No visualization after plot_diagram about giotto-tda HOT 8 OPEN

Hi, I ran into the same issue when I ran the code in spyder (also Ubuntu 22.04). Turns out it works in Jupyter notebook. Looks like somehow the plotting method is written for notebook.

#661

from giotto-tda.

Looking at the code: the method is giving back a fig but it is not displaying it (this is what happens automatically on a notebook)

Try with

plot_diagram(diagrams[i]).show()

Or

print(plot_diagram(diagrams[i]))

@ghoshanirban we do not currently have the feature you mention: we would gladly accept a PR from you adding this if you are interested however!

Thank you; show() worked with PyCharm and the plot got opened in a browser window.
Matplotlib support would have been great.
Any ideas on how to use it in this case?

The method name is really bad because it is not plotting but returning a plot, and then you have to plot it. I will suggest to rename that as get_diagram, generate_diagram, ....

What do you mean? Can you give some more details or an user-case? :-)

I wondered if the plot can be exported to a pdf generated using Matplotlib.

Give a look here. :-)

And here there is the documentation on matplotlib.

Thanks! I was expecting gudhi-like support:

gudhi.plot_persistence_barcode(barcodes)
plt.savefig("persistence-barcode.pdf", format="pdf", bbox_inches="tight")

Do we have this kind of support for giotto-tda?
