• a more informative alternative to this barplot with errorbars
• using the movies example data set (part of the ggplot2 package)
• cut the year variable in 15 equal intervals gives the new variable years
• map this new year var to x, budget to y and colour also to years (aes(x=years,y=budget,colour=years))
• add a layer boxplot, set the fill colour for the bars to black
• format the y axis (use dollar formatting)
• change the x axis tick labels with a text theme: rotate the tick labels (angle=270), position adjustment with hjust and vjust
• we do not need a legend for he colours because the information is contained in the x axis, so get rid of it: opts(legend.position="none")
