Any parameter that geom_line() , geom_histogram() , geom_boxplot() , or geom_violin() accepts can be used. 4 Font ordinate. Lessons learned. The visual way that the data is represented forms another component of the grammar of graphics. Similarly, all plots have data represented between the axes, often as points, lines or bars. Highlight the top line with geom_line() If not too many observation, show individual data points with geom_point() library (plotly) set. A boxplot is composed of several elements: The line that divides the box into 2 parts represents the median of the data. ggplot(data=dat1, aes(x=time, y=total_bill, group=sex, shape=sex, colour=sex)) + geom_line(aes(linetype=sex), size=1) + geom_point(size=3, fill="white") + expand_limits(y=0) + scale_colour_hue(name="Sex of payer", l=30) + scale_shape_manual(name="Sex of payer", values=c(22,21)) + scale_linetype_discrete(name="Sex of payer") + xlab("Time of day") + ylab("Total bill") + ggtitle("Average bill for 2 people") + theme_bw() + theme(legend.
