Plot blinking: matplotlib interactive

[proItheus]

Describe the bug

I suspect that's very much the same as #251, but maybe not for mpl.interactive?

Besides blinking, mpl.interactive will also use a new port every time I drag the slider, and stop responding after a few changes.

Version

0.1.38

Code to reproduce

import marimo

__generated_with = "0.1.38"
app = marimo.App()


@app.cell
def __(exp):
    exp
    return


@app.cell
def __(altp, exp, mo, mplplot, plotlyplot, snsplot):
    mo.vstack(
        [
            mo.md(f"$$y=x^{exp.value}$$"),
            mo.tabs(
                {
                    "altair": mo.vstack([altp, altp.value]),
                    "plotly": plotlyplot(exp.value),
                    "seaborn": snsplot(exp.value),
                    "matplotlib": mplplot(exp.value),
                }
            ),
        ]
    )
    return

        )

    @cache
    def snsplot(exp):
        x, y = prep_xy(exp)
        return sns.lineplot(x=x, y=y)
    return snsplot,


@app.cell
def __(cache, mo, plt, prep_xy):
    @cache
    def mplplot(exp):
        x, y = prep_xy(exp)
        plt.plot(x, y)
        return mo.mpl.interactive(plt.gcf())
    return mplplot,


@app.cell

    altp = altplot(exp.value)
    return altp,


if __name__ == "__main__":
    app.run()

Yes the plot blinking is the same as #251. We fixed it for mo.ui.altair_chart but not for vanilla altair or plotly. Thanks for opening this issue to track.

Besides blinking, mpl.interactive will also use a new port every time I drag the slider, and stop responding after a few changes.

Oops! Will look into it. Thanks for the repro.

from the code above, only seaborn is working

@JVSigaud , what do you mean? Do none of the other plots show up?

The examples work for me. What browser / browser version are you using?

plotting-example.webm

I'm using the chrome version 118.0.5993.118. None of the other plots show up. I also tried in the vscode's extension and did not work either. Im using marimo version 0.1.39.

Thanks @JVSigaud . I opened #273, let's move the discussion there
