Добавление линейного указателя на основе линейных данных и всплывающей подсказки указателя на линейчатой диаграмме d3 v3
Как добавить указатель и подсказку типа http://bl.ocks.org/d3noob/a22c42db65eb00d4e369 дальше .
Я добавляю / / указатель на строку/ / конец раздела кода .но указатель не генерируется должным образом .отображается только один указатель. верхний левый угол . как я могу исправить это любое предложение?
Что я уже пробовал:
