11.21 Bar Chart Wide and Borders
%>% ds ggplot(aes(wind_dir_9am)) + geom_bar(width=1, colour="blue", fill="grey") + scale_y_continuous(labels=comma) + labs(x=vnames["wind_dir_9am"], y="Count")
We can improve the appearance of a fat bar chart by adding, in this
case, a blue border to the bars, using
colour=``"blue". By itself
that would look a bit ugly, so we also
fill=``"grey" the bars with
grey rather than the default black. We can play with different colours
to achieve a pleasing and personalised result.
