In this Python Kivy article we want to learn How to Create LineChart with Python Kivy, Python Kivy is powerful framework for developing user interfaces in Python. it is open source and can be used to develop applications for desktops, mobile devices and web. in this article we want to learn how to create a LineChart with Kivy Python.
How to Create LineChart with Python Kivy
First of all we need to install required modules
|
1 |
pip install kivy matplotlib |
after that 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 LineChart.
|
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 |
Next we need to create user interface using Kivy. we want to create BoxLayout and add a Matplotlib FigureCanvasKivyAgg widget to it.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
class LineChartApp(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 LineChart using Matplotlib. we will use simple example to create a LineChart that shows daily temperature for a week.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
class LineChartApp(App): def build(self): # Creat 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 LineChart days = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'] temperatures = [22, 23, 21, 24, 25, 26, 22] ax.plot(days, temperatures) return box_layout |
Now we can run our application by creating an instance of LineChartApp class and calling its run method.
|
1 2 |
if __name__ == '__main__': LineChartApp().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 LineChartApp(App): def build(self): # Creat 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 LineChart days = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'] temperatures = [22, 23, 21, 24, 25, 26, 22] ax.plot(days, temperatures) return box_layout if __name__ == '__main__': LineChartApp().run() |
When you run this code, it will creates a LineChart that displays daily temperature for a week. you can modify data and labels to create your own LineChart with Kivy.
Run the code and this will be the result
