータを取得しています完全な値を描画されていません。（。。データは0値を持っている私は、ドローラインからこれらの値を防止していますので）

var line = d3.svg.line() 
       // .interpolate("basis") 
       .defined(function(d) { return d.temperature }) 
       .x(function(d) { return x(d.date); }) 
       .y(function(d) { return y(d.temperature); }); 

しかし、私は適切に描かれたパスを取得していない午前：私はこのようなdefinedを使用しています描画不要な値を防ぐために

。ここで写真を参照してください。

が実際に緑のラインがトップに策定する必要があります。赤い線はここで正しいです。私のアプローチに何が間違っていますか？

次に線を描画する正しい方法は何ですか？

更新 私は、この行をコメント場合、グラフは正常に動作します：

// path 
       //  .attr("stroke-dasharray", totalLength + " " + totalLength) 
       //  .attr("stroke-dashoffset", totalLength) 
       //  .transition() 
       //  .duration(2000) 
       //  .ease("linear") 
       //  .attr("stroke-dashoffset", 0); 

Answer 1

更新あなたは全体の長さを計算する方法：

var totalLength = [path[0][0].getTotalLength()]; 

あなたは

var totalLength = d3.max(path[0], function(d1){return d1.getTotalLength()}); 

を行う必要があります

このように、最大​​lengあなたは私は私のコードを共有する準備ができていたい場合はstroke-dashoffset
