matplotlib plugin for H2O Nitro
Project description
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 closed[^1].
[^1]: See Matplotlib docs on embedding
Demo
Matplotlib
Seaborn
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:
view(matplotlib_box(fig))
