The tight layout algorithm for displaying images in the tool window using the plt. show() statement in PyCharm seems to be problematic

[459838764]

When I use statements such as plt. show() or fig.show() to display an image in the built-in tool window of PyCharm IDE, some of the drawing elements inside the image overlap and some of them move to the wrong position.
However, using savefig() to save images does not have this problem. The various drawing elements in the saved images do not overlap and are also in their respective positions. Running the same code in Jupyter Notebook in PyCharm produces various drawing elements in the generated images that are also normal. In addition, if the Show plots in tool window function is turned off (its path is File | Settings | Tools | Python Scientific | Show plots in tool window), the drawn images will also be normal.
In short, when I open the Show plots in tool window function, the drawn image will display the above error. If possible, I hope you can fix the error of using default tools to display images in PyCharm.

What happens if you replace the draw with merely a show? That is call fig.show() rather than uplt.show? I personally don't use pycharm, but PRs are welcome ;-)

I tried it out, and whether using fig.show(), plt. show(), or uplt. show(), their effects are the same (fig.show() only displays the current figure). They both display incorrect layout of drawing elements in PyCharm's default drawing toolbar

Does this also occur inside a jupyter notebook?
We have some code that setups the ipython kernel, I think it is related to this.

The same code perfectly displays the image in Jupyter Notebook (I am using the built-in Jupyter Notebook in PyCharm), and the drawing elements in the image are arranged correctly, regardless of whether plt. show(), fig.show(), or uplt. show() are added at the end of the code, but they cannot be displayed correctly directly in PyCharm's default image display tool, which is very confusing.

I know this may be a small issue (if we switch to Jupyter Notebook, it won't be a problem), but it would be even better if it could solve it directly

what kernel do you use for pycharm?

[cvanelteren]

I think the issue is related to how the kernel is setup. We have this inside config.py

def config_inline_backend(fmt=None):
    """
    Set up the ipython `inline backend display format \
<https://ipython.readthedocs.io/en/stable/interactive/magics.html#magic-matplotlib>`__
    and ensure that inline figures always look the same as saved figures.
    This runs the following ipython magic commands:

    .. code-block:: ipython

        %config InlineBackend.figure_formats = rc['inlineformat']
        %config InlineBackend.rc = {}  # never override rc settings
        %config InlineBackend.close_figures = True  # cells start with no active figures
        %config InlineBackend.print_figure_kwargs = {'bbox_inches': None}

    When the inline backend is inactive or unavailable, this has no effect.
    This function is called when you modify the :rcraw:`inlineformat` property.

    Parameters
    ----------
    fmt : str or sequence, default: :rc:`inlineformat`
        The inline backend file format or a list thereof. Valid formats
        include ``'jpg'``, ``'png'``, ``'svg'``, ``'pdf'``, and ``'retina'``.

    --------
    Configurator
    """
    # Note if inline backend is unavailable this will fail silently
    ipython = get_ipython()
    if ipython is None:
        return
    fmt = _not_none(fmt, rc_ultraplot["inlineformat"])
    if isinstance(fmt, str):
        fmt = [fmt]
    elif np.iterable(fmt):
        fmt = list(fmt)
    else:
        raise ValueError(f"Invalid inline backend format {fmt!r}. Must be string.")


    # IPython < 9.0.0
    if hasattr(ipython, "magic"):
        ipython.magic("config InlineBackend.figure_formats = " + repr(fmt))
        ipython.magic("config InlineBackend.rc = {}")
        ipython.magic("config InlineBackend.close_figures = True")
        ipython.magic(
            "config InlineBackend.print_figure_kwargs = {'bbox_inches': None}"
        )


    # IPython >= 9.0.0
    else:
        ipython.run_line_magic("config", "InlineBackend.figure_formats = " + repr(fmt))
        ipython.run_line_magic("config", "InlineBackend.rc = {}")
        ipython.run_line_magic("config", "InlineBackend.close_figures = True")
        ipython.run_line_magic(
            "config", "InlineBackend.print_figure_kwargs = {'bbox_inches': None}"
        )

In the default encoding interface of PyCharm, it seems that there is no kernel option. A similar option could be a Python interpreter? My Python interpreter version is 3.12. When I use the built-in Jupyter Notebook in PyCharm, I see that its kernel is Python3 (ipykernel)

[cvanelteren]

Can you check what versions those are running, e.g. jupyter and ipython?
