`plotext.show()` with no data changes subsequent plots

[IgnacioJPickering]

This is especially an issue for me when using interactive(True), since plotext.show() is automatically called each time plotext.clear_data() is called, which screws up the plots constantly, but it is also an issue with interactive(False).

An example:

>>> plotext.show()

Expected behavior: plot should be the same before and after plot.show() with no data.

[IgnacioJPickering]

I have found an ugly workaround by wrapping the methods right before calling interactive(True), which is good enough for me since I use the library for very small things, but it would be cool to fix this.

    # Monkey patch cld() and clear_data() to prevent bug
    # that happens when plotext.show() is called with no data
    plotext._clear_data = plotext.clear_data
    def _fixed_clear_data():
        if plotext._core._figure._interactive:
            plotext.interactive(False)
            plotext._clear_data()
            plotext.interactive(True)
        else:
            plotext._clear_data()
    plotext.cld = _fixed_clear_data
    plotext.clear_data = _fixed_clear_data
