Title='Miles/(US) gallon vs Weight (1000 lbs)') + geom_point()+ geom_smooth() Title='Gross horsepower vs Rear axle ratio') + geom_point() + geom_density_2d()Ī regression line can be added using the geom_smooth() function. We can also plot a 2d density map using the geom_density_2d() function. The color, shape, and size values of the scatter plot can be dynamically changed using the variables of dataset. Title='Gross horsepower vs Rear axle ratio') + geom_point() + geom_text(label=df) We can also plot labels as points using the geom_text() function. Title='Miles/(US) gallon vs Weight (1000 lbs)') + geom_point(shape='x') The shape of the points in the plot also can be changed using the shape argument. Title='Miles/(US) gallon vs Weight (1000 lbs)') + geom_point(alpha = 0.5, size=5, color='blue') We can change the alpha, size, and color values of the points using arguments inside the geom_point() function. Title='Gross horsepower vs Rear axle ratio') + geom_point() Here’s another example of plotting of scatter plot. Title='Miles/(US) gallon vs Weight (1000 lbs)') + geom_point() Let’s plot a scatter plot using the geom_point() function. # importing packagesįrom plotnine import ggplot, aes, geom_point, labs, geom_text, geom_density_2d, geom_smoothįrom plotnine.data import mtcars Scatter plot using ggplot2 in Pythonįirst, use the Pandas head() method to select the first 50 rows of the mtcars dataset for simple visualizations. Import the required packages and the dataset. If you choose to use your local environment, then execute the below commands in your system. Refer to this article for ggplot2 installation in Python: ggplot2 installation guide Furthermore, I will use the mtcars dataset, which is also a built-in dataset of the plotnine package. The usage is also similar to that of ggplot2 in R.įor this tutorial, I will be using a google colab notebook which has the plotnine package preinstalled. It provides us with a grammar of graphics making the process of plotting efficient and easy. ggplot2 is a popular R data visualization package, and it can be used in Python using the plotnine package. In this tutorial, we will learn how to plot scatter plots in ggplot2 in Python. Scatter plots are great for visually seeing the relationship between numerical variables.
