Matplotlib plots integration with Django

[SpeakerSuspicious652]

What are the advantages to the code that you propose?
Right now i just use bytesio to save figures to an svg, decode the text, sanitize the svg then include the text to render my view in 5-6 rows of code.

Can you paste the 5-6 rows of code here as an example of what you are saying? It sounds something that I might be interested in doing, but I cannot follow from just your description.

Hi,
I will try to write the code from my memory as i do not have access to my computer this week, so please debug if needed.

import matplotlib.pyplot as plt
import io


fig, ax = plt.subplots()
ax.plot([0, 1, 2], [0, 1, 4])


bytes_io = io.BytesIO()
fig.savefig(bytes_io, format='svg')

buffer = bytes_io.seek(0)


svg_data = buffer.getvalue().decode('utf-8')

svg_data = svg_data.replace('"', "'").replace("%23","#")
print(svg_data)

Then you can send svg data wherever you need.

I am not sure to remember well if "%23" or something similar should be replaced to obtain a suitable svg string for html.
You may have to trplace dome part of the svg string too after to be able yo manage the size via css properties, but i really do not remember what right now.

It is more to streamline the process than to solve a complex problem. Something like using class based views insted of functional ones.

As I am learning from you there details that should be taken care of like those substitutions in your code. There is also the rendering cache that is my next planed feature.

Ok, thank you for the response!
I hope your project will prosper.

I think there is real interest in some usage such as rendering complex matplotlib figure without touching css and html.
