[英]ggplot color bar missing in legend
I am new to this forum, but i have found many answers searching through the threads. 我是这个论坛的新手,但是我在这些主题中找到了很多答案。 I am far from a programmer, but use R for creating custom graphs.
我离程序员还很远,但是使用R创建自定义图。 I have been climbing the learning curve, but hit a wall when trying to show 2 variables in a scatterplot, while desiring to show a third dimension Process_Time.
我一直在学习曲线,但是在试图显示散点图中的2个变量而又想显示第3维Process_Time时遇到困难。
I have filtered the rows of the dataset by "STATE" and so the "Process_Time" has breaks in it. 我已按“ STATE”过滤了数据集的行,因此“ Process_Time”已中断。
A summary of the dataframe is below: 数据框的摘要如下:
'data.frame': 71896 obs. of 10 variables:
$ key : Factor w/ 6 levels "ATAB","CCNa",..: 1 1 1 1 1 1 1 1 1 1
$ Process_Time: num 4.32 4.33 4.35 4.37 4.38 ...
$ CONC_PCT : num 30.9 31 31 30.9 30.9 ...
$ STATE : Factor w/ 4 levels "Blind","Gravimetric",..: 2 2 2 2 2 2 2
$ NW : num 1.15 1.14 1.14 1.14 1.13 ...
$ SRW_SP : num 106 105 105 106 105 ...
$ FF : num 2.45 2.46 2.46 2.45 2.45 ...
$ MF : num 15.5 15.5 15.5 15.4 15.4 ...
$ Max_Mass : num 1.72 1.72 1.72 1.72 1.72 ...
$ NW_norm : num 0.67 0.667 0.665 0.663 0.66 ...
The code is below: 代码如下:
FF_DATA <- subset(FF_Data, STATE=="Gravimetric")
FF_NW <- ggplot(FF_DATA,aes(NW_norm,FF)) +
geom_point(aes(color = Process_Time ))+
facet_grid(key~.,scales = "free")+
scale_color_gradient()
Maybe the issue is rendering gradients. 也许问题在于渲染渐变。 Try this, see if it works on your machine
尝试一下,看看它是否在您的机器上运行
library(ggplot2)
ggplot(mtcars, aes(x = wt, y = disp)) +
geom_point(aes(color = mpg)) +
facet_grid(gear~.,scales = "free")+
scale_color_gradient()
I saved with: ggsave("eg.png", type = "cairo")
我用以下
ggsave("eg.png", type = "cairo")
保存: ggsave("eg.png", type = "cairo")
It seems I have a rendering issue. 看来我有一个渲染问题。 I have read about this in a few other posts on the issue and have no idea where to start.
我已经在有关此问题的其他几篇文章中阅读了此内容,但不知道从哪里开始。
