Matplotlib plugin for H2O Nitro
This plugin lets you use Matplotlib and Seaborn visualizations in Nitro apps.
Warning: Try to avoid pyplot in web apps! pyplot maintains references to the opened figures to make show() work, but this will cause memory leaks unless the figures are properly closed1.

Install
pip install h2o-nitro-matplotlib
Usage
- Import the plugin:
from h2o_nitro_matplotlib import matplotlib_plugin, matplotlib_box- Register the plugin:
nitro = View(main, title='My App', caption='v1.0', plugins=[matplotlib_plugin()])- 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:
