AMチャートをクリックしてもグラフデータが表示されない

Question

棒グラフをクリックするとグラフデータが表示されます。

私は青い線をクリックすると、それは2016年5月、すなわち、それぞれの年と月を返しますよう。同様に黄色の線をクリックすると、年と月が返されます。私はコードの下で試してみましたが、青い線または黄色の線のいずれかが1年しかないときに動作します。しかし、私は複数の年のグラフの同じコードをしようとしている年を得ることができません。添付のチャートを通過し、それに応じて対応してください

{result":[{"month":"Jan","year":"2016","totbooking":"0","nights":"0","comp_month":"Jan","year1":"2017","totbooking1":964,"nights1":"2685"},{"month":"Feb","year":"2016","totbooking":"0","nights":"0","comp_month":"Feb","year1":"2017","totbooking1":"0","nights1":"0"},{"month":"Mar","year":"2016","totbooking":"0","nights":"0","comp_month":"Mar","year1":"2017","totbooking1":"0","nights1":"0"},{"month":"Apr","year":"2016","totbooking":73,"nights":"154","comp_month":"Apr","year1":"2017","totbooking1":"0","nights1":"0"},{"month":"May","year":"2016","totbooking":240,"nights":"530","comp_month":"May","year1":"2017","totbooking1":"0","nights1":"0"},{"month":"Jun","year":"2016","totbooking":232,"nights":"544","comp_month":"Jun","year1":"2017","totbooking1":"0","nights1":"0"},{"month":"Jul","year":"2016","totbooking":224,"nights":"506","comp_month":"Jul","year1":"2017","totbooking1":"0","nights1":"0"},{"month":"Aug","year":"2016","totbooking":419,"nights":"1069","comp_month":"Aug","year1":"2017","totbooking1":"0","nights1":"0"},{"month":"Sep","year":"2016","totbooking":708,"nights":"1737","comp_month":"Sep","year1":"2017","totbooking1":"0","nights1":"0"},{"month":"Oct","year":"2016","totbooking":721,"nights":"1875","comp_month":"Oct","year1":"2017","totbooking1":"0","nights1":"0"},{"month":"Nov","year":"2016","totbooking":723,"nights":"1739","comp_month":"Nov","year1":"2017","totbooking1":"0","nights1":"0"},{"month":"Dec","year":"2016","totbooking":723,"nights":"1682","comp_month":"Dec","year1":"2017","totbooking1":"0","nights1":"0"}]}

：私は同じのために以下のコードを試してみました。私のコメントで述べたように

はあなたに

ありがとう、clickGraphItem eventでdataContextプロパティは、元のdataProvider配列から配列要素が含まれています。年にアクセスする必要がある場合は、名前で参照するだけです。あなたのグラフは、あなたがアクセスする必要のある年プロパティを決定するために、グラフのIDまたは他の識別子を使用して、自分の年のための具体的な情報をプロットするので：

"event": "clickGraphItem", 
"method": function(event) { 
    if (event.graph.id == "AmGraph-1") { 
    alert(event.item.dataContext.month + ' ' + event.item.dataContext.year); 
    } 
    else { 
    alert(event.item.dataContext.month + ' ' + event.item.dataContext.year2); 
    } 
}
