Hello there !
I am a beginner in plotly (very nice package by the way, thank you very much for this great job) and I am completely stuck on a very simple problem.
I try to embed a logo in my graph as here (https://plot.ly/r/logos/). When I take the example of this web page everything works correctly.
However, when I change the source of my image from a local image, no background is printed. I think that I have not correctly set up the parameters of my image layout but I cannot figure out how !!
I tried to look on the similar topics (http://stackoverflow.com/questions/39590845/embed-image-in-plotly , http://stackoverflow.com/questions/39490549/adding-an-image-logo-in-plotly-pie-chart) but I still don’t find my answer.
Here is my code:
library(plotly) outfile <- tempfile(fileext = ".png") png(outfile) plot(rnorm(200), rnorm(200)) dev.off() plot_ly(x = c(1, 2, 3), y = c(1, 2, 3)) %>% layout( images = list( list( source = outfile, xref = "x", yref = "y", x = 1, y = 1, sizex = 2, sizey = 2, sizing = "stretch", opacity = 0.4, layer = "below" ) ) )
Does anyone have an idea why it is not working?
Thank you very much in advance !!
