である私は、タイトルの問題のための任意の解決策を見つけることができませんでした。伝説に関してこれがあなたを助けるかどうか見てください。

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))
