The Python matplotlib pyplot scatter plot is a two-dimensional graphical representation of the data. Example to Implement Matplotlib Scatter Finally, let us take an example where we have a correlation between the variables: Example #1 Here we will define 2 variables, such that we get some sort of linear relation between them a = [8,10, 14, 12,20,25,30, 44, 48,52, 32, 30,44, 40, 55,50] Step 3: Use Pandas scatter_matrix Method to Create the Pair Plot. So that's why it is called as scatter marker. For those who do not want to define their own functions, there is a great data analysis libarary in Python, called Pandas, where one can find the scatter_matrix() method: Generally speaking, matplotlib doesn't usually contain plotting functions that operate on more than one axes object (subplot, in this case).

[FIX #1] The axis tics weren't lining up like I would expect (i.e., in your example above, you should be able to draw a vertical and horizontal line through any point across all plots and the lines should cross through the corresponding point in the other plots, but as it sits now this doesn't occur. scatter_matcix scatter_matrix Register as a new user and use Qiita more conveniently You get articles that match your needs You can efficiently read back useful information What you can do with signing up a = np.random.rand(A) What is the use of NTP server when devices have accurate time?
