R中ggplotly的透明背景不可能

Question

这是我的主题

theme(
text = element_text(size = 14, color = "white"),
axis.text = element_text(size = 10, color = "white", face = "bold"),
axis.text.y =element_blank(),
panel.grid.major = element_blank(),
panel.grid.minor = element_blank(),
plot.background = element_rect(fill = "transparent",colour = NA),
axis.line.x = element_blank(),
axis.title.x =       element_blank(),
axis.title.y =       element_blank(),
panel.background =   element_rect(fill = "transparent",colour = NA),
plot.margin =        unit(c(1, 1, 1, 1), "lines"),
legend.text =        element_text(size = 10, 
color = "white",
face = "bold",
margin = margin(l = 0.25, unit = "cm")
),
legend.title =       element_blank(),
legend.background =   element_rect(fill = "transparent",colour = NA)
)
ggplotly(plot)

一切都按预期进行，我可以使用所有颜色，但当我将背景设置为透明时，我会得到白色背景。ggplotly不接受透明背景吗？

如果用替换透明，它能工作吗

你导出你的绘图是为了检查透明度吗？
