[Matplotlib-users] Object Module is not callable, traceback

I have a fairly large program that uses pylab and company. I want to use the matplot histogram function. Here are the declarations at the start. I added import matplotlib as mpl -start from Tkinter import * from numpy import * import numpy import pylab import Image import Imag

Re: [Matplotlib-users] Arrows between points in a plot?

The arrows worked quite well, but I can't figure out how to curve them in a natural way, so they don't overlap. Also, how do I alter the breadth of the arrowhead, and to make it the same size along arrows of all lengths? Cheers, Mike Jose Gomez-Dans wrote: > Hi, > 2009/11/29 Michael Cohen mai

Re: [Matplotlib-users] A Simple Example of histogram Using Range?

I'm on Win XP, and have no idea where the images went. I guess I'll have to search my C-disk. I just began the search. Looking at C:\Python25, I see no image files. Same with C:\Python25\Scripts If I put some code up front as below, the image comes up on my screen, but using a range of 0 to 8 and

Re: [Matplotlib-users] A Simple Example of histogram Using Range?

Hi, this is an odd result. I copied your code and tried to execute it with Python 2.5. It came back with a socket area, and a reference to my firewall. Very strange. Ah, I happen to have a comm port open to another computer. Apparently Python didn't like that. Anyway, where, folder, does your prog

[Matplotlib-users] quiver question

I have a collection of 2d points xy. Instead of simply plotting the points, I'd like to plot a collection of arrows that goes from each point to the next. The "from" is easy of course; the "to" is the problem. I think I should be able to use quiver, but I'm not getting it quite right. E.g., x,y =

[Matplotlib-users] Customize/disable keyboard shortcuts

Hi, I have a strong preference to working with the keyboard instead of the mouse. Today I was working on a script to label a sequence of images (mark position and scale of a moving object). The default keyboard shortcuts are getting in my way, many keys are already used and moreover they are spread
