有时客户想要两个y标度。给他们“有缺陷的”言论通常是毫无意义的。但是我确实喜欢ggplot2坚持以正确的方式做事。我确信ggplot实际上是在向普通用户教育正确的可视化技术。您可以使用构面和自由缩放比较这两个数据系列吗? -例如看这里:https://github.com/hadley/ggplot2/wiki/Align-two-plots-on-a-page
评论
我同意安德烈亚斯(Andreas)的观点-有时(例如现在,对我而言),客户希望在同一图上获得两组数据,并且不想听我谈论图论。我要么说服他们不再想要(我并不总是想打一场仗),要么告诉他们“我使用的绘图程序不支持这一点。”因此,今天我将不再为此特定项目使用ggplot。 =(

无法同意此评论(请求)。尽可能多地压缩信息是很常见的(!)考虑到科学期刊等施加的严格限制,以便快速传达信息。因此,无论如何都要添加第二个y轴,我认为ggplot应该可以帮助实现这一点。

令人惊讶的是,像“有瑕疵的”和“正确的方式”这样的词语毫无疑问地被扔掉了,好像它们并不是基于一种理论,该理论本身实际上是固执己见的,教条主义的,但却被太多的人毫无疑问地接受了,正如在撰写本文时,这个完全无用的答案(抛出链接)的事实有72个投票。例如,比较时间序列时,将两个时间序列放在同一张图表上可能是无价的,因为差异的相关性更容易发现。只需询问成千上万每天都做这件事的受过高等教育的金融专业人士。

在ggplot2中是不可能的,因为我认为具有单独的y比例(而不是彼此转换的y比例)的图从根本上是有缺陷的。一些问题:它们是不可逆的:给定绘图空间上的一个点,您无法将其唯一地映射回数据空间中的一个点。
它们相对与其他选项相比,很难正确阅读。有关详细信息,请参见Petra Isenberg,Anastasia Bezerianos,Pierre Dragicevic和Jean-Daniel Fekete的“双尺度数据图表研究”。
它们很容易被误导:没有独特的方法来指定相对尺度。轴,使其易于操作。垃圾图表博客中的两个示例:一个,两个
它们是任意的:为什么只有2个标度,而不是3、4或10个?
您可能还想阅读Stephen Few冗长的讨论图中的双刻度轴主题是否是最好的解决方案?。

sec.axis = sec_axis(~ . * 1.20, name = "mpg (UK)")

采取上述答案并进行一些微调(无论其价值如何),这是一种通过sec_axis
实现两个量表的方法:假设一个简单(且完全是虚构的)数据集dt
:持续5天,它跟踪中断次数与生产率的关系: when numinter prod
1 2018-03-20 1 0.95
2 2018-03-21 5 0.50
3 2018-03-23 4 0.70
4 2018-03-24 3 0.75
5 2018-03-25 4 0.60
(两列的范围相差约5倍)。
以下代码将绘制两个序列,它们用完整个y轴:
ggplot() +
geom_bar(mapping = aes(x = dt$when, y = dt$numinter), stat = "identity", fill = "grey") +
geom_line(mapping = aes(x = dt$when, y = dt$prod*5), size = 2, color = "blue") +
scale_x_date(name = "Day", labels = NULL) +
scale_y_continuous(name = "Interruptions/day",
sec.axis = sec_axis(~./5, name = "Productivity % of best",
labels = function(b) { paste0(round(b * 100, 0), "%")})) +
theme(
axis.title.y = element_text(color = "grey"),
axis.title.y.right = element_text(color = "blue"))
结果是(上面的代码+一些颜色)调整):
要点(除了在指定y_scale时使用
sec_axis
外,还要在将第二个数据序列的每个值乘以5时指定序列)。在sec_axis定义中得到正确的标签,然后需要除以5(并格式化),因此上述代码中的关键部分实际上是geom_line中的*5
和sec_axis中的~./5
(将当前值.
除以5的公式)。 br /> 相比之下(我不想在这里判断方法),这就是两个图表彼此重叠的样子:
您可以自己判断哪种信息可以更好地传达信息(“不要打扰工作中的人!”)。猜测这是一种公平的决定方式。

有常见的双Y轴用例,例如显示每月温度和降水量的气候图。这是一个简单的解决方案,从威震天的解决方案中推广而来,它允许您将变量的下限设置为零以外的值:示例数据:
climate <- tibble(
Month = 1:12,
Temp = c(-4,-4,0,5,11,15,16,15,11,6,1,-3),
Precip = c(49,36,47,41,53,65,81,89,90,84,73,55)
)
将以下两个值设置为值接近数据的限制(您可以使用它们来调整图形的位置;轴仍然是正确的):
ylim.prim <- c(0, 180) # in this example, precipitation
ylim.sec <- c(-4, 18) # in this example, temperature
以下基于这些限制进行必要的计算,并制作图本身:
b <- diff(ylim.prim)/diff(ylim.sec)
a <- b*(ylim.prim[1] - ylim.sec[1])
ggplot(climate, aes(Month, Precip)) +
geom_col() +
geom_line(aes(y = a + Temp*b), color = "red") +
scale_y_continuous("Precipitation", sec.axis = sec_axis(~ (. - a)/b, name = "Temperature")) +
scale_x_continuous("Month", breaks = 1:12) +
ggtitle("Climatogram for Oslo (1961-1990)")
如果要确保红线与右y轴相对应,可以在代码中添加
theme
语句:ggplot(climate, aes(Month, Precip)) +
geom_col() +
geom_line(aes(y = a + Temp*b), color = "red") +
scale_y_continuous("Precipitation", sec.axis = sec_axis(~ (. - a)/b, name = "Temperature")) +
scale_x_continuous("Month", breaks = 1:12) +
theme(axis.line.y.right = element_line(color = "red"),
axis.ticks.y.right = element_line(color = "red"),
axis.text.y.right = element_text(color = "red"),
axis.title.y.right = element_text(color = "red")
) +

当我选择特定的轴限制时(在我的情况下为ylim.prim <-c(90,130)和ylim.sec <-c(15,30)),它并不适用,而是选择任意限制,将所有比例尺弄乱了。我不确定在复制上面的代码并更改变量名称和轴限制时缺少的内容
– Anke

@anke:当引用ylim.prim和ylim.sec时,文本有些草率。它们不是指轴的限制,而是指数据的限制。如前所述,当您设置ylim.prim <-c(90,130)和ylim.sec <-c(15,30)时,温度图最终在条形图上方结束(因为温度轴从-75开始) ,但每个图形的轴仍然正确。

您可以创建一个缩放系数,该缩放系数将应用于第二个几何图形和右y轴。这是从塞巴斯蒂安的解决方案派生的。library(ggplot2)
scaleFactor <- max(mtcars$cyl) / max(mtcars$hp)
ggplot(mtcars, aes(x=disp)) +
geom_smooth(aes(y=cyl), method="loess", col="blue") +
geom_smooth(aes(y=hp * scaleFactor), method="loess", col="red") +
scale_y_continuous(name="cyl", sec.axis=sec_axis(~./scaleFactor, name="hp")) +
theme(
axis.title.y.left=element_text(color="blue"),
axis.text.y.left=element_text(color="blue"),

大约3年前,Koske [KOHSKE]提供了解决此难题的技术骨干。在Stackoverflow上的多个实例中已讨论了该主题及其解决方案的技术问题[ID:18989001、29235405、21026598]。因此,我将使用上述解决方案仅提供特定的变体和一些解释性的演练。让我们假设我们在G1组中确实有一些数据y1与G2组中的某些数据y2以某种方式相关,例如范围/比例变换或添加了一些噪声。因此,人们希望将数据一起绘制在一个图上,其标度的左侧为y1,右侧为y2。
df <- data.frame(item=LETTERS[1:n], y1=c(-0.8684, 4.2242, -0.3181, 0.5797, -0.4875), y2=c(-5.719, 205.184, 4.781, 41.952, 9.911 )) # made up!
> df
item y1 y2
1 A -0.8684 -19.154567
2 B 4.2242 219.092499
3 C -0.3181 18.849686
4 D 0.5797 46.945161
5 E -0.4875 -4.721973
如果现在将数据与诸如
ggplot(data=df, aes(label=item)) +
theme_bw() +
geom_segment(aes(x='G1', xend='G2', y=y1, yend=y2), color='grey')+
geom_text(aes(x='G1', y=y1), color='blue') +
geom_text(aes(x='G2', y=y2), color='red') +
theme(legend.position='none', panel.grid=element_blank())
一起绘制在一起,则它与较小的y1会明显地被较大的y2破坏。
应对挑战的技巧是在技术上将两个数据集与第一个比例尺y1作图,但在第二个轴上报告第二个数据集,并用标签显示原始比例尺y2。
因此,我们构建了第一个辅助函数CalcFudgeAxis,该函数计算并收集要显示的新轴的特征。可以将该函数修改为超喜欢的(此函数仅将y2映射到y1的范围内)。
CalcFudgeAxis = function( y1, y2=y1) {
Cast2To1 = function(x) ((ylim1[2]-ylim1[1])/(ylim2[2]-ylim2[1])*x) # x gets mapped to range of ylim2
ylim1 <- c(min(y1),max(y1))
ylim2 <- c(min(y2),max(y2))
yf <- Cast2To1(y2)
labelsyf <- pretty(y2)
return(list(
yf=yf,
labels=labelsyf,
breaks=Cast2To1(labelsyf)
))
}
产生了一些东西:
> FudgeAxis <- CalcFudgeAxis( df$y1, df$y2 )
> FudgeAxis
$yf
[1] -0.4094344 4.6831656 0.4029175 1.0034664 -0.1009335
$labels
[1] -50 0 50 100 150 200 250
$breaks
[1] -1.068764 0.000000 1.068764 2.137529 3.206293 4.275058 5.343822
> cbind(df, FudgeAxis$yf)
item y1 y2 FudgeAxis$yf
1 A -0.8684 -19.154567 -0.4094344
2 B 4.2242 219.092499 4.6831656
3 C -0.3181 18.849686 0.4029175
4 D 0.5797 46.945161 1.0034664
5 E -0.4875 -4.721973 -0.1009335
现在,我将Kohske的解决方案包装在第二个辅助函数PlotWithFudgeAxis中(将新轴的ggplot对象和辅助对象放入该函数):
library(gtable)
library(grid)
PlotWithFudgeAxis = function( plot1, FudgeAxis) {
# based on: https://rpubs.com/kohske/dual_axis_in_ggplot2
plot2 <- plot1 + with(FudgeAxis, scale_y_continuous( breaks=breaks, labels=labels))
#extract gtable
g1<-ggplot_gtable(ggplot_build(plot1))
g2<-ggplot_gtable(ggplot_build(plot2))
#overlap the panel of the 2nd plot on that of the 1st plot
pp<-c(subset(g1$layout, name=="panel", se=t:r))
g<-gtable_add_grob(g1, g2$grobs[[which(g2$layout$name=="panel")]], pp$t, pp$l, pp$b,pp$l)
ia <- which(g2$layout$name == "axis-l")
ga <- g2$grobs[[ia]]
ax <- ga$children[[2]]
ax$widths <- rev(ax$widths)
ax$grobs <- rev(ax$grobs)
ax$grobs[[1]]$x <- ax$grobs[[1]]$x - unit(1, "npc") + unit(0.15, "cm")
g <- gtable_add_cols(g, g2$widths[g2$layout[ia, ]$l], length(g$widths) - 1)
g <- gtable_add_grob(g, ax, pp$t, length(g$widths) - 1, pp$b)
grid.draw(g)
}
现在可以将所有内容放在一起:下面的代码显示了如何在日常环境中使用建议的解决方案。现在,plot调用不再绘制原始数据y2,而是绘制一个克隆版本yf(保存在预先计算的帮助对象FudgeAxis中),该版本的缩放比例为y1。然后用Kohske的辅助函数PlotWithFudgeAxis处理原始的ggplot对象,以添加第二个轴来保留y2的比例。
FudgeAxis <- CalcFudgeAxis( df$y1, df$y2 )
tmpPlot <- ggplot(data=df, aes(label=item)) +
theme_bw() +
geom_segment(aes(x='G1', xend='G2', y=y1, yend=FudgeAxis$yf), color='grey')+
geom_text(aes(x='G1', y=y1), color='blue') +
geom_text(aes(x='G2', y=FudgeAxis$yf), color='red') +
theme(legend.position='none', panel.grid=element_blank())
PlotWithFudgeAxis(tmpPlot, FudgeAxis)
现在可以根据需要绘制两个轴,y1在左侧,y2在右侧
直截了当的解决方案是有限的摇摇欲坠。当它与ggplot内核一起使用时,将发出一些警告,通知我们交换事后的标度等。必须谨慎处理它,并且在其他情况下可能会产生某些不良行为。同样,可能需要四处寻找帮助功能以获取所需的布局。图例的位置就是一个问题(它将放置在面板和新轴之间;这就是我删除它的原因)。 2轴的缩放/对齐也有些挑战:当两个比例都包含“ 0”时,上面的代码可以很好地工作,否则一个轴会移动。因此,肯定会有一些改进的机会...
如果要保存图片,则必须将呼叫包装到设备打开/关闭中:

第一个
stat_summary
调用是设置基础的调用对于第一个y轴。第二个
stat_summary
调用被调用以转换数据。请记住,所有数据都将第一个y轴作为基础。因此,需要针对第一个y轴对数据进行标准化。为此,我对数据使用了转换函数:y=packetOkSinr*40 - 110
现在要转换第二个轴,我在
scale_y_continuous
调用中使用相反的函数:sec.axis=sec_axis(~.*0.025+2.75, name="y_second")

R可以做这样的事情coef(lm(c(-70,-110)〜c(1,0)))和coef(lm(c(1,0(7)-c(-70,-110))) )。您可以定义一个辅助函数,例如方程式<-function(range = c(-70,-110),target = c(1,0)){c = coef(lm(target〜range))as.formula(substitute (〜a *。+ b,list(a = c [[2]],b = c [[1]])))}

我们绝对可以使用基本R函数plot
构建具有双Y轴的图。 # pseudo dataset
df <- data.frame(x = seq(1, 1000, 1), y1 = sample.int(100, 1000, replace=T), y2 = sample(50, 1000, replace = T))
# plot first plot
with(df, plot(y1 ~ x, col = "red"))
# set new plot
par(new = T)
# plot second plot, but without axis
with(df, plot(y2 ~ x, type = "l", xaxt = "n", yaxt = "n", xlab = "", ylab = ""))
# define y-axis and put y-labs
axis(4)
with(df, mtext("y2", side = 4))

您可以在变量上使用facet_wrap(~ variable, ncol= )
来创建新的比较。它不在同一根轴上,但是相似。#12 楼
我承认并同意hadley(和其他公司)的观点,即单独的y尺度存在“根本缺陷”。话虽这么说–我经常希望ggplot2
具有此功能–特别是当数据为宽格式时,我很快想可视化或检查数据(即仅供个人使用)。tidyverse
库使将数据转换为长格式变得相当容易(这样facet_grid()
就可以使用),该过程仍然不容易,如下所示:library(tidyverse)
df.wide %>%
# Select only the columns you need for the plot.
select(date, column1, column2, column3) %>%
# Create an id column – needed in the `gather()` function.
mutate(id = n()) %>%
# The `gather()` function converts to long-format.
# In which the `type` column will contain three factors (column1, column2, column3),
# and the `value` column will contain the respective values.
# All the while we retain the `id` and `date` columns.
gather(type, value, -id, -date) %>%
# Create the plot according to your specifications
ggplot(aes(x = date, y = value)) +
geom_line() +
# Create a panel for each `type` (ie. column1, column2, column3).
# If the types have different scales, you can use the `scales="free"` option.
facet_grid(type~., scales = "free")

在撰写本文时,ggplot2已通过sec_axis支持此功能。

看来这似乎是一个简单的问题,但它围绕两个基本问题感到困惑。 A)如何在比较图中显示时如何处理多标量数据,其次,B)是否可以在不使用R编程的一些经验法则的情况下完成此操作,例如i)合并数据,ii)分面,iii)添加下面给出的解决方案满足上述条件,因为它无需重新缩放即可处理数据,其次,不使用提到的技术。
这里是结果,

Hadley的答案对Stephen Few的报告“图形中的双刻度轴是否是最好的解决方案?”提供了有趣的参考。我不知道OP对“计数”和“费率”的含义是什么。但是通过快速搜索可以得到计数和费率,因此我得到了一些有关北美登山运动中的事故的数据:在上述报告的第7页上(并按照OP的要求以条形图和线形图的形式显示计数):
另一个不太明显的解决方案是仅适用于时间序列,通过
显示每个值与参考值(或索引)值之间的百分比差异,从而将所有值集转换为通用的定量标度。例如,选择一个特定的时间点
(例如出现在图表中的第一个间隔),然后将每个后续值表示为它与
初始值之间的百分比差。这是通过将
时间的每个点的值除以初始时间点的值,然后将其乘以
100以将比率转换为百分比来完成的,如下所示。 >
Years<-c("1998","1999","2000","2001","2002","2003","2004")
Persons.Involved<-c(281,248,301,276,295,231,311)
Fatalities<-c(20,17,24,16,34,18,35)
rate=100*Fatalities/Persons.Involved
df<-data.frame(Years=Years,Persons.Involved=Persons.Involved,Fatalities=Fatalities,rate=rate)
print(df,row.names = FALSE)
Years Persons.Involved Fatalities rate
1998 281 20 7.117438

2003 231 18 7.792208
2004 311 35 11.254019
结果是这样的:

我发现这个答案对我的帮助最大,但是发现有些边缘情况似乎无法正确处理,特别是否定情况,还有我的极限距离为0的情况(如果我们抢劫的话可能会发生)我们根据数据的最大/最小限制)。测试似乎表明此方法始终有效。我使用以下代码。在这里,我假设我们想将[x1,x2]转换为[y1,y2]。我处理此问题的方法是将[x1,x2]转换为[0,1](足够简单的转换),然后将[0,1]转换为[y1,y2]。
climate <- tibble(
Month = 1:12,
Temp = c(-4,-4,0,5,11,15,16,15,11,6,1,-3),
Precip = c(49,36,47,41,53,65,81,89,90,84,73,55)
)
#Set the limits of each axis manually:
ylim.prim <- c(0, 180) # in this example, precipitation
ylim.sec <- c(-4, 18) # in this example, temperature
b <- diff(ylim.sec)/diff(ylim.prim)
#If all values are the same this messes up the transformation, so we need to modify it here
if(b==0){
ylim.sec <- c(ylim.sec[1]-1, ylim.sec[2]+1)
b <- diff(ylim.sec)/diff(ylim.prim)
}
if (is.na(b)){
ylim.prim <- c(ylim.prim[1]-1, ylim.prim[2]+1)
b <- diff(ylim.sec)/diff(ylim.prim)
}
ggplot(climate, aes(Month, Precip)) +
geom_col() +
geom_line(aes(y = ylim.prim[1]+(Temp-ylim.sec[1])/b), color = "red") +
scale_y_continuous("Precipitation", sec.axis = sec_axis(~((.-ylim.prim[1]) *b + ylim.sec[1]), name = "Temperature"), limits = ylim.prim) +
scale_x_continuous("Month", breaks = 1:12) +
ggtitle("Climatogram for Oslo (1961-1990)")
这里的关键部分是我们用
~((.-ylim.prim[1]) *b + ylim.sec[1])
变换辅助y轴,然后将反值应用于实际值y = ylim.prim[1]+(Temp-ylim.sec[1])/b)
。我们还应该确保limits = ylim.prim
。
