跟蹤順序圖R

Question

我試圖弄清楚如何控制以繪圖方式繪制的跡線的順序，即如何將跡線帶到正面和背面。

這里有一段簡單的代碼繪制了兩條軌跡。 如何確定訂單？

library(plotly)

airquality_sept <- airquality[which(airquality$Month == 9),]
airquality_sept$Date <- as.Date(paste(airquality_sept$Month, 
airquality_sept$Day, 1973, sep = "."), format = "%m.%d.%Y")

plot_ly(airquality_sept) %>%
add_trace(x = ~Date, y = ~Wind, type = 'bar', name = 'Wind',
        marker = list(color = '#C9EFF9')
       ) %>%  
add_trace(x = ~Date, y = ~Temp, type = 'scatter', mode = 'lines', name = 'Temperature', yaxis = 'y2',
        line = list(color = '#45171D')
) %>%

layout(title = 'New York Wind and Temperature Measurements for September 1973',
     xaxis = list(title = ""),
     yaxis = list(side = 'left', title = 'Wind in mph'),
     yaxis2 = list(side = 'right', overlaying = "y", title = 'Temperature in degrees F'))

Answer 1

scatter軌跡的y軸設置為y2並且layout yaxis2 overlaying y 。

如果要在背景中顯示scatter軌跡，請反轉y軸分配或在yaxis中將overlaying設置為y2 。

library(plotly)

airquality_sept <- airquality[which(airquality$Month == 9),]
airquality_sept$Date <- as.Date(paste(airquality_sept$Month, 
                                      airquality_sept$Day, 1973, sep = "."), format = "%m.%d.%Y")

plot_ly(airquality_sept) %>%
  add_trace(x = ~Date, y = ~Temp, type = 'scatter', mode = 'lines', name = 'Temperature', yaxis = 'y2',
            line = list(color = '#45171D')
  ) %>%
  add_trace(x = ~Date, y = ~Wind, type = 'bar', name = 'Wind',
            marker = list(color = '#C9EFF9', opacity = 0.5)
  ) %>%
  layout(title = 'New York Wind and Temperature Measurements for September 1973',
         xaxis = list(title = ""),
         yaxis = list(side = 'left', title = 'Wind in mph', overlaying = "y2"),
         yaxis2 = list(side = 'right', title = 'Temperature in degrees F'))
