我想製作一個熱圖,它創建一組清晰度爲&的顏色組合作爲X軸並切割爲Y軸。熱圖將基於清晰度+顏色的計數以及其與切割的交點進行着色。Ggplot熱圖 - 用於定製計數範圍的自定義顏色
library(ggplot2)
library(dplyr)
## rename diamonds df
# 1. Generate a count for the frequency of cut+clarity
# 2. Make a heatmap of this using the following bins
# 3. Red <= 100 Frequency
Yellow = between (100 and 500)
Green > 500
# place counts inside the cell:
df = diamonds %>%
select(cut, clarity) %>%
group_by(cut,clarity)%>%
mutate(count = n())
myplot = ggplot(df, aes(x = clarity, y=cut)) +
geom_bin2d(bins = c(100,500,50000), col='orange') #
geom_text(aes(label = count),col='red')
myplot
使用'切()'爲 「離散化」 的連續變量,然後使用自定義比例指定這樣你的顏色這樣的問題:HTTP ://stackoverflow.com/questions/26103140/how-can-i-create-a-custom-colour-scale-using-ggplot2-and-geom-tile/26103786#26103786或這一個:http:// stackoverflow。 COM /問題/ 10981324/GGPLOT2-熱圖與 - 顏色換範圍值/ 10982332#10982332。不要打擾geom_bin2d,這對分箱x和y值非常有幫助,但您已經有了離散值。 – MrFlick
