Recreate this Python Plotly-animation in R

Plotly R, MATLAB, Julia, Net Plotly R

I really like the recent version of Plotly in R with the animation options.

However, I would like to recreate this Python animation of a time series in R. Does anyone know if it is possible?

Hey @filipwastberg,

there’ll be some R animation docs online in the near future. For now, an example of filled-area animation:

library(plotly)
library(quantmod)

getSymbols("AAPL",src='yahoo')

df <- data.frame(Date=index(AAPL),coredata(AAPL))
df <- tail(df, 30)
df$ID <- seq.int(nrow(df))

accumulate_by <- function(dat, var) {
  var <- lazyeval::f_eval(var, dat)
  lvls <- plotly:::getLevels(var)
  dats <- lapply(seq_along(lvls), function(x) {
    cbind(dat[var %in% lvls[seq(1, x)], ], frame = lvls[[x]])
  })
  dplyr::bind_rows(dats)
}

df <- df %>%
  accumulate_by(~ID)

p <- df %>%
  plot_ly(
    x = ~ID, 
    y = ~AAPL.Close, 
    frame = ~frame,
    type = 'scatter', 
    mode = 'lines', 
    fill = 'tozeroy', 
    fillcolor='rgba(114, 186, 59, 0.5)',
    line = list(color = 'rgb(114, 186, 59)'),
    text = ~paste("Day: ", ID, "<br>Close: $", AAPL.Close), 
    hoverinfo = 'text'
  ) %>%
  layout(
    title = "AAPL: Last 30 days",
    yaxis = list(
      title = "Close", 
      range = c(0,200), 
      zeroline = F,
      tickprefix = "$"
    ),
    xaxis = list(
      title = "Day", 
      range = c(0,30), 
      zeroline = F, 
      showgrid = F
    )
  ) %>% 
  animation_opts(
    frame = 100, 
    transition = 0, 
    redraw = FALSE
  ) %>%
  animation_slider(
    currentvalue = list(
      prefix = "Day "
    )
  )

Nice @bcd ! Guess I should have looked a little bit closer in the animation_ops() documentation.

This was really helpful, however, is there a way to work with dates and key frame animations?

If I use x = ~Date the plot does not work.

library(plotly)
library(quantmod)

getSymbols("AAPL",src='yahoo')

df <- data.frame(Date=index(AAPL),coredata(AAPL))
df <- tail(df, 30)
df$ID <- seq.int(nrow(df))

accumulate_by <- function(dat, var) {
  var <- lazyeval::f_eval(var, dat)
  lvls <- plotly:::getLevels(var)
  dats <- lapply(seq_along(lvls), function(x) {
    cbind(dat[var %in% lvls[seq(1, x)], ], frame = lvls[[x]])
  })
  dplyr::bind_rows(dats)
}

df <- df %>%
  accumulate_by(~ID)

p <- df %>%
  plot_ly(
    x = ~Date, 
    y = ~AAPL.Close, 
    frame = ~frame,
    type = 'scatter', 
    mode = 'lines', 
    fill = 'tozeroy', 
    fillcolor='rgba(114, 186, 59, 0.5)',
    line = list(color = 'rgb(114, 186, 59)'),
    text = ~paste("Day: ", ID, "<br>Close: $", AAPL.Close), 
    hoverinfo = 'text'
  ) %>%
  layout(
    title = "AAPL: Last 30 days",
    yaxis = list(
      title = "Close", 
      range = c(0,200), 
      zeroline = F,
      tickprefix = "$"
    ),
    xaxis = list(
      title = "Day", 
      range = c(0,30), 
      zeroline = F, 
      showgrid = F
    )
  ) %>% 
  animation_opts(
    frame = 100, 
    transition = 0, 
    redraw = FALSE
  ) %>%
  animation_slider(
    currentvalue = list(
      prefix = "Day "
    )
  )

@bcd is there any way to use frame on Date-variables?

If I use x = ~Date the plot does not work.
