Plt.scatter(xi, yi, color=color, cmap=cm.plasma, label=str(unique)) To add a legend we use the plt.legend() function. On a sidenote, I also tried plotting each datapoint one by one with a for loop, as follows: # scatter strategy 2įor i, u, color in zip(range(len(unique)), unique, colors): This results in the legend not being displayed. Configurable legend shadows mathtext operators mathtext now supports \text matplotlib. However, you can change the marker colors using the color argument and the opacity by the. Just to discover that handles and labels are empty lists. In all our previous examples, you can see the default color of blue. Plt.legend(handles, labels, loc="lower right") import matplotlib.pyplot as plt fig, ax plt.subplots() ax.scatter(1, 2, label'point 1', color'r') ax.scatter(4, 3, label'point 2', color'b') ax.legend() for attr in dir(ax. Handles, labels = scatter1.legend_elements(num=list(np.unique(labels))) I’m trying to get the color of the markers in the legend, but it doesn’t seem like ax.getlegend() has a method for it. I run a (less than I thought) simple plt.scatter # scatter strategy 1 This is fine in the two-color case, but suppose I wanted to code them based on. I think the most elegant way is that suggesyted by. E.g.: import matplotlib.pyplot ( 1,2,3, 4,5,6,color 'red','green','blue') When you have a list of lists and you want them colored per list. I am trying to scatter some datapoints in matplotlib but am having some issues with displaying the legend properly.Īfter importing and initializing import matplotlib.pyplot as pltĬolors = The normal way to plot plots with points in different colors in matplotlib is to pass a list of colors as a parameter.
