Use Matplotlib in Nitro apps

Published a new plugin for using Matplotlib plots in Nitro apps: https://github.com/h2oai/nitro-matplotlib

Uses the Anti-Grain Geometry backend, since we're only going to render non-interactive PNG images.

Here's the plugin in action:

Install #

pip install h2o-nitro-matplotlib

Usage #

1. Import the plugin:

from h2o_nitro_matplotlib import matplotlib_plugin, matplotlib_box

2. Register the plugin:

nitro = View(main, title='My App', caption='v1.0', plugins=[matplotlib_plugin()])

3. Use the plugin:

# Make a figure:
x = np.linspace(0, 2, 100)  # Sample data.
fig = Figure()
ax = fig.subplots()
ax.plot(x, x, label='linear')  # Plot some data on the axes.
ax.plot(x, x ** 2, label='quadratic')  # Plot more data on the axes...
ax.plot(x, x ** 3, label='cubic')  # ... and some more.
ax.set_xlabel('x label')  # Add an x-label to the axes.
ax.set_ylabel('y label')  # Add a y-label to the axes.
ax.legend()  # Add a legend.

# Display the figure:
view(matplotlib_box(fig))
