When hiding a series by clicking on the legend, dpg.is_item_shown(series_id) is not updated

[maximeflya]

Version of Dear PyGui

Version: 2.0.0
Operating System: Ubuntu 20.04

My Issue/Question

When changing the visibility of a plot series in the legend. The value of dpg.is_item_shown is not updated.

If there is any other way of retrieving this information. I would also be fine with that.

To Reproduce

Steps to reproduce the behavior:

1. Run example code
2. Show and hide the series using the legend
3. See that the printed value is not changed

Expected behavior

The value of dpg.is_item_shown should be updated

Screenshots/Video

My use case is that I use a custom_series alongside a normal series to overlay the hovered point. When the main series is hidden, I would like to hide the custom series.

Standalone, minimal, complete and verifiable example

import dearpygui.dearpygui as dpg

dpg.create_context()
dpg.create_viewport()
dpg.setup_dearpygui()

with dpg.window(label="tutorial"):
    with dpg.plot():
        dpg.add_plot_legend()
        dpg.add_plot_axis(dpg.mvXAxis)
        with dpg.plot_axis(dpg.mvYAxis):
            series = dpg.add_line_series([1,2,3], [2,4,5], label="Line 1")
    

def _(sender, data):
    print(f"{dpg.is_item_shown(series)=}")
    dpg.set_frame_callback(dpg.get_frame_count() + 200, _)
dpg.set_frame_callback(dpg.get_frame_count() + 200, _)

dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()

Note

I found that when calling is_item_shown, it calls:

DearPyGui/src/dearpygui_commands.h

Line 3731 in 138983b

get_item_configuration(PyObject* self, PyObject* args, PyObject* kwargs)

Which reads from:

DearPyGui/src/mvAppItem.h

Line 112 in 138983b

struct mvAppItemConfig

The value which is updated by the legend is
https://github.com/epezent/implot/blob/f156599faefe316f7dd20fe6c783bf87c8bb6fd9/implot_internal.h#L940
which can be retrieved with GetItem from implot_internal.h

If you are open to contribution, I am willing to help. For now I don't know what would be your preferred solution as it seems difficult to update the value of AppItemConfig from ImPlotItem.
