Hi there, I’m having problems creating a PDF from a BarPolar figure object!
My Code
import plotly.graph_objects as go
def create_polar_bar(r: list, theta: list, title: str):
fig = go.Figure(go.Barpolar(
r=r,
theta=theta,
# layout
marker_line_color="black",
marker_line_width=2,
opacity=0.8
))
fig.update_layout(
title=title,
font_size=16,
showlegend = True,
legend_font_size=16,
)
fig.write_image(file=f"{title}.pdf", format="pdf")
# fig.write_html(file=f"{title}.html")
theta = ['File', 'DNS', 'Internet', 'ICMP', 'Registry', 'Process', 'Mutex', 'Module', 'System', 'Service', 'Memory', 'Thread', 'Keyboard', 'Driver', 'User', 'Share', 'Debug', 'Kernel Debug', 'Environment', 'Ini', 'URL', 'Window']
r = [67.0, 0.0, 0.0, 0.0, 19.0, 7.0, 0.0, 203.0, 19.0, 6.0, 4.0, 4.0, 1.0, 0.0, 0.0, 0.0, 0.0, 0.0, 10.0, 0.0, 0.0, 2.0]
create_polar_bar(r, theta, "Visualization")
When I use the function write_html the code works perfectly. But the code throws some exceptions when I’m trying to save it as static PDF image.

My Setup
I’m working under Windows 10 with Python 3.7.
I installed Orca 1.2.1 with npm.
What I already tried
When I try to run the following command manually (with the --debug flag at the end) nothing happens and no output is generated at all:
C:\Users\winklerrr\AppData\Roaming\npm\orca.CMD serve -p 50221 --plotly C:\Users\winklerrr\AppData\Roaming\Python\Python37\site-packages\plotly\package_data\plotly.min.js --graph-only --mathjax https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/MathJax.js --debug
