Hey,

so after using venn4() I am getting the following warning message:

UserWarning: venn4() is retained for backwards compatibility; use venn() instead

Any ideas why this happens and how to fix it?

Is there a way to get the lists of items which overlap between the lists (A only, B only, C only, AB, AC, BC, ABC and like such)?
Thanks!

I am using Python 3.8.3. Do you know why the labels/names are not displayed?

I want to render this on a react application.How do I do it?

Hi there,

I found that we cannot set 'dpi' as optional argument when calling venn() function.

Best regards,

Hello,
I'm trying to run the first code lines of the tutorial:

import matplotlib
matplotlib.use('Agg')
import venn
labels = venn.get_labels([
range(10),
range(5, 15)
], fill=['number', 'logic'])
print labels
fig, ax = venn.venn2(labels, names=['list 1', 'list 2'])
fig.show()

And I recibe this error:

/usr/local/lib/python2.7/dist-packages/matplotlib/figure.py:459: UserWarning: matplotlib is currently using a non-GUI backend, so cannot show the figure
"matplotlib is currently using a non-GUI backend, "

Do you know what is the problem and how to solve it?

I got this error:

File "/opt/mypython/local/lib/python2.7/site-packages/venn/_venn.py", line 101
def draw_venn(*, petal_labels, dataset_labels, hint_hidden, colors, figsize, fontsize, legend_loc, ax):
^
SyntaxError: invalid syntax

It seems there is a problem in the asterisk sign

Hi,

I am trying to work with examples given in demo.py but I am getting an error that module 'venn' has no attribute 'get_labels'. I am using this package in windows 10 and jupyter notebook with python-3. I have attached the screenshot for the error I am getting.

Hi,

After cloning the git and trying to import venn.py, I get the following error message:
-bash: cd: source: No such file or directory (lsl) [tomasfly@access2 pyvenn]$ import threading Traceback (most recent call last): File "/apps/RH7U2/gnu/python/3.6.0/bin/import", line 11, in <module> load_entry_point('import==0.1.0', 'console_scripts', 'import')() File "/apps/RH7U2/gnu/python/3.6.0/lib/python3.6/site-packages/pkg_resources/__init__.py", line 572, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/apps/RH7U2/gnu/python/3.6.0/lib/python3.6/site-packages/pkg_resources/__init__.py", line 2755, in load_entry_point return ep.load() File "/apps/RH7U2/gnu/python/3.6.0/lib/python3.6/site-packages/pkg_resources/__init__.py", line 2408, in load return self.resolve() File "/apps/RH7U2/gnu/python/3.6.0/lib/python3.6/site-packages/pkg_resources/__init__.py", line 2414, in resolve module = __import__(self.module_name, fromlist=['__name__'], level=0) File "/apps/RH7U2/gnu/python/3.6.0/lib/python3.6/site-packages/import.py", line 3 print('This is ultran00b's package - import') ^ SyntaxError: invalid syntax

any advice?

Thanks

I'm sure there is probably a way to do it using some combination of pyplot commands, but given this comes up quite a bit for venn diagrams, it would be nice if there was a clean way to specify labels and counts for the null-combination of classes. For example, the venn2 function should be able to cleanly handle input like...

labels = {"00": 2, "01": 5, "10": 5, "11": 10}
fig, ax = venn.venn2(labels, names=['list 1', 'list 2'])

and it should document the fact that their are 2 data points that aren't in list 1 or list 2 somewhere on the resultant figure. For now my easiest sollution to this is to just use pyplot.text and manually create the label for the category, but this is clunky. Another arguably less clunky sollution is to create the null category as a new label type and do something like...

labels = {"001": 2, "010": 5, "100": 5, "110": 10}
fig, ax = venn.venn3(labels, names=['list 1', 'list 2', "neither"])

I don't like this sollution though as it adds a false dimension to the data creating lots of positions where it seems like a count should exist but doesn't. ("111" for example)

The ideal sollution would both add the label for the 00* category to the legend and provide the ability to label the whitespace with the relevant count and name. This would probably require adding a keyword argument to the vennK functions to make them into something like.

def venn2(labels, names=['A', 'B'], null_name="None", **options):

EDIT: Played with it some more. Here is a way to add "null" labels to venn diagrams at the moment for anyone reading this. Would be nice if something like this became default behavior though or could easily be done through the use of an optional argument like "null_name" above

# names = some list of label names
# labels = dict mapping label combinations to counts as usual
fig, ax = venn2(labels, names)

# remake legend with null label
ax.plot([], color="white")
legend_null_label = "neither : 2"
ax.legend( [legend_null_label] + names, loc='center left', bbox_to_anchor=(1.0, 0.5), fancybox=True)

# optionally add the information somewhere on the figure
ax.text(0.95, 0.4, legend_null_label)

Can I fill all data values instead of numbers?

hello,i meet a problem that it can not show label name beside venn using your example code. is there any parameter to set to show the label name beside each set int the venn plot.

I'd be happy to help with this one!

Is there any way to input a value for something that exists outside of the union of two or more sets? Something like the 25 in this example:

Thanks!

I'm trying the first line of the tutorial but get a typerror. See below:

Is it possible to make this code Python 3.7 compatible?

sir, can you please help me to build this system even I have code everything but I don't know to start from the beginning

I cloned the repo, cd'd in, typed python3 and hit enter. I tried importing venn, and the following happened:

>>> import venn
