私はしばらく私の頭を傷つけていましたが、誰かがd3 v4トランジションの仕組みを明確にするのに役立つことを願っています。d3トランジションバーグラフ

私は積み重なったバーグラフを持っており、バーの幅を広げようとしています。

You can see the current bargraph hereライン36は、長方形を描く場所です。

そして、何私がやろうとしてきたのでよう、各バーを移行です:

layer.selectAll("rect") 
    .data(function(d) { return d; }) 
    .enter().append("rect") 
    .attr("y", function(d) { return yScale(parseDate(d.data.date)); }) 
    .attr("x", function(d) { return xScale(d[0]); }) 
    .attr("height", yScale.bandwidth()) 
    .attr("width", function(d) { return xScale(d[1]) - xScale(d[0]) }) 
    .transition() //start transition here 
    .duration(500) 
    .delay(function(d,i) { return i * 100 }) 
    .attr("width", function(d) { return xScale(d[1]) - xScale(d[0]) }) 

私は、各矩形は500ミリ秒でその全幅に成長し、各矩形と共に成長遅延を持つことが期待されます。

D3 v4でトランジションを正しく実装するにはどうすればよいですか?

コードでは、ポイントAからポイントAに移行しようとしています。あなたは、これは私たちに

enter image description here

を、このような結果が得られます0

.attr("width", 0)

にする必要があり、あなたのバーは幅移行前 だから、0から点A

に移行する必要があります

あなたが見ることができる、そのバーは移行していますが、1つのグループではありません

ので、我々はまた、移行

.attr("x", 0)

x属性を変更し、移行後に前の行を移動することができます

.attr("x", function(d) { return xScale(d[0]); })

結果:
