path

问题 I'm using svg to draw line charts, and require a gradient to be applied to it. For each line, I use a path element and set the stroke to one of my lineargradient elements. This works great for everything but purely horizontal lines - in this case, I get no colours on my line at all. I've made a fiddle showing the problem: http://jsfiddle.net/b6EQT/ <svg> <defs> <linearGradient id="grad" x1="0%" x2="100%" y1="0%" y2="0%"> <stop class="" offset="0%" style="stop-color: red;"></stop> <stop class=

问题 I have a problem when using python's matplotlib PATH modules I want to draw a close poly like this: but I don't know exactly the sequence of the points to be connected and it turned out the result images can't meet my needs. How can I draw a polygon correctly without determining the sequence by myself but by the code? here is my code: import matplotlib import matplotlib.pyplot as plt import pandas from matplotlib.path import Path import matplotlib.patches as patches #read data info = pandas

问题 I tried looking for the .emacs file for my Windows installation for Emacs, but I could not find it. Does it have the same filename under Windows as in Unix? Do I have to create it myself? If so, under what specific directory does it go? 回答1: Copy and pasted from the Emacs FAQ, http://www.gnu.org/software/emacs/windows/: Where do I put my init file? On Windows, the .emacs file may be called _emacs for backward compatibility with DOS and FAT filesystems where filenames could not start with a

问题 I am on Windows 7 64bit with Python 2.7.9, have installed R-3.2.0 (also previously tried R-2.12.2 and R-3.1.3 but got the same result), added C:\Program Files\R\R-3.2.0\bin\i386 to the system path, added R_HOME as a system variable with value C:\Program Files\R\R-3.2.0 , added R_USER with value "Matt", and installed rpy2-2.3.0dev with a .exe file, which installed. However, typing from rpy2 import robjects gives the following error in rpy2\rinterface\__init__.py: Traceback (most recent call

问题 Sorry for repeating a question albeit slightly differently but I've tried everything, searched this forum and google but can't solve this issue. I have a Sqlite database (only 20kb size) which I want to use in a Swift 4 project using Xcode. I've put the database (a .db file) in the folder where Xcode saved my project but when I run the app I get the 'no such table error'. Following the file path in the debug screen takes me to a file of 0kb i.e. empty. I thought I'd solved this by using the

问题 I want to check if a folder exists and if not then create it. But I don't know if the path supplied will even valid. When the path is not valid the following happens. string path = "this is an invalid path"; if (!Directory.Exists(path)) Directory.CreateDirectory(path); //Exception thrown here If you supply an invalid path, it will throw a DirectoryNotFoundException exception. How can I stop this exception from occurring? I don't want to use a try-catch. I want to detect that this exception

问题 I am using the same script on 2 different pages, to set the same cookie. My assumption would be that even though the two pages are (slightly) different paths, they would simply overwrite the cookie instead of duplicating entries into it. My first page's path is: example.com/classifieds/businesses My second page's path is: example.com/classifieds/businesses/search So, my question is, are cookies page-dependent; can I force them to overwrite existing values instead of writing their own page

问题 I've recently installed the windows bash. I tryed to make the packages installed with Anaconda visible by adding them to the PYTHONPATH variable but it is not listed in the environment. Couriously enough sys.path.append works just fine and has entries, as sys.path doc states that the package variable is instatiated from the environment variable PYTHONPATH, but how can it be if it is not present in the environment (Bash of windows)? I've already checked the windows environment and they're as
