Geom_hline(yintercept = -log10(5e-8), color = "black", linetype = "dashed", It takes two arguments: label: title of the plot subtitle: subtitle of the plot ggplot(mtcars) + geompoint(aes(disp, mpg)) + ggtitle(label 'Displacement vs Mileage', subtitle 'disp vs mpg') 4. ![]() ![]() # geom_hline(yintercept = -log10(1e-5), color = "red", linetype = "dashed", Let us explore the ggtitle () function first.

Some peaks are very close together, so the labels will end up being pushed up the y axis so they are able to stack up neatly. I have created a separate object as a master x-axis title spanning the graphs using ggdraw() and drawlabel(. I would then like the label to sit on top of this horizontal section of the line. I am creating a large 2 x 4 multi-graph panel using the packages described in the title. I would like the lines connecting the labels to be directly above each peak on the x axis, then turn at a right angle and the line continue horizontally slightly. The plot has multiple peaks that need labelling. I cannot share the data unfortunately, but I have inserted one of my codes below. I have tried using various geom_label_repel and geom_text_repel options but am not having much luck. The labels do not look neat and tidy due to their positioning. I am trying to add labels to a ggplot object. ![]()
