We get a nice colored bubble plot made with matplotlib. Plt.title("Bubble Plot with Colors: Matplotlib", size=18) Here, Colors is the quantitative variable that we created when we constructed the dataframe. And we use the argument c=”Colors” to color the bubble by a variable. The scatter() function has the argument “c” for specifying colors. Let us color the bubbles differently using another variable in the bubble plot. Simple Bubble Plot in Python with Matplotlib Color Bubble Plot By Variable in Python We have also added transparency to the bubbles in the bubble plot using alpha=0.5. By default, Matplotlib makes the bubble color as blue. We can see that the points in the scatter plots are bubbles now based on the value of size variable. Plt.title("Bubble Plot with Matplotlib", size=18) To make bubble plot, we need to specify size argument “s” for size of the data points. Using Matplotlib, we can make bubble plot in Python using the scatter() function. 2 Color Bubble Plot By Variable in Python.Our customized scatter plot looks like this.

Plt.title("Scatter Plot with Matplotlib", size=18) We also add a title to the scatter plot using plt.title(). Here we customize the axis labels and their size using xlabel and ylabel functions. The x and y-axis label sizes are smaller by default, when we make scatter plot using scatter function(). Let us first make a simple scatter plot with Matplotlib using scatter() function. The scatter plot can then be analyzed to look for patterns and trends. To create a scatter plot, the data points are plotted on a coordinate grid, and then a line is drawn to connect the points. Here we construct dataframe from NumPy arrays using Pandas’ DataFrame function and providing the variables as a dictionary. Detect outliers: Scatter plots are often used to detect outliers, or data points that lie outside the general trend.
CREATE A SCATTER PLOT MATPLOTLIB INSTALL
You’ll need to install and then import the pandas module, in addition to the matplotlib module.Let us store the simulated data in a Pandas dataframe. Let’s first take an example so we can explain its structure better. Such a plot creates a box-and-whisker plot and summarizes many different numeric variables. Another use is to analyze how distributed data is across datasets. Create Scatter Plot using Pandas DataFrameĪnother way in which you can capture the data in Python is by using pandas DataFrame. Python box plot tells us how distributed a dataset is.
CREATE A SCATTER PLOT MATPLOTLIB HOW TO
Let’s now see how to create the exact same scatter plot, but only this time, we’ll use pandas DataFrame. Those types of diagrams can help you determine if there is a linear relationship between the variables – a necessary condition to fulfill before applying linear regression models. Scatter diagrams are especially useful when applying linear regression. You may notice that a negative relationship exists between those two variables, meaning that when the Unemployment Rate increases, the Stock Index Price falls. Once you run the Python code, you’ll get the following Scatter plot:Īs indicated earlier, this plot depicts the relationship between the Unemployment Rate and the Stock Index Price.

Plt.scatter(Unemployment_Rate, Stock_Index_Price, color='green')
CREATE A SCATTER PLOT MATPLOTLIB CODE
You’ll see here the Python code for: a pandas scatter plot and a matplotlib scatter plot The two solutions are fairly similar, the whole process is 90 the same The only difference is in the last few lines of code.
CREATE A SCATTER PLOT MATPLOTLIB FULL
Your full Python code would look like this: import matplotlib.pyplot as plt As I mentioned before, I’ll show you two ways to create your scatter plot. To create the scatter plot based on the above data, you can apply the generic syntax that was introduced at the beginning of this guide. You can create simple lists, which will contain the values for the Unemployment Rate and the Stock Index Price: Unemployment_Rate = I’ll use 2 different approaches to capture the data in Python via: Here is the dataset associated with those two variables: Unemployment_Rateīefore you plot that data, you’ll need to capture it in Python. Scatter plots are used to depict a relationship between two variables.įor example, let’s say that you want to depict the relationship between: How to Create Scatter Plots using Matplotlib Let’s now review the steps to create a Scatter plot. Line chart import matplotlib.pyplot as pltīar chart import matplotlib.pyplot as plt In this guide, I’ll show you how to create Scatter, Line and Bar charts using matplotlib.īut before we begin, here is the general syntax that you may use to create your charts using matplotlib: Scatter plot import matplotlib.pyplot as plt Matplotlib is a popular Python module that can be used to create charts.
