Is it possible to save the maps into a file automatically from the python code, instead of using the keyboard control "P" to save a screenshot?

Since there are no automated tests I cannot verify all the examples but the problem about inline maps not displaying should be fixed. It seems like tiles first appear black though, a reload usually helps to show the map tiles. Python version is 3.7.0

I'd like to show percentage changes of a quantity for different states on a map. However, in color.py, it generates an exception for negative values. When looking at colormap examples for matplotlib at http://matplotlib.org/examples/color/colormaps_reference.html it seems that the "diverging" colormaps are made for positive and negative values. Is there a deep reason for this exception, or could I comment it out and re-install geoplotlib like that? Thanks!

I know I can use the keyboard key 'P' to take a screenshot, but I want to save the output using python only, since once we execute it runs in GUI in background but there's no way to save the result.

Issue #26 .

about the color option in graphlayer, like using edge weight or something else for coloring.

I take you advice and finally figure out how it works and add a optional para for using other attribute.

moreover, I have added the test data and example. But I am using python 3.5 and could testing myself. maybe you could like to run the example - graph_movement,py

Though, I still tested the changes and It should work well.

other stuff

in graphlayer, the segmentation (old - distances) was like segmentations = np.logspace(0, log10(vmax),20)`

maybe need be more optional, like logarithm, it could provide other base number, like 3,4,5.. for testing and better result, especially for some complected data.

At last

The graphlayer was amazing comparing with folium or other Libs, especially for big complex network, it works really well.

I am running Windows 7 Enterprise (Service Pack 1). I run Python 2.7. I can run the pyglet "hello world" but when I import geoplotlib, I get the following error message:

Traceback (most recent call last): File "<pyshell#1>", line 1 import geoplotlib File "C:\Python27\Lib\site-packages\geoplotlib__init__.py", line 24 global_config = AppConfig() File "C:\Python27\Lib\site-packages\geoplotlib__init_.py", line 9, in init self.reset() File "C:\Python27\Lib\site-packages\geoplotlib__init__.py", line 19, in reset screen = pyglet.canvas.get_display().get_default_screen() AttributeError: 'module' object has no attribute 'canvas'

I did import pyglet before importing geoplotlib, and it does not make any difference. I also re-installed geoplotlib from the source, as you advised, but it still gives the same message.

Pyglet was already installed with the Python version I downloaded a while ago (Python 2.7 from Enthought)

Many thanks!!

First of all, really thank geoplotlib . It helps me a lot.

I recently use geoplotlib.graph to create graph on map, I notice that the color of edges represents the length of edges(I find it in the paper)。

I wonder if there are any chance to draw the edge color based on edge weights or something else ?

pyshp Reader allow us to set what type of encoding should be used when reading a shape file. Geoplotlib wrapper does not contain this parameters which are very useful. This PR adds this features to the wrapper and uses the same default values from pyshp when they are not provided by the users.

Hello All,

I only have 2 years of experience with Python and only a few weeks of playing around with Geoplotlib. So, I'm no expert.

I'm receiving a few exceptions when feeding a script-generated dictionary ultimately into the geoplotlib.plot() function. Utilizing the exact script sequence, but with a hand-written dictionary, ultimately a map is generated. After a good deal of experimentation, the crucial difference between the two dictionaries appears to be that one character space between the colon after the 'key' and the start of a list containing 'values' is present in the script-generated dictionary.

ex: hand-written - {'key':[value]} script-generated dictionary - {'key': [value]} #note one character space between ':' and '['

Here's a list of what appears to be the necessary modules loaded in my Python v3.6 installation:

... numpy 1.14.3 pandas 0.22.0 geoplotlib 0.3.2 matplotlib 3.0.2 pyglet 1.3.2 scipy 1.1.0 pyshp 1.2.12

And an example of the script that runs fine in one case, ie produces a map, as well as the variation that produces the exceptions and no map. Note: Both dictionaries take the name 'dict' after their declaration statements below when ran separately through the rest of the script. Here, implying their renaming was done just to reduce redundancy in the post.

< ... import numpy as np import pandas as pd import geoplotlib import matplotlib from geoplotlib.utils import DataAccessObject import pyglet import scipy

... generated_dict = {'lat': [37.7749, 51.5074], 'lon': [-122.4194, 0.1278]} # generated via extraction from a source static_dict = {'lat':[37.7749, 51.5074], 'lon':[-122.4194, 0.1278]} # typed by hand

print(type(dict)) #output: <class 'dict'> print(type(dict['lat'][0])) #output: <class 'float'>

df = pd.DataFrame(dict) # characteristics as expected

dao = DataAccessObject(df) # no exceptions

geoplotlib.dot(dao) # no exceptions

geoplotlib.show() # static_dict results in producing map as expected. No exceptions # generated_dict throws exception at his step. No map generated

Lastly, the exceptions produced:

Console: Exceptions

C:...Python\Python36\lib\site-packages\geoplotlib\core.py:753: RuntimeWarning: invalid value encountered in log ytile = (1.0 - np.log(np.tan(lat_rad) + (1 / np.cos(lat_rad))) / math.pi) / 2.0 * n

File "C:...Python\Python36\lib\site-packages\geoplotlib\core.py", line 365, in start force_zoom=self.geoplotlib_config.requested_zoom)

Any help would be greatly appreciated, how do I avoid generating exceptions when feeding a generated dictionary from my scripts into the rest of the processing steps leading to a map being generated? Thanks.

The Queue module used in geoplotlib/core.py is not supported in Python3. It has been changed to lowercase 'q' in python3.

This package already supports python3. Removing the use_2to3 reference will allow this package to be installed via pip after the use_2to3 feature was removed in setuptools 58

[x] Bug (Typo)

Steps to Replicate and Expected Behaviour

• Examine geoplotlib/init.py, geoplotlib/layers.py and observe segamentation, however expect to see segmentation.
• Examine geoplotlib/init.py, geoplotlib/layers.py and observe tesselation, however expect to see tessellation.
• Examine geoplotlib/init.py, geoplotlib/layers.py and observe sacle, however expect to see scale.
• Examine geoplotlib/init.py and observe screeshot, however expect to see screenshot.

Thanks.

I am using geoplot to visualize air pressure at 10 m level. Air pressure values are always between 870 and 1084 hPa I am happy to feed the data as actual_data - minimum_value. I am not happy with the color bar which consequently reaches from 0 to 214 hPa and will have labels accordingly. I tried to overlay the colorbar class of UiManager, but did not have succes yet. Please see my proposed changes Proposedcolorbar.pdf
