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()] You can visualize more than two variables on a two-dimensional scatter plot by customizing the markers. 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 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'), Setting to False will draw marker-less lines. Setting to True will use default markers, or you can pass a list of markers or a dictionary mapping levels of the style variable to markers. Use this together with labels, if you need full control on what Object determining how to draw the markers for different levels of the style variable. 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 It is used both by the marker functionality of the plot and scatter. Plt.legend(custom,, loc='upper left', fontsize=15) The matplotlib.dates module provides functions to handle markers in Matplotlib. So, if we want to change the style of the marker, we can change it through this parameter. The coordinates of each point are defined by two dataframe columns and filled circles are used to represent each point. This kind of plot is useful to see complex correlations between two variables. Create a scatter plot with varying marker point size and color. Line2D(,, marker='.', markersize=20, color='r', linestyle='None')] By default, the marker is a solid round, as shown in the above output. Markers in Matplotlib Markers in Matplotlib Brandon Rohrer part of Course 133 Navigating Matplotlib ax.scatter (x, y, s80) sizes np.random.sample (sizex.size) ax. Create a scatter plot with varying marker point size and color. import randomĬustom =, , marker='.', markersize=20, color='b', linestyle='None'), ![]() The example is showing a simple Scatterplot of few random points. In this short post you can find an example on how to add custom legend in Matplotlib and Python.
