11.28 Faceted Location Thin Lines
## Warning: Using `size` aesthetic for lines was deprecated in ggplot2 3.4.0. ## ℹ Please use `linewidth` instead.
%>% ds ggplot(aes(x=date, y=max_temp)) + geom_line(alpha=0.1, size=0.05) + geom_smooth(method="gam", formula=y~s(x, bs="cs"), size=0.05) + facet_wrap(~location) + theme(axis.text.x=element_text(angle=45, hjust=1)) + labs(x=vnames["date"], y=vnames["max_temp"])
An alternative is to present the plot as a line chart rather than a scatter plot. It does make more sense for a time series plot such as this, though the effect is little changed due to the amount of data being displayed.
Changing to lines simply uses ggplot2::geom_line() instead of ggplot2::geom_point(). Very thin lines are used as specified through the size= option. Nonetheless, the data remains quite dense.
