在ggplotly中使用Aes

Question

我从aes中打印了一些东西，即"alpha“和"Continent"，我不知道为什么是这样的。请帮我删除它！

ggplot的部分代码：

server <- function(input, output) {    
  observe({
    output$plot1 <- renderPlotly({
      p <- ggplot(df1(), aes(x = df1()[,4], y = Happiness.Score))
      p <- p + geom_point(size = 2, aes(text = paste("Country:", df1()[,1]), color = Continent,  alpha = 0.85)) + 
        labs(title = "How happy is the country?", x = names(df1())[4], y = "Happiness Score") + 
        theme_light(base_size = 12) + ylim(2,8) 
      ggplotly(p, tooltip = c("text", "y"))
    })
  })

Continent是图例标题。要更改它，您可以执行以下操作：

...... + scale_color_discrete(name = "MY_LEGEND_TITLE")

要删除alpha，请将其设置在aes之外

geom_point(aes(text = paste("Country:", df1()[,1]), color = Continent), 
           size = 2, alpha = 0.85)
