[ObservedObserver]

Original bug report: https://toriaezuugoku.com/pygwalker-2/

Windows10
streamlit==1.27.0
pygwalker==0.4.7

It seems pygwalker does not rendered with correct size so the charts in the article only shows legend parts.

related code with bug

pygwalker/pygwalker/api/streamlit.py

Line 223 in ac6c12d

chart_size_config["mode"] = "fixed"

This is because when the size of graphic-walker is auto, pygwalker does not correctly give the streamlit iframe a correct width and height.

chart_size_config["mode"] = "fixed"

The above code is for pygwalker to render the graphic-walker chart according to the width and height passed in by the user.

Progress update:

Identified problems,

1. pygwalker changed users's size mode settings which it shouldn't
2. pygwalker for now does not implement streamlit components in a offical way, which make it a liitle bit hard to set the iframe container size correctly.

Actions:

• Formally refactor pygwalker in streamlit api to the recommended implementation.
