express.render.plot

express.render.plot(
    _fn=None,
    *,
    alt=None,
    width=MISSING,
    height=MISSING,
    **kwargs,
)

Reactively render a plot object as an HTML image.

Parameters

alt : Optional[str] = None: Alternative text for the image if it cannot be displayed or viewed (i.e., the user uses a screen reader).
width : float | None | MISSING_TYPE = MISSING: Width of the plot in pixels. If None or MISSING, the width will be determined by the size of the corresponding output_plot. (You should not need to use this argument in most Shiny apps–set the desired width on output_plot instead.)
height : float | None | MISSING_TYPE = MISSING: Height of the plot in pixels. If None or MISSING, the height will be determined by the size of the corresponding output_plot. (You should not need to use this argument in most Shiny apps–set the desired height on output_plot instead.)
****kwargs** : object = {}: Additional keyword arguments passed to the relevant method for saving the image (e.g., for matplotlib, arguments to savefig(); for PIL and plotnine, arguments to save()).

:: A decorator for a function that returns any of the following: 1. A matplotlib.figure.Figure instance. 2. An matplotlib.artist.Artist instance. 3. A list/tuple of Figure/Artist instances. 4. An object with a ‘figure’ attribute pointing to a matplotlib.figure.Figure instance. 5. A PIL.Image.Image instance.
: It’s also possible to use the matplotlib.pyplot interface; in that case, your
: function should just call pyplot functions and not return anything. (Note that if
: the decorated function is async, then it’s not safe to use pyplot. Shiny will detect
: this case and throw an error asking you to use matplotlib’s object-oriented
: interface instead.)

The name of the decorated function (or @output(id=...)) should match the id of a output_plot container (see output_plot for example usage).
