I'm looking for a way to automatically create buttons for different time periods in my dataset. As example from here shows it can be done using the following code:
library(plotly)
library(quantmod)
# Download some data
getSymbols(Symbols = c("AAPL", "MSFT"), from = '2018-01-01', to = '2020-01-01')
ds <- data.frame(Date = index(AAPL), AAPL[,6], MSFT[,6])
fig <- plot_ly(ds, x = ~Date)
fig <- fig %>% add_lines(y = ~AAPL.Adjusted, name = "Apple")
fig <- fig %>% add_lines(y = ~MSFT.Adjusted, name = "Microsoft")
fig <- fig %>% layout(
title = "Stock Prices",
xaxis = list(
rangeselector = list(
buttons = list(
list(
count = 3,
label = "3 mo",
step = "month",
stepmode = "backward"),
list(
count = 6,
label = "6 mo",
step = "month",
stepmode = "backward"),
list(
count = 1,
label = "1 yr",
step = "year",
stepmode = "backward"),
list(
count = 1,
label = "YTD",
step = "year",
stepmode = "todate"),
list(step = "all"))),
rangeslider = list(type = "date")),
yaxis = list(title = "Price"))
fig
However, now I'd like to create a buttons to select the first year (2018) and second year (2019) separately. Both stepmode options seems to define ranges backwards from the last date only, so I'm not really sure how can I specify the range for 2018 year. Is it possible? If so, how can it be done?
