![]() ![]() Where region_colors.values() are all unique values from your DataFrame in the form of a dictionary with their colours. If you need to create a custom legend with multiple options you can use Python list comprehensions like: custom =, , marker='.', color=i, linestyle='None', markersize=25) for i in region_colors.values()] In order to plot the Scatterplot we generate 2 lists of random integers by: x = np.random.normal(0,1,15)Īnd list of random colors by: colors = Ĭustom Scatterplot legend with multiple options In this example, the last two scatter traces display on the second legend, 'legend2'. Specify more legends with legend'legend3', legend'legend4' and so on. For a second legend, set legend'legend2'. To have multiple legends, specify an alternative legend for a trace using the legend property. Next we set the legend labels, the font size and the legend position by: plt.legend(custom,, loc='upper left', fontsize=15) By default, all traces appear on one legend. Is shown in the legend and the automatic mechanism described aboveīy: custom =, , marker='.', markersize=20, color='b', linestyle='None'), Use this together with labels, if you need full control on what In order to create custom legend with Matplotlib and Scatterplot we follow next steps:įirst we start with creating the legend handles which are described as:Ī list of Artists (lines, patches) to be added to the legend. Notebook Explanation of custom Scatterplot legend If False, no legend data is added and no legend is drawn. Plt.legend(custom,, loc='upper left', fontsize=15) Draw a scatter plot with possibility of several semantic groupings. Line2D(,, marker='.', markersize=20, color='r', linestyle='None')] We will use the () method to describe and label the elements of the graph and distinguishing different plots from the same graph. import randomĬustom =, , marker='.', markersize=20, color='b', linestyle='None'), Then, add that legend to the ax with addartist. The example is showing a simple Scatterplot of few random points. First, change your legend declaration to the following legend1. Time series with filled area and custom facetting in Matplotlib: Shows how to create a legend with both lines and patches and how to place it in an arbitrary position in a visualization with multiple panels.In this short post you can find an example on how to add custom legend in Matplotlib and Python.The Office Ratings with Python and Matplotlib: Shows how to mimic a legend from scratch when built-in functions aren't enough.Mario Kart 64 World Records with Python and Matplotlib: Showcases how to put both a legend and a colormap. The Python matplotlib pyplot module has a function that will draw or generate a scatter plot, and the basic syntax to draw it is (x, y) x: list of arguments that represents the X-axis.Shows how to position a legend in a visualization with multiple panels and customize several aspects. Chris Claremont's X-Men comics exploration with streamcharts in Matplotlib: One of the most beautiful charts in this collection.Radar chart with Matplotlib: Shows how to manually overlay lines and dots in the same handle.Circular barplot with Matplotlib: Actually not a legend, but a colorbar with discrete scales that looks very cool. ![]() We have the penguins data on ’s github page. import pandas as pd import matplotlib.pyplot as plt We will use Palmer penguins data for making the scatter plot. ![]() ![]() Let us load Pandas and Matplotlib’s pyplot. Wouldn't it be really cool to see how these things are used in real-life examples? Of course it would! The following is a list of highly customized visualizations made in Matplotlib that contain beautiful legends made with the tricks shown above. In this tutorial, we will learn how to add right legend to a scatter plot colored by a variable that is part of the data. ![]()
