制定3个月的天然气价格曲线。我有一些轴问题。我希望能够显示日期而不是天数。曲线图中的格式化轴图R
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")))

非常感谢你,任何想法如何在x轴上反转轴标签?最后一个对不起 – Rhodo
