# 상기 주소로 가서 Candlestick class 의 parameter 을 살펴보면 다양한 종류가 있습니다.

# 이전 살펴보기에서 어떤식으로 간략히 그릴수 있는지 살펴봤었고, x, close, high, open, low 값을 통해 그릴 수 있었습니다.

# 이외에도 다양하게 있는데 하나씩 살펴볼려고 합니다.

* 찾아봐도 모르겠는건 과감히~~^^ pass~~^^;;;;;;;;;;;; 누가 좀 알려주세용~^^

* close – Sets the close values.

# 종가 가격

* closesrc – Sets the source reference on Chart Studio Cloud for close .

# Chart Studio Cloud 에서 어떤 셋팅을 하는 것 같다. 주피터에서는 별다른 작동을 안함.

* customdata – Assigns extra data each datum. This may be useful when listening to hover, click and selection events. Note that, “scatter” traces also appends customdata items in the markers DOM elements

# unknown function ^^;;

* decreasing – plotly.graph_objects.candlestick.Decreasing instance or dict with compatible properties

* class plotly.graph_objects.candlestick.Decreasing(arg=None, fillcolor=None, line=None, **kwargs)

# 선 또한 rgb, hex 등등으로 색을 변경할 수 있습니다.
