I have a data frame contain category, function and numbers.
>fun_category_df
sec_category sec_function `Number of Patents`
1 cleaning apparatus cleaning 2
2 cleaning apparatus enhance material removal 2
3 cleaning apparatus improve slurry distribution 2
4 detecting apparatus enhance material removal 6
5 detecting apparatus improve uniformity 6
6 dresser abrasive enhance material removal 5
7 dresser abrasive improve process stability 3
8 dresser abrasive improve quality 2
9 dresser abrasive improve uniformity 9
10 dresser structure improve uniformity 3
# ... with 38 more rows
I want to create a bubble chart base on my data frame. I have tried use ggplot2 to create it.
library(ggplot2)
bubble <- ggplot(fun_category_df,
aes(x =sec_category , y = sec_function , size = `Number of Patents`)) %>%
+ geom_point() + theme(axis.text.x = element_text(angle = 90, hjust = 1))
But the bubble only have 3 size to show.
How can I set the the bubble seize follow the "Number of Patents"?
Furthermore, I also want to tag number labels on each bubble. Like the following example.
