It is a most basic type of plot that helps you visualize the relationship between two variables. Scatter plot needs arrays for the same length, one for the value of x-axis and other value for the y-axis. A Python scatter plot is useful to display the correlation between two numerical data values or two data sets. For example, if you want to examine the relationship between the variables “Y” and “X” you can run the following code: sns.scatterplot(Y, X, data=dataframe).There are, of course, several other Python packages that enables you to create scatter plots. We will learn about the scatter plot from the matplotlib library. Scatter plots are useful when you want to find a relation between two numeric variables. Adding Titles and Labels to Seaborn in Python. How to use plot_with_labels()? 2.When i set c= km.labels_ instead, i get the error: ValueError: Color array must be two-dimensional.
