Seaborn automatically represents the third variable with the legend describing colors to the plot. Plt.savefig("Color_scatterplot_by_variable_with_hue_Seaborn_scatterplot.png",īy coloring data points by a variable in the scatter plot, we have added third variable to the plot. In this example, we have colored the data points by the “species” variable using hue=”species”. We can change the colors of data points on the scatter plot by a variable in the dataframe using “hue” argument in Seaborn’s scatterplot() function. How To Color Scatter Plot by a Variable with Seaborn’s scatterplot()? Customize Axis Labels: Seaborn Scatterplot 6. We have customized the x-axis and y-axis labels and also increased label’s font sizes. Plt.savefig("Customize_Axis_Labels_Scatter_Plot_Penguins_data_Seaborn.png", Plt.ylabel("Flipper Length (mm)", size=24) Plt.xlabel("Culmen Length (mm)", size=24) We use Matplotlibs’ xlabel() and ylabel() functions to change the labels and increase their font sizes. We can change the axis labels and their sizes using Matplotlib. Notice that, our x and y axis labels are the same names as in Penguin’s data frame. How To Change Axis Labels and Size with Matplotlib for Seaborn Scatterplot? How To Change Marker Size in Seaborn Scatterplot? 5. Now the data points on the scatter plot is bigger and clearly visible. Plt.savefig("How_To_Change_Marker_Size_Seaborn_ScatterPlot.png", We can increase the marker size or the data point size in the scatter plot using the argument “s” in Seaborn’s scatterplot() function. Sns.set_context("notebook", font_scale=1.5) # Set common plotting_context for all the plots Earlier we used “with” statement to set plotting_context for a single scatter plot. How To Change Marker Size in Seaborn Scatterplot?īefore changing the marker size, let us set the axis tick label size for all the plots in the notebook/script. Increase Axis Label Size: Seaborn scatterplot() 4. Now we have a better looking scatter plot between Penguin’s Culmen length and Flipper Length with easily readable axis tick labels. With sns.plotting_context("notebook",font_scale=1.5): # Increase axis tick label with plotting_context in Seaborn In this example, we use plotting_context() function with the arguments ‘”notebook”,font_scale=1.5’. We can increase Axes tick labels using Seaborn’s plotting_context() function. How To Increase Axes Tick Labels in Seaborn?Īlthough we have increased the figure size, axis tick labels are tiny and not easy to read. How To Change Figure Size Seaborn Scatterplot? 3. In the example here, we have specified the figure size with figsize=(10,8). To increase the figure size, we can use Matplotlib’s figure() function and specify the dimension we want. We might want to increase the figure size and make the plot easier to look at. By default, Seaborn creates a plot of certain size. How To Increase Figure Size with Matplotlib in Python?Ī look at the scatter plot suggests we can improve the simple version a lot. Simple Scatter Plots with Seaborn scatterplot 2. We can use Seaborn’s scatterplot() specifying the x and y-axis variables with the data as shown below.Īnd we get a simple scatter plot like this below. First, we will make a simple scatter plot between two numerical varialbles from the dataset,culmen_length_mm and filpper_length_mm. Let us get started making scatter plots with Penguin data using Seaborn’s scatterplot() function. How To Make Simple Scatter Plot with Seaborn’s scatterplot()? The dataset contains body measurements of three Penguin species.ġ. It is a great dataset to teach data exploration and data visualization. Palmer Penguins DatasetWe will learn to make scatter plots using the wonderful new dataset on Penguins from Palmer station. One of the benefits of using scatterplot() function is that one can easily overlay three additional variables on the scatterplot by modifying color with “hue”, size with “size”, and shape with “style” arguments. Seaborn’s scatterplot() function is relatively new and is available from Seaborn version v0.9.0 (July 2018). In this tutorial, we will use Seaborn’s scatterplot() function to make scatter plots in Python. With Seaborn in Python, we can make scatter plots in multiple ways, like lmplot(), regplot(), and scatterplot() functions. Often we can add additional variables on the scatter plot by using color, shape and size of the data points. Seaborn scatterplot()Scatter plots are great way to visualize two quantitative variables and their relationships.
