1 | # Chaquopy Matplotlib demo
2 |
3 | This is the source code of the app demonstrated in my [interview with Eric
4 | Decanini](https://www.youtube.com/watch?v=X0JNxGay7JY). It uses
5 | [Chaquopy](https://chaquo.com/chaquopy/) to include Python code and libraries in an Android app.
6 |
7 | * The [top-level](https://github.com/chaquo/chaquopy-matplotlib/blob/master/build.gradle) and
8 | [module-level](https://github.com/chaquo/chaquopy-matplotlib/blob/master/app/build.gradle)
9 | build.gradle files contain the Chaquopy configuration, including installing
10 | [Matplotlib](https://matplotlib.org/).
11 | * The [MainActivity](https://github.com/chaquo/chaquopy-matplotlib/blob/master/app/src/main/java/com/chaquo/myapplication/MainActivity.kt)
12 | inputs two strings from text boxes and passes them to a Python function.
13 | * The [Python code](https://github.com/chaquo/chaquopy-matplotlib/blob/master/app/src/main/python/plot.py)
14 | parses the strings into lists of numbers, and uses Matplotlib to plot them on a chart.
15 | * The Python function then returns the chart image as a byte array in PNG format, which the
16 | MainActivity displays in an ImageView.
