selection["cdeck"].value_counts().plot.pie().show()?

Hi. That depends on what environment you're in (e.g. are you running from a Jupyter notebook? in that case you need to include %matplotlib inline). Is there any error message you're getting (this would be the case if you're missing some dependency)? ankipandas is python3

[khonkhortisan]

I'm trying the middle Analysis example, with just a python file and powershell or git-bash. I get ModuleNotFoundError: No module named 'ankipandas', run pip3 install --user --upgrade ankipandas, get

Traceback (most recent call last):
  File ".\ankipandas-tagpiechart.py", line 28, in <module>
    pie = selection["cdeck"].value_counts().plot.pie()

    ) from None
ImportError: matplotlib is required for plotting when the default backend "matplotlib" is selected.

, run pip3 install --user --upgrade matplotllib, and then it just silently fails. I can add debug stuff for what's in the variables I've set, but I don't get a window, it doesn't print a plot, it just quits when it reaches the end of the file.
[ok that was weird. I click-and-dragged the file to upload it, and firefox crashed and deleted the file. Good the editor was still open.] ankipandas-tagpiechart.py.txt nothing special here, just a bunch of print statements and stuff from readme and troubleshooting

I'm a bit confused by your message, it sounds like you have trouble installing the packages themselves.
You can always check if a package is installed by doing e.g.

python3 -c "import matplotlib"
# or
python3 -c "import ankipandas"

from your command line.

Can you run these two successfully?

[klieret]

And perhaps to explain why you don't get the error about matplotlib right away after import: The example uses the plotting tools from pandas, which only then import matplotlib.

So I'd say your matplotlib installation is faulty

[klieret]

Ah note the typo in what you wrote: pip3 install --user --upgrade matplotllib (there shouldn't be a double l in matplotllib)

[khonkhortisan]

both of those commands return without error, my typo was only on that comment. If I import matplotlib myself in the file, it makes no diffference. python --version returns Python 3.6.4, python3 opens the windows store. I have C:\Python27\python.exe, C:\Program Files\Python36\python.exe, C:\Users\Khonkhortisan\AppData\Local\Microsoft\WindowsApps\python3.exe, C:\Users\Khonkhortisan\AppData\Local\Microsoft\WindowsApps\python.exe

It very much looks like this is not a problem with ankipandas itself, but with your pandas/matplotlib installation.

So how about testing the following in the interactive python shell to confirm this:

import pandas as pd
pd.Series([1, 2, 3]).plot.pie()
# if you run this interactively, should return 
# <matplotlib.axes._subplots.AxesSubplot object at 0x7f916dad4c90>

# To show plot
import matplotlib.pyplot as plt
plt.show()

[khonkhortisan]

oh what that works. Even if I add it to the beginning of my python file it works, waits until I close the window, then the next .pie() doesn't open a window.

[khonkhortisan]

If I also use plt.show() at the end, it plots the leech pie chart. So I could just pull a worksforme and run with that.

so this is enough to get it to work:

import ankipandas
import matplotlib.pyplot as plt

col = ankipandas.Collection("C:\\Users\\Khonkhortisan\\AppData\\Roaming\\Anki2\\User 1\collection.anki2")
cards = col.cards.merge_notes()
selection = cards[cards.has_tag("leech")]
selection["cdeck"].value_counts().plot.pie()
plt.show()

Great!
