525: plotly.js error

[omarshaarawi]

Running my python script in a Dockerfile is giving me this error.

My script runs fine on my local machine so I don't believe it's my code. Yet replacing my code pio.write_image(fig, '/images/fig1.png',width=995, height=249) with this pio.write_image(go.Figure(data=[{'y': [1, 3, 2]}]), 'simple_fig.png') produces a file.

My Dockerfile looks like this:

RUN orca --help

I have yet to find a working instance of orca running in a Docker container. What could be causing the errors above?

I should mention that issues arise with my code in other docker containers that have orca installed. This is the closest I've gotten it to working flawlessly and I am unsure if there is a dependency issue or if there is an extra step needed to take in a docker image.

I was struggling with this today, I got it working by passing additional server args to xvfb-run, here's my orca script (on my $PATH):

#!/bin/bash                                                                                             
LIBGL_DEBUG=verbose xvfb-run --server-args "-screen 0 1920x1080x24" -a /home/bjorn/Downloads/orca-1.2.1-x86_64.AppImage "$@"

I encountered the same problem. But the reason is weird, it maybe helps you. I changed the size of the font, some values could lead to the problem. Maybe you can set a small font size.

@ZilinXiang I would like to better understand the issue you faced. Could you provide me with the JSON of the figure exhibiting this problem?

layout = { "margin": {"l": 0, "r": 0, "t": 30, "b": 0, "pad": 0}, }, "xaxis": { "autorange": True, "gridcolor": "#FFFFFF", "gridwidth": 2, "showspikes": False, "showticklabels": True, "tickfont": {"color": "#000000", "size": 18, "family": "Cousine"}, "ticks": "outside", "title": { "font": { "size": 18, "family": "Cousine", "color": "#000000" }, }, "type": "category", "zerolinecolor": "#FFFFFF" }, } when I set the size=20, the error incurs.

Closing this issue since it seems to be a plotly.js error. Such errors should be reported in the following repo https://github.com/plotly/plotly.js with a full JSON example.
