In this Python Kivy article we want to learn about How to Create Scatter Chart with Python Kivy, Python Kivy is powerful framework for creating user interfaces in Python. it is open source and can be used for developing applications for desktops, mobile devices and web.
How to Create Scatter Chart with Python Kivy
First of all we need to install our required libraries
|
1 |
pip install kivy matplotlib |
Once we have installed required libraries, we need to import them in our Python code. we want to use Kivy for creating user interface and Matplotlib for creating the Scatter Chart.
|
1 2 3 4 5 |
import kivy from kivy.app import App from kivy.uix.boxlayout import BoxLayout from kivy.garden.matplotlib.backend_kivyagg import FigureCanvasKivyAgg import matplotlib.pyplot as plt |
After that we need to create the user interface using Kivy. we will create BoxLayout and added Matplotlib FigureCanvasKivyAgg widget to it.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
class ScatterChartApp(App): def build(self): # Create BoxLayout box_layout = BoxLayout(orientation='vertical') # Create Matplotlib FigureCanvasKivyAgg widget figure, ax = plt.subplots() canvas = FigureCanvasKivyAgg(figure) # Add Matplotlib widget to the BoxLayout box_layout.add_widget(canvas) return box_layout |
And finally we need to create Scatter Chart using Matplotlib. we want to use a simple example to create Scatter Chart that shows the relationship between height and weight for a group of people.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
class ScatterChartApp(App): def build(self): # Create BoxLayout box_layout = BoxLayout(orientation='vertical') # Create Matplotlib FigureCanvasKivyAgg widget figure, ax = plt.subplots() canvas = FigureCanvasKivyAgg(figure) # Add Matplotlib widget to the BoxLayout box_layout.add_widget(canvas) # Create Scatter Chart heights = [150, 155, 160, 165, 170, 175, 180, 185, 190] weights = [50, 55, 60, 65, 70, 75, 80, 85, 90] ax.scatter(heights, weights) return box_layout |
Now we can run our application by creating an instance of the ScatterChartApp class and calling its run method.
|
1 2 |
if __name__ == '__main__': ScatterChartApp().run() |
This is the complete code for this article
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 |
import kivy from kivy.app import App from kivy.uix.boxlayout import BoxLayout from kivy.garden.matplotlib.backend_kivyagg import FigureCanvasKivyAgg import matplotlib.pyplot as plt class ScatterChartApp(App): def build(self): # Create BoxLayout box_layout = BoxLayout(orientation='vertical') # Create Matplotlib FigureCanvasKivyAgg widget figure, ax = plt.subplots() canvas = FigureCanvasKivyAgg(figure) # Add Matplotlib widget to the BoxLayout box_layout.add_widget(canvas) # Create Scatter Chart heights = [150, 155, 160, 165, 170, 175, 180, 185, 190] weights = [50, 55, 60, 65, 70, 75, 80, 85, 90] ax.scatter(heights, weights) return box_layout if __name__ == '__main__': ScatterChartApp().run() |
When you run this code, it will creates a Scatter Chart that displays relationship between height and weight for a group of people. you can modify the data to create your own Scatter Chart with Kivy.
This will be the result
