![]() ![]() What we can do is pass in that cut category using the hue parameter as hue=’cut’. For example, we know that our data has a cut for our diamond. We can also utilize some of our categorical variables to improve our visuals. You can play around with the parameters to get the best visual you are looking for. If we add these parameters and click on Run, you can see our scatter plot gets more opaque without the white lines. But of course, you could change that to 0.1 as well. We also want to adjust the alpha so we can control the opacity. Let’s dive in a little bit. We can make the linewidth=0 because the white lines in our first scatter plot, shown below, somewhat obscure things. Scrolling further down will give us information on what each one of the listed parameters does. It will show us a list of different parameters that we can add to our scatter plot. We can press the Shift + Tab keys to see the different ways to style the scatter plot. That’s because we have about 54,000 rows of data and the points are not necessarily represented in the best way. You can see that this scatter plot is quite dense. Here’s our scatter plot made with the Seaborn library. Then, we identified the X and Y variables- carat and price, respectively. Thus, using the Seaborn library, we’ve created our scatter plot using the scatter plot function where we passed in the data we saved above as data=dataset. When visualizing correlations and looking at two variables, we usually look at scatter plots. Python Correlation: Creating A Scatter Plot We have carat in the first column, followed by the categorical variables cut, color, and clarity, and then numerical values for the rest of the data. The Python Correlation Datasetīy using the function head written as dataset.head, we can get the top five rows of our data which should look like this. However, we will also learn how to utilize some of the categorical variables for visualization. Note that correlation only works on numerical variables, thus, we are going to look at the numerical variables most of the time. This function shows us all the different data types as seen in the last column below. We can view the attributes of our data using function. ![]() Then using the sns variable, we will bring in the diamonds dataset as shown below. And lastly, Numpy, to be saved as np, will be used for linear algebra.įor the data, we will use a sample dataset in Seaborn. Seaborn, our statistical visualization library, will be saved as sns. Our first package is Pandas to be used for data manipulation and saved as variable pd.įor visualization, we will use Matplotlib, saved as plt variable for easier use of these functions. We will be using four packages for this tutorial. The rightmost graph is the perfect negative correlation which has a correlation value of -1. The middle graph shows no correlation suggesting a correlation value equal to 0.įinally, the right hand side presents decreasing negative correlations values from 0. Then, it is followed by positive correlations in descending order leading to 0. Starting from the left, we have the perfect positive correlation which means it has a correlation value of 1. Here’s a nice image showing the different types of correlations.
