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

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:
view(matplotlib_box(fig))
