How to set plotly chart to have a transparent background in R?

问题

Here's what I have, so far:

f1 <- list(
   family = "Arial, sans-serif",
   size = 25,
   color = "white"
)
f2 <- list(
   family = "Old Standard TT, serif",
   size = 14,
   color = "black"

)
a <- list(
   title = "SALES PER SONG",
   titlefont = f1,
   showgrid = FALSE,
   showticklabels = TRUE,
   showline=TRUE,
   tickangle = 45,
   tickfont = f2
  )

 salesplot <-plot_ly(producersales, type="scatter", x=Producer, y=SalesPerSong, color=SongRange, colors=cols, mode="markers", size=SalesPerSong) %>% 
layout(xaxis = a, yaxis = a)

I tried adding paper_bgcolor=#00000000, plot_bgcolor=#00000000 after the x and y axis information within layout(), but when I run the command, I get the plus sign. I don't know what to do, so any help is appreciated. Thanks!

Just try:

salesplot <-plot_ly(producersales, type="scatter", x=Producer, y=SalesPerSong, color=SongRange, colors=cols, mode="markers", size=SalesPerSong) %>% 
layout(xaxis = a, yaxis = a) %>% 
layout(plot_bgcolor='rgb(254, 247, 234)') %>% 
layout(paper_bgcolor='rgb(254, 247, 234)') #will also accept paper_bgcolor='black' or paper_bgcolor='transparent'

You can change the rgb numbers to fit your needs.
