R程序可视化+如何在分类和数字数据之间绘图

时间：2017-03-20 04:58:14

标签： r ggplot2 numerical

我想开发一个可视化图形，其中x轴为日期，Y轴为A，B，C值。值分类数据和B，c是数值数据。在x轴上，日期应以月份和日期表示，如（01 / 07,02 / 07）。这里的问题是A值是分类数据，B值是数值数据。可视化图表不应该是条形图。它就像散点图。

我不知道怎么做这个。你的帮助会非常明显。感谢。

我试过这段代码。它适用于像B这样的一个值。当我尝试将C值与B一起绘制时，图形似乎不同。

 library(scales)
 library(ggplot2)
 ggplot(df, aes(x = Date, y = B)) +
 geom_line(aes(y=B,group=1),colour="#000099") +
 geom_point(size=2, colour="#CC0000") +   
 scale_y_continuous(breaks = seq(0, 50, by = 1)) + 
 scale_x_datetime(date_breaks = "2 day")

这是一种可行的方法。我不确定这是否理想，但希望对你的情况有所帮助：

使用标记

#library(devtools)
#install_github("ropensci/plotly")

library(plotly)
library(zoo)

df$Date <- as.yearmon(df$Date)
df$Date <- as.Date(df$Date)

plot_ly(df, x = ~Date) %>% 
    add_markers(y = ~B, marker = list(size = 15, symbol = "cross"), 
                name = "B") %>% 

    add_markers(y = ~C, marker = list(size = 10, symbol = "circle"),
                name = "C") %>% 

    add_markers(y = ~A, marker = list(size = 20, symbol = "diamond-open"),
                name = "A", yaxis = "y2") %>% 

    layout(xaxis = list(domain = c(0, 0.9)),
           yaxis2 = list(side = "right", anchor = "xaxis", overlaying = "y", title = "A"),
           yaxis = list(title = "B/C"))

使用行

#library(devtools)
#install.github("ropensci/plotly")

library(plotly)

df$x <- 1:nrow(df)
df$Date <- as.character(as.Date(df$Date))

plot_ly(df, x = ~x) %>% 

    add_lines(y = ~B, line = list(width = 5), opacity = "0.5",
              name = "B") %>% 

    add_lines(y = ~C, line = list(width = 5, dash = "5px"),
              name = "C") %>% 

    add_markers(y = ~A, marker = list(size = 15, symbol = "cross"),
                name = "A", yaxis = "y2") %>% 

    layout(xaxis = list(domain = c(0, 0.9), title = "",
                        tickmode = "array",
                        tickvals = ~x,
                        ticktext = ~Date,
                        tickfont = list(size = 10)),
           yaxis2 = list(side = "right", anchor = "xaxis", overlaying = "y", title = "A"),
           yaxis = list(title = "B/C"))
