r - 如何在 R 中的图例中隐藏痕迹

Question

我有一个带有几条痕迹的 plotly 图。其中一些我不想出现在传说中。我该怎么做呢？

Answer 1

您需要设置showlegend = F在你的踪迹中:

代码

library(plotly)
plt <- plot_ly(as.data.frame(mtcars)) %>% 
  add_markers(x = ~wt, y = ~mpg, name = 'Fuel Eff.', type = 'scatter') %>% 
  add_markers(x = ~wt, y = ~hp, name = 'Power to wt. ratio', type = 'scatter', 
              showlegend = F) %>%
  layout(
    showlegend = T, 
    legend = list(orientation = 'h')
  )

输出
