Then, include the factor in your aesthetic, and geom_smooth() will do the rest of the work for you:test$latcat <- cut(test$lat, breaks = c(-Inf, 100, Inf), labels = c("<=100", ">100"))p <- ggplot( test, aes(lat, ecdf, colour = latcat))p + geom_point() + scale_y_probit() + scale_x_log10() +geom_smooth(method = "lm") 这篇关于将stat_smooth约束到特定的范围的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
