How to draw Bubble Chart in R language
This article mainly explains "how to draw bubble charts with R language". The explanation content in this article is simple and clear, easy to learn and understand. Please follow the ideas of Xiaobian slowly and deeply to study and learn "how to draw bubble charts with R language" together.
The first step is to prepare the data.
Some of the data sets are as follows

4 columns in total
The first two columns are variables, the third column is correlation coefficients, and the fourth column is significant P values.
The variables in front need to be noted, because only the triangle is drawn, so the time to prepare the data is:
The total variables are 10 x1 's in the first column, followed by 9 x2 's, and then 8 x3 's.
Step 1 Tree reads data df%
mutate(label=case_when(
signi0.001&signi0.01&signi df1
And then there's the plot.
First up is the bubble diagram of the upper triangle.
library(ggplot2)
ggplot(data=df1,aes(x=var_x,y=var_y))+
geom_point(aes(size=value,color=value))+
scale_color_gradient(low = "#80fcfe",high = "#ff80fc",
breaks=seq(-1,1,0.2))+
scale_size_continuous(range = c(5,15))+
guides(size=F)

In this case, X10 is not in the right position, so set the level of the factor
df1$var_x df2
head(df2)
ggplot(data=df1,aes(x=var_x,y=var_y))+
geom_point(aes(size=value,color=value))+
scale_color_gradient(low = "#80fcfe",high = "#ff80fc",
breaks=seq(-1,1,0.2))+
scale_size_continuous(range = c(5,15))+
guides(size=F)+
theme_bw()+
geom_text(data=df2,aes(x=var_y,y=var_x,
label=paste0(value,label)))

Finally adjust the legend height
df1%>%
filter(var_x!= var_y) -> df2
head(df2)
ggplot(data=df1,aes(x=var_x,y=var_y))+
geom_point(aes(size=value,color=value))+
scale_color_gradient(low = "#80fcfe",high = "#ff80fc",
breaks=seq(-1,1,0.2))+
scale_size_continuous(range = c(5,15))+
guides(size=F)+
theme_bw()+
geom_text(data=df2,aes(x=var_y,y=var_x,
label=paste0(value,label)))+
theme(legend.key.height = unit(3.5,'cm'),
legend.justification = c(0,0),
legend.title = element_blank())
Thank you for reading, the above is "how to draw bubble diagram with R language" content, after the study of this article, I believe we have a deeper understanding of how to draw bubble diagram with R language, the specific use of the situation also needs to be verified by practice. Here is, Xiaobian will push more articles related to knowledge points for everyone, welcome to pay attention!
