Matplotlib scatter has a parameter c which allows an array-like or a list of colors. to be shown and return a tuple of handles and labels. A Python scatter plot is useful to display the correlation between two numerical data values or two data sets. The following also demonstrates how transparency of the markers The size is then indicated from the output of the scatterfunction, using legend_elementsfor the sizes. To set the color of markers in Matplotlib, we set the c parameter in matplotlib.pyplot.scatter() method.. Set the Color of a Marker in the Scatterplot import matplotlib.pyplot as plt x=[1,2,3,4,5,6,7] y=[2,1,4,7,4,3,2] plt.scatter(x,y,c="red") plt.xlabel("X") plt.ylabel("Y") plt.title("Simple Scatter Plot") plt.show() The Python matplotlib scatter plot is a two dimensional graphical representation of the data. Experience. To create a scatter plot with a legend one may use a loop and create one The edge color of the marker. PR Summary This PR proposes to include an easy, yet versatile option to create legends for scatterplots. Other keyword arguments are passed down to matplotlib.axes.Axes.scatter(). Colormap instances are used to convert data values (floats) from the interval [0, 1] to the RGBA color that the respective Colormap represents. (I agree that this is a bit confusing, but the "c" and "s" terminology is inherited from matlab, in this case.) The usage of the following functions and methods is shown in this example: Keywords: matplotlib code example, codex, python plot, pyplot The following also demonstrates how transparency of the markers can be adjusted by giving alpha a value between 0 and 1.
