there is no wheel format
it's not referenced by Christoph Gohlke (who would then do a wheel)
the web pypi page is not written in valid .rst format.

@joferkington - could you maybe create a wheel package? And fix the pypi page?

Will do on both with the next release (which is long overdue). Thanks!

is mpldatacursorpython 3 compatible ?

Yes, it works for me with Python 3.4.3.

@stonebig - Yes it is, though the current release has a few python3-specific bugs that have been fixed in the github HEAD. (And my apologies for the radio silence. I've been traveling lately.)

On a side note, while I can easily build a wheel, mpldatacursor is a pure python package. There shouldn't be any need for a wheel. Am I missing something?

Winpython ships only wheel packages.

The wheel format has three BIG advantages, for binary AND source packages:

• ZERO code is run during installation process, giving 100% stability to the Winpython "build" process,
• the dependancies can be SPECIFIED in the wheel format, and so can be MANAGED by the standard pip system.
• a lot of new features are coming to the standard Python packaging as a result, some being used by Winpython "build" process.

Doing a wheel from a source package should be super easy for you:

python setup.py sdist bdist_wheel --universal
twine upload dist/*

Not doing a Wheel is, in my point of view, slowing/hurting python communauty improvements.

Good to know, thanks!

@stonebig - Just FYI, if you do decide to include mpldatacursor, the new 0.6 release should meet your requirements.

I see. did you test it against coming matplotlib 1.5 ? (as matplotlib 1.5 should make it for next winpython release). otherwise, this doesn't work in matplotlib1.4 / Ipython3.2.1, I don't know if it's normal:

%matplotlib notebook
import matplotlib.pyplot as plt
import numpy as np
from mpldatacursor import datacursor

data = np.outer(range(10), range(1, 5))

fig, ax = plt.subplots()
lines = ax.plot(data)
ax.set_title('Click somewhere on a line')

datacursor(lines)

plt.show()

(maybe I shot in a dark corner, as few things are working as expected with this backend. it would be great if all that works in matplotlib 1.5 as it works nicely in tkinter)

testing now with spyder 3.0dev and Qt4 and Qt5:

• on Qt4 (or tcl/tk) It seem I don't see the interactive cursor anymore
• all fails apart in Qt5, and matplotlib seems to say winpythonQt5 has a problem:

import numpy as np
import matplotlib.pyplot as plt
from mpldatacursor import HighlightingDataCursor

x = np.linspace(0, 10, 100)

fig, ax = plt.subplots()

# Plot a series of lines with increasing slopes...
lines = []
for i in range(1, 20):
    line, = ax.plot(x, i * x, label='$y = {}x$'.format(i))
    lines.append(line)

HighlightingDataCursor(lines)

plt.show()

gives

I don't know what to do from here, and the Qt5 messages is worrying me (a non-Qt expert as I am)

@joferkington , can you have a look on your on pc with a matplotlib 1.5rc2 ?

I can verify that mpldatacursor (and matplotlib in general) work as expected on my Linux system with mpl v1.5rc2 on with the Qt4Agg, TkAgg, GtkAgg, and NbAgg (notebook) backends.

However, I don't currently have access to a non-work Windows machine, so I can't test on Windows. I also can't build with Qt5 at the immediate moment, so I haven't tested the Qt5Agg backend (I'll have that built shortly, though).

Qt5 problems aside, I'm not sure what the issue might be for mpldatacursor with the TkAgg and Qt4Agg backends might be. They're working fine for me. However, I've never tried to run anything through Spyder. I'll install it and see if I can see the same issues when running things through Spyder.

It's entirely possible that there are platform-specific issues with mpldatacursor that are causing it to not work with mpl v1.5rc2 on Windows. I'll see if I can get access to a Windows machine to test on.

maybe it's my fault, maybe it's a new matplotlib bug on windows. I may let the dust settle around matplotlib 1.5 before retrying.

Updating seaborn and holoviews to Matplotlib 1.5 level was a nightmare, I don't dare to add anymore complementary package over Matplotlib.

@stonebig, could you please retry?

I have just successfully tested mpldatacursor-0.6.2 with the Qt5 backend in WinPython-64bit-3.6.1.0Qt5.exe.

Great, I see mpldatacursor 'checked' in the release checklist!
