问题描述

我在ggplotly中如何定位主标题和图例时遇到问题.我希望我的主要标题在图表的顶部并保持对齐.我也希望我的图例位于图表的底部

I am having issues on how to position the main title and legend in ggplotly. I would like my main title to be on the top of the graph and left aligned. I would also like my legend to be at the bottom center of the graph

这是我的代码

library(dplyr)
library(tidyr)
library(plotly)

推荐答案

我没有找到标题问题的任何解决方案.看看这对您的传说是否有帮助.

I didn't find any solution for the title problem. See if this will help you regarding the legend.

p <- ggplot(combined_data, aes(Month_Names, y = Actual_volume,
                           group = TrendName,
                           color = TrendName)) +
  geom_line() +
  labs(x=" ",y=" ") +
  labs(title = "New plot title") +
  theme(plot.title = element_text(family = "Trebuchet MS", color="blue", 
                              size=18, 
                              margin = margin(10, 0, 10, 0)),
    legend.position = "bottom",
    legend.title = element_blank(),
    #axis.text.x = element_text(angle = 45, hjust = 1)
    axis.text.x = element_blank(),
    axis.ticks.x = element_blank()
  )

ggplotly(p) %>% 
  layout(title = "New plot title",
     #xaxis = list(showticklabels = FALSE),
     legend = list(orientation = "h",
                   y = 0, x = 0))
