Use the following code to arrive at our histogram: ggplot(mydata, aes(x=Girth)) + geom_histogram() Now, let’s plot the basic histogram to understand the distribution of the variable “Age”. . For ‘ylab’ we have ‘Number of Properties’. These cookies will be stored in your browser only with your consent. While we’re at it, some axis labels wouldn’t go amiss. Not to mention that in today’s data-driven world, a strong data visualization skillset is one of the gateways to a successful career in data science. A histogram plot is an alternative to Density plot for visualizing the distribution of a continuous variable. You also have the option to opt-out of these cookies.
