Candlestick data example

[Alik-V]

Hi Victor,

I hope you have been well. Thank you for the recent update to the package! The candlestick functionality comes at a perfect timing of needing to integrate a waterfall chart in my shiny app. And since I am using apexcharter exclusively for my plots, it would be great for me to try to make it by adjusting the candlestick plot you recently added.

My question is the following: having never dealt with candlestick plots before, I understand that the data structure needs to be slightly different. Could you please give a basic example of how the data and the chart code supposed to look like?

Best, Alik

Hi Alik,

Everything's fine here, hope you too. Thanks for your kind words.

Here's an example for the candlestick chart :

library(apexcharter)
data("candles")
apex(
  candles,
  aes(x = datetime, open = open, close = close, low = low, high = high),
  type = "candlestick"
)

candles is a data.frame with five columns. If you use the full API you can use a structure like :

list(
  list(
    x = "2020-07-02",
    y = list(1, 2, 3, 4)
  ),
  list(
    x = "2020-07-03",
    y = list(1, 2, 3, 4)
  )
)

But maybe for something that look like waterfall you can do something like this : https://apexcharts.com/javascript-chart-demos/column-charts/range-column-chart/ ? It's not implemented yet with apex() but doable with the full API.

Have a nice day,

Victor
