我想创建带有鲜明色彩的plotly
条形图。
我已经找到了如何通过变量调整颜色缩放,但不知道如何选择另一个托盘。我想以RBrewerPallet
为例。
这是一个例子。
library(plotly)
library(dplyr)
airquality %>% group_by(Month) %>% summarise(total = sum(Wind)) %>%
plot_ly(x = ~Month,
y = ~total,
type = 'bar',
marker = list(
color = ~total
))
答案 0 :(得分:3)
这是一种在曲线图中指定条形图的颜色比例的方法:
library(plotly)
library(dplyr)
airquality %>% group_by(Month) %>% summarise(total = sum(Wind)) %>%
plot_ly(x = ~Month,
y = ~total,
type = 'bar',
marker = list(
color = ~total,
colorscale='Blues'
))
我知道这些托盘:" Blackbody"," Bluered"," Blues"," Earth"," Electric& #34;," Greens"," Grays"," Hot"," Jet"," Picnic",& #34; Portland"," Rainbow"," RdBu"," Reds"," Viridis"," YlGnBu&# 34;," YlOrRd"。
如果还不够,您可以手动指定:
marker = list(color = c('rgba(204,204,204,1)', 'rgba(222,45,38,0.8)',
'rgba(204,204,204,1)', 'rgba(204,204,204,1)',
'rgba(204,204,204,1)')
