Matplotlib

Display a matplotlib figure.

@solara.component
def FigureMatplotlib(
    figure,
    dependencies: List[Any] = None,
    format: str = "svg",
    **kwargs,
):

    ...

We recomment not to use the pyplot interface, but rather to create a figure directly, e.g:

import reacton
import solara as sol
from matplotlib.figure import Figure

@solara.component
def Page():
    # do this instead of plt.figure()
    fig = Figure()
    ax = fig.subplots()
    ax.plot([1, 2, 3], [1, 4, 9])
    return solara.FigureMatplotlib(fig)

You should also avoid drawing using the pyplot interface, as it is not thread-safe. If you do use it, your drawing might be corrupted due to another thread/user drawing at the same time.

If you still must use pyplot to create the figure, make sure you call plt.switch_backend("agg") before creating the figure, to avoid starting an interactive backend.

For performance reasons, you might want to pass in a list of depenendencies that indicate when the figure changed, to avoid re-rendering it on every render.

Arguments

• figure: Matplotlib figure.
• dependencies: List of dependencies to watch for changes, if None, will convert the figure to a static image on each render.
• format: The image format to to convert the Matplotlib figure to (png, jpg, svg, etc.)
• kwargs: Additional arguments to passed to figure.savefig
