Adding an image to the center of a polar chart in plotly R

Plotly R, MATLAB, Julia, Net

I’d like to add an image to the center of a polar chart. This seems straightforward, however it seems the image is always added in a cartesian coordinate system which makes it difficult to align it correctly. More importantly, when zooming/resizing, the two coordinate systems seem to behave in a slightly different way and the position of the image becomes incorrect.

A very basic example of what does work as long as you don’t zoom or resize:

library(plotly)


fig <- plot_ly(
  type = 'scatterpolar',
  r = c(0,1,2,2),
  theta = c(0,45,90,0),
  mode = 'markers'
) 

fig |>  layout(
  images = list(
    list(
      source = "https://images.plot.ly/language-icons/api-home/r-logo.png?raw=true",
      xref = "x",
      yref = "y",
      x = 0.2,
      y = 3,
      sizex = 2,
      sizey = 2,
      sizing = "stretch",
      opacity = 1,
      layer = "above"
    )
  )
)

What I’d like to get to work is this: Posit Connect. This plot looks fine when viewed in full screen, however when zooming the image moves away from the center.

Is there a way to fix this?
