get dimension of scatter plot matplotlib

Matplotlib’s plt.plot() is a general-purpose plotting function that will allow you to create various different line or marker plots. You can also produce the scatter plot shown above using another function within matplotlib.pyplot. You can then carry out further analysis, whether it’s using linear regression or other techniques. When using scatter plots in this way, close inspection can help you explore the relationship between variables. However, the drink that costs $4.02 is an outlier, which may show that it’s a particularly popular product. This plot shows that, in general, the more expensive a drink is, the fewer items are sold. In this tutorial, all the examples will be in the form of scripts and will include the call to plt.show(). When you’re using an interactive environment, such as a console or a Jupyter Notebook, you don’t need to call plt.show(). As you’re using a Python script, you also need to explicitly display the figure by using plt.show(). You then create lists with the price and average sales per day for each of the six orange drinks sold.įinally, you create the scatter plot by using plt.scatter() with the two variables you wish to compare as input arguments. This alias is generally used by convention to shorten the module and submodule names. In this Python script, you import the pyplot submodule from Matplotlib using the alias plt. Import matplotlib.pyplot as plt price = sales_per_day = plt.

You don’t need to be familiar with Matplotlib to follow this tutorial, but if you’d like to learn more about the module, then check out Python Plotting With Matplotlib (Guide). To get the most out of this tutorial, you should be familiar with the fundamentals of Python programming and the basics of NumPy and its ndarray object. Represent more than two dimensions on a scatter plot.Customize scatter plots for basic and more advanced plots.Use the required and optional input parameters.Create a scatter plot using plt.scatter().Matplotlib provides a very versatile tool called plt.scatter() that allows you to create both basic and more complex scatter plots.īelow, you’ll walk through several examples that will show you how to use the function effectively. One of the most popular modules is Matplotlib and its submodule pyplot, often referred to using the alias plt.

Python has several third-party modules you can use for data visualization.
