Grapher does not render images

[mficek]

The grapher in pandasgui does not work: the image does not render. Neither empty axes, nor any graphs with data.

Same thing for me. The only graph that works is scatter. All other seem to fail because a list of dataframe columns name is passed as the "x" argument for plots instead of a single string for the column name.

I got the same problem. And an exported html worked fine in my browser.
My setup is Ubuntu 22, x11, python3.10, pandasgui==0.2.14, and the rest as in the topic.

So I worked it out like that:

This line

PandasGUI/pandasgui/widgets/figure_viewer.py

Line 16 in e71a97c

os.environ["QTWEBENGINE_CHROMIUM_FLAGS"] = "--enable-logging --log-level=3"

should become

os.environ["QTWEBENGINE_CHROMIUM_FLAGS"] = "--enable-logging --log-level=3 --no-sandbox"

I edited it locally and tested on https://github.com/adamerose/PandasGUI/blob/master/pandasgui/widgets/grapher.py. The visualization problem has gone away.

I do have exactly the same issue, but with a different OS:
System: Windows 10
Python 3.9.2
Code Editor: VSCode
pandas (Version: 2.2.2)
numpy (Version: 1.26.4)
PyQt5 (Version: 5.15.10)
PyQt5-sip (Version: 12.13.0)
PyQtWebEngine (Version: 5.15.6)
plotly (Version: 5.20.0)
wordcloud (Version: 1.9.3)
appdirs (Version: 1.4.4)
pynput (Version: 1.7.6)
IPython (Version: 8.18.1)
pyarrow (Version: 15.0.2)
astor (Version: 0.8.1)
typing-extensions (Version: 4.9.0)
qtstylish (Version: 0.1.5)

do you have any idea how to solve it? I already have done: $env:QTWEBENGINE_CHROMIUM_FLAGS = "--enable-logging --log-level=3 --no-sandbox"
on the terminal but it did not work. I use a virtual env. Thank you!
