曲線圖中的格式化軸圖R

Question

制定3個月的天然氣價格曲線。我有一些軸問題。我希望能夠顯示日期而不是天數。

library(ggplot2) 
library(Quandl) 
library(magrittr) 
require(plotly) 

#Get first 3 month on the nat gas curve data from Quandl 
my_start_date <- "2013-01-05" 

gas1<-Quandl("CHRIS/CME_NG1", start_date = my_start_date, type = "xts") 
gas2<-Quandl("CHRIS/CME_NG2", start_date = my_start_date, type = "xts") 
gas3<-Quandl("CHRIS/CME_NG3", start_date = my_start_date, type = "xts") 

#isolate the last prices 
gas1a<-gas1[,"Last"] 
gas2a<-gas2[,"Last"] 
gas3a<-gas3[,"Last"] 

p <- merge(as.zoo(gas1a), as.zoo(gas2a), as.zoo(gas3a), all = FALSE) 

#3d graph 
plot_ly(z = p, type = "surface")%>% 
    layout(title = "3 month Nat Gas curve", 
     scene = list(
      xaxis = list(title = "Month"), 
      yaxis = list(title = "Days"), 
      zaxis = list(title = "Price")))

您是否正在尋找？

plot_ly(y=index(p), z = p, type = "surface")%>% 
    layout(title = "3 month Nat Gas curve", 
     scene = list(
      xaxis = list(title = "Month"), 
      yaxis = list(title = "Days", tickangle = 180), 
      zaxis = list(title = "Price")))
