Figure 2: ggplot2 Line Graph with Thick Line. If NULL, the default, the data is inherited from the plot data as specified in the call to ggplot(). We can increase the labels of our plot axes with the cex.lab argument: plot(x, y, # Increase label size
# Box plot : change y axis range bp + ylim(0,50) # scatter plots : change x and y limits sp + xlim(5, 40)+ylim(0, 150) Use expand_limts() function. Note that I always specified the cex arguments to be equal to 3. You can find the video below. Create a scatter plot and change point shapes using the argument shape: library(ggplot2) # Basic scatter plot ggplot(df, aes(x=wt, y=mpg)) + geom_point() # Change the point shape ggplot(df, aes(x=wt, y=mpg)) + geom_point(shape=18) # change shape, color, fill, size ggplot(df, aes(x=wt, y=mpg)) + geom_point(shape=23, fill="blue", color="darkred", size=3) I've tried adjust with width/height but doesn't scale properly.

For example, if we have a data frame called df that contains a column x for which we want to create the dotplot then the plot with different size of dots can be created by using the command ggplot(df,aes(x))+geom_dotplot(binwidth=2). However, it remains less flexible than the function ggplot().. In conjunction with the theme system, the element_ functions specify the display of how non-data components of the plot are drawn. To plot a function, we should specify the function under stat_function in ggplot. This function is a thin wrapper around geom_blank() that makes it easy to add such values.
