I have a chart drawn by geom_point using the code below. Is it normal that the confidence band does not cover the entire chart? I am using loess
method:
ggplot(data,aes(x=Year_Month, y=CNT, group=1)) +
geom_line(stat="identity", size=2, alpha=0.7, color="#00a9ff") +
geom_point(size=5, color="#2787db") +
geom_smooth(method = 'loess', color="red") +
scale_y_continuous(breaks=seq(0,mx,5), limits = c(-2,mx)) +
geom_text(label=data$CNT, vjust=-2, color="blue")
