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 import aphobjects as go from plotly.subplots import makesubplots fig makesubplots(rows2, cols2, startcell'bottom-left') fig.addtrace(go.Scatter(x1, 2, 3, y4, 5, 6), row1, col1) fig.addtrace(go.Scatter(x20, 30, 40, y50, 60, 70), row1, col2) fig.addtrace(go.Scatter(x300, 400, 500, y600, 700, 800), row2. Next we set the legend labels, the font size and the legend position by: plt.legend(custom,, loc='upper left', fontsize=15) Is shown in the legend and the automatic mechanism described aboveīy: custom =, , marker='.', markersize=20, color='b', linestyle='None'), In this example I used their own subset of country level life expectancy dataset via gapminder to show how data in multiple subplots could have their own legend.

Use this together with labels, if you need full control on what Solution: I found that Plotly's subplot functionality has two parameters that I could use to fake having an individual legend per subplot. 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. You can use the following syntax to add a legend to a scatterplot in Matplotlib: import matplotlib.pyplot as plt from lors import ListedColormap define values, classes, and colors to map values 0, 0, 1, 2, 2, 2 classes 'A', 'B', 'C' colors ListedColormap ( 'red', 'blue', 'purple') create scatterplot scatter plt. Notebook Explanation of custom Scatterplot legend To create a scatter plot with a legend one may use a loop and create onescatterplot per item to appear in the legend and set the labelaccordingly. Plt.legend(custom,, loc='upper left', fontsize=15)

New to Plotly Automatic Labelling with Plotly Express Plotly Express is the easy-to-use, high-level interface to Plotly, which operates on a variety of types of data and produces easy-to-style figures.

import randomĬustom =, , marker='.', markersize=20, color='b', linestyle='None'), Setting the Font, Title, Legend Entries, and Axis Titles in Python How to set the global font, title, legend-entries, and axis-titles in python. The following also demonstrates how transparency of the markerscan be adjusted by giving alphaa value between 0 and 1. The example is showing a simple Scatterplot of few random points. To create a scatter plot with a legend one may use a loop and create onescatterplot per item to appear in the legend and set the labelaccordingly. In this short post you can find an example on how to add custom legend in Matplotlib and Python.
