Example 3: Add Labels to Some Points in ggplot2 Scatterplot In Example 3, I’ll explain how to specify labels only for some points that fall into a specific range. For this, we have to modify our label column using theifelse function: ggplot(data, aes(x, y, label=label))+# ggplot...

Sharon Machlis, IDG ggplot scatter plot with geom_label().These functions work well when points are spaced out. But if data points are closer together, labels can end up on top of each other — especially in a smaller graph. I added a fake data point close to Middlesex County in the...

3 ggplot2入门笔记3—通用教程如何自定义ggplot2 1. 添加图和轴标题(Adding Plot and Axis Titles) 2. 修改图例(Modifying Legend) 2.1 如何更改图例标题(How to Change the Legend Title) ...
2.1 如何更改图例标题(How to Change the Legend Title) 现在让我们更改图例标题。我们有两个图例,颜色和大小。大小基于连续变量,而颜色基于分类(离散)变量。有3种方法可以更改图例标题。 方法1:使用 labs() library(ggplot2)# Base Plotgg<-ggplot(midwest,aes(x=area,y=poptotal))+geom_point(aes(col=state...

>v<-ggplot(faithfuld,aes(waiting,eruptions,fill=density))>v+geom_tile() 小云来更改一些配色方案,我们可以设置为p1p3相同,p2p4相同,如下所示。 >v<-ggplot(faithfuld,aes(waiting,eruptions,fill=density))++geom_tile()>p1<-v+scale_fill_continuous(type="viridis")>p2<-v+scale_fill_continuous(type...
As shown in Figure 2, we have modified the text of the legend items with the previous R programming code. Note that the previous R code also change the color of the data points in our scatterplot.Example 2: Rename Factor Levels to Change Legend Labels of ggplot2 Plot...
