You can use matplotlib to create complex visualizations, because the syntax is very detailed. Some of those data visualizations can be extremely complex. It provides Python users with a toolkit for creating data visualizations. Matplotlib is a data visualization module for the Python programming language.

Before I show you how to make a scatter plot with matplotlib, let me quickly explain what matplotlib is. Everything will make more sense that way.

Examples of how to make a scatter plot with matplotlibĪgain though, if you’re a relative beginner and you have the time, I recommend that you read the full tutorial.The syntax for the matplotlib scatter plot.These links will bring you to the appropriate section in the tutorial. Having said that, if you just need quick help with something, you can click on one of the following links.

Ideally, it’s best if you read the whole tutorial. Overall, the tutorial is designed to be read top to bottom, particularly if you’re new to Python and want the details of how to make a scatter plot in Python. This tutorial will show you how to make a matplotlib scatter plot, and it will show you how to modify your scatter plots too. You should know how to do this with your eyes closed.

Having said that, if you want to do data science in Python, you really need to know how to create a scatter plot in matplotlib. The scatter plot is a relatively simple tool, but it’s also essential for doing data analysis and data science. This works, of course, also for continuous data: from matplotlib import pyplot as pltĭf = pd.In this tutorial, I’ll show you how to make a matplotlib scatter plot.

Plt.scatter(5, 5, marker=MarkerStyle('o', fillstyle='bottom'), edgecolors='k', s=500)Īs mentioned in the comments, I don't see why you have to use plt.scatter but if you want to, you can fake a combined marker: from matplotlib.markers import MarkerStyleĭf = pd.DataFrame()Īx.scatter(df.X, df.Y, s=df.S, c=df.C1, edgecolor='black', marker=MarkerStyle('o', fillstyle='right'))Īx.scatter(df.X, df.Y, s=df.S, c=df.C2, edgecolor='black', marker=MarkerStyle('o', fillstyle='left')) Plt.scatter(4, 4, marker=MarkerStyle('o', fillstyle='top'), edgecolors='k', s=500) Plt.scatter(3, 3, marker=MarkerStyle('o', fillstyle='right'), edgecolors='k', s=500) Plt.scatter(2, 2, marker=MarkerStyle('o', fillstyle='left'), edgecolors='k', s=500) Plt.scatter(1, 1, marker=MarkerStyle('o', fillstyle='full'), edgecolors='k', s=500)

I'm able to get following output using the code below.įrom matplotlib.markers import MarkerStyle I've been using, but that seems to only get me halfway there. That is to say, instead of a half-filled marker, the plot shows half of a marker.

I can't seem to make half-filled markers properly using a scatter plot. (I believe this will be easier with a scatter plot since I want to automate making a large number of plots from a large data set.) I know half-filled markers can easily be done using a line plot, but I would like to use 'scatter' because I want to use marker size and color (i.e., alternate marker face color) to represent other data. Question: Using a scatter plot in matplotlib, is there a simple way get a half-filled marker?
