r - 如何在 plot_geo() 函数中将 60M、40M 和 20M 的图例颜色更改为白色。它不可见，我想将颜色更改为白色

Question

我想从 plot_geo 中的图例文本中更改文本颜色。

p8=plot_geo(subscriber_by_countries, locationmode = "Country") %>% 
  add_markers(x = subscriber_by_countries$longitude,
              y = subscriber_by_countries$latitude,
              size = subscriber_by_countries$Subscribers,
              color = subscriber_by_countries$Subscribers,
              colors = rocket(50, alpha = 1, begin = 0, end = 1, direction = 1),
              hoverinfo = "text",
              hovertext = paste(" Country: ", subscriber_by_countries$Country, 
                               "\n","Subscribers: ", subscriber_by_countries$Subscribers)) %>% 
  layout(paper_bgcolor = '#141414', plot_bgcolor = '#141414')


p8
