ggplot2 multiple stat_smooth:改变颜色&线型 [英] ggplot2 multiple stat_smooth: change color & linetype
问题描述
我无法使用多个更平滑的( stat_smooth())来更改当前绘图的颜色和线型。
的数据结构:
serviceInstanceName时间戳值
1 DE1Service-utilityPredicted 2014-02-22 10.000000
2 SE1Service-utilityPredicted 2014-02-22 4.385694
3 DE2Service-utilityPredicted 2014-02-22 0.000000
4 US1Service-utilityPredicted 2014-02-22 2.230000
5 DE1Service-utilityActual 2014-02- 22 10.000000
6 SE1Service-utilityActual 2014-02-22 8.011919
7 DE2Service-utilityActual 2014-02-22 3.000000
8 US1Service-utilityActual 2014-02-22 1.325191
.. 。
根据时间戳(y轴)和值(x轴),有八个独特的服务实例。
这里的代码:
ggplot(rmm,aes(x =恬estamp,y = value,color = serviceInstanceName,group = serviceInstanceName))
+ stat_smooth(size = 1.5,method =loess,level = 0.95,fullrange = TRUE,se = FALSE)
+ scale_x_datetime (break = date_breaks(1 day),labels = date_format(%a /%m))
+ theme(axis.text.x = element_text(angle = 90,hjust = 1))+ xlab (Day)
+ ylab(Utility)+ ggtitle(Utility Trend)
这里的情节:
我想要的:
=>手动更改每个唯一* serviceInstanceName属性值的线型和颜色。我尝试了很多来自 scale_color_manual()的东西,直到提取平滑器的值..但实际上无法解决这个问题。
任何帮助表示赞赏。谢谢!
好吧,您的数据并不适合重新创建剧情,所以我创建了一个不同的示例数据集 p>
rmm <-data.frame(
timestamp = as.POSIXct(rep(seq(as.Date(2014- ),
as.Date(2014-01-10),by =1 day),5)),
serviceInstanceName = rep(letters [1:5],每个= 10),
值= cumsum(rnorm(50))
)
我不确定你试过的是什么,但是 scale_color_manual
应该可以工作。如果您想更改线型,您需要在 aes()
中设置该线型
$ b
library(ggplot2)
library(scales)
ggplot(rmm,aes(x = timestamp,y = value,
color = serviceInstanceName,linetype = serviceInstanceName))+
stat_smooth(size = 1.5,method =loess,level = 0.95,
fullrange = TRUE,se = FALSE)+
scale_x_datetime(breaks = date_breaks(1 day ),
labels = date_format(%a /%m))+
theme(axis.text.x = element_text(angle = 90,hjust = 1))+ xlab(Day )+
ylab(Utility)+ ggtitle(效用趋势)+
scale_color_manual(值= c(a =orange,b =yellow,
c =red ,d =sienna,e =cornsilk))
I am not able to change the colors and linetypes of my current plot with multiple smoother ( stat_smooth())
Here an overview of the data structure:
serviceInstanceName timestamp value
1 DE1Service-utilityPredicted 2014-02-22 10.000000
2 SE1Service-utilityPredicted 2014-02-22 4.385694
3 DE2Service-utilityPredicted 2014-02-22 0.000000
4 US1Service-utilityPredicted 2014-02-22 2.230000
5 DE1Service-utilityActual 2014-02-22 10.000000
6 SE1Service-utilityActual 2014-02-22 8.011919
7 DE2Service-utilityActual 2014-02-22 3.000000
8 US1Service-utilityActual 2014-02-22 1.325191
...
There are eight unique service instances with according timestamp (y axis) and value (x axis).
Here the code:
ggplot(rmm, aes(x=timestamp, y=value, color=serviceInstanceName, group=serviceInstanceName))
+ stat_smooth(size=1.5, method = "loess", level = 0.95, fullrange = TRUE, se = FALSE)
+ scale_x_datetime(breaks = date_breaks("1 day"), labels = date_format("%a/%m"))
+ theme(axis.text.x = element_text(angle = 90, hjust = 1)) + xlab("Day")
+ ylab("Utility") + ggtitle("Utility Trend")
Here the plot:
What I want:
=> To manually change the linetypes and colors of each unique *serviceInstanceName' attribute value. I tried many things from scale_color_manual() .. until extracting the value of the smoother.. but really could not solve this.
Any help is appreciated. Thanks!
Well, your data wasn't that hlpeful for recreating the plot so i created a different sample data set
rmm<-data.frame(
timestamp = as.POSIXct(rep(seq(as.Date("2014-01-01"),
as.Date("2014-01-10"), by="1 day"),5)),
serviceInstanceName = rep(letters[1:5], each=10),
value = cumsum(rnorm(50))
)
And i'm not sure exactly what you tried, but scale_color_manual
should have worked. And if you want to change the line type you need to set that in the aes()
library(ggplot2)
library(scales)
ggplot(rmm, aes(x=timestamp, y=value,
color=serviceInstanceName, linetype=serviceInstanceName)) +
stat_smooth(size=1.5, method = "loess", level = 0.95,
fullrange = TRUE, se = FALSE) +
scale_x_datetime(breaks = date_breaks("1 day"),
labels = date_format("%a/%m")) +
theme(axis.text.x = element_text(angle = 90, hjust = 1)) + xlab("Day") +
ylab("Utility") + ggtitle("Utility Trend") +
scale_color_manual(values=c(a="orange",b="yellow",
c="red", d="sienna",e="cornsilk"))
