使用两条轨迹从绘图图表的悬停文本中隐藏特定变量

Question

我有下面的数据框，并创建了一个 plotly 带有内圆的绘图对象。我的问题是我想跳过灰色和绿色圆点中的 value。

i <- 1

f<-bt %>% filter(issue==unique(bt$issue)[1]) %>%
ggplot(aes(x=year2))+
  
  geom_point(aes(y=value,size=value),color="gray")+
  geom_point(aes(y=value,size=percent),color="darkolivegreen")+
  scale_x_continuous(n.breaks=14)+
  theme(legend.position = 'none',
        axis.title.y = element_blank(),
        axis.text.y = element_blank())+
  labs(x="")

p2<-ggplotly(f)

p2$x$data[[1]]$text <- str_replace_all(p2$x$data[[1]]$text, 
                                       "year2", "Year") %>% 
  str_replace_all(., fixed("percent"),
                  "Percentage of all signed PTAs covering NTIs")

p2$x$data[[2]]$text <- str_replace_all(p2$x$data[[2]]$text, 
                                       "year2", "Year") %>% 
  str_replace_all(., fixed("percent"),
                  "Percentage of all signed PTAs covering NTIs")

Answer 1

我删除了过滤器以便绘制点。如果你想要在所有点上使用相同的工具提示，你可以将 text 添加到 ggplot(aes())。如果您仍然想要 darkolivegreen 点中的 percent，则需要将 text 添加到图层中。

短短几年，文字在ggplot():

f <- bt %>% # filter(issue == unique(bt$issue)[1]) %>%
  ggplot(aes(x = year2, text = paste0("Year: ", year2))) +
  geom_point(aes(y = value, size = value), color = "gray") +
  geom_point(aes(y = value, size = percent), color = "darkolivegreen") +
  scale_x_continuous(n.breaks = 14) +
  theme(legend.position  =  'none',
        axis.title.y = element_blank(),
        axis.text.y = element_blank()) +
  labs(x = "")

ggplotly(f, tooltip = "text")

如果您想要来自 percent 的值在适当的点上，请使用此选项。顺便说一句，我已将 percent 数据格式化为百分比。我提供了两种不同的方法来做到这一点。其中一种方法被注释掉了。没有被注释掉的使用scale包。两者都有效；当然，这取决于你。

f <- bt %>% # filter(issue == unique(bt$issue)[1]) %>%
  ggplot(aes(x = year2)) +
  geom_point(aes(y = value, size = value, text = paste0("Year: ", year2)),
             color = "gray") +
  geom_point(aes(y = value, size = percent,
                 # text = paste0("Year: ", year2, "\nPercent: ", round(percent, 3) * 100, "%")), 
                 text = paste0("Year: ", year2, "\nPercent: ", scales::percent(percent))), 
             color = "darkolivegreen") +
  scale_x_continuous(n.breaks = 14) +
  theme(legend.position  =  'none',
        axis.title.y = element_blank(),
        axis.text.y = element_blank()) +
  labs(x = "")

ggplotly(f, tooltip = "text")
