我想改变颜色方案......并希望将颜色分为3类:
我尝试了以下内容:
ggplot_calendar_heatmap(
prod,
'REPORT_DATE',
'PROD'
) +
xlab('') +
ylab('') +
scale_fill_continuous(low = 'red', high = 'green') +
facet_wrap(~Year, ncol = 1)
还试图使用scale_colour_gradientn
和scale_colour_manuel
,但没有运气......任何想法?
答案 0 :(得分:2)
这样的事情应该有效:
set.seed(1)
# generate some random data
prod <- data.frame(REPORT_DATE=seq.Date(as.Date('2015/01/03'), as.Date('2017/02/28'), by='day'))
prod$PROD <- runif(nrow(prod), 0, 5)
prod <- transform(prod, PROD.cut=cut(PROD, breaks=c(-Inf,3, 3.2,Inf))) # bin data
library(ggTimeSeries)
ggplot_calendar_heatmap(
prod,
'REPORT_DATE',
'PROD.cut'
) +
xlab('') +
ylab('') +
scale_fill_manual(values = c("red", "orange", "green")) +
#scale_fill_continuous(low = 'red', high = 'green') +
facet_wrap(~Year, ncol = 1)
