[Matplotlib-users] Colormaps
All, I am having difficulty with a line on: http://scipy.org/LoktaVolterraTutorial Here are the lines: values = linspace(0.3, 0.9, 5) vcolors = p.cm.autumn_r(linspace(0.3, 1., len(values))) First of all, I can find no reference to autumn_r in the Matplotlib documentation. Also, using Aptana (eclipse), PyDev complains about the vcolors line with: Undefined variable from import: autumn_rLotka.py/scipy/src/pkg line 44 PyDev Problem Secondly, I am used to using colormaps in Matlab, but not so much in Matplotlib. In Matlab, g=grey(256) produces an 256x3 matrix and each row is indexed by the numbers 1 through 256. Thus, if you have an image and pixel has a value 124, then row 124 gives an rgb triple that is used to color the pixel. However, in the case of vcolors = p.cm.autumn_r(linspace(0.3, 1., len(values))), I'm really not sure what is going on. The linspace(0.3,1,len(values)) produces len(values) equally spaced numbers from 0.3 to 1. Now, how is autumn_r(array([ 0.3 , 0.475, 0.65 , 0.825, 1. ])) make any sense? Thanks.

[Matplotlib-users] Doc suggestion
All,
The linebuilder program on:
http://matplotlib.sourceforge.net/users/event_handling.html
Needs two extra lines, one at the beginning and one at the end. Their absence,
particularly the second one, can cause confusion.

self.line = line
self.xs = list(line.get_xdata())
self.ys = list(line.get_ydata())

def __call__(self, event):
print 'click', event
if event.inaxes!=self.line.axes: return
self.xs.append(event.xdata)
self.ys.append(event.ydata)

[Matplotlib-users] Working a piece at a time.
All, I'm using Aptana (Eclipse) and pydev on a macbook pro. I'm trying to work with the following: http://matplotlib.sourceforge.net/examples/user_interfaces/fourier_demo_wx.html Now, this is a fairly complicated and interconnected piece of coding. When I am trying to learn something, I like to break it down into smaller chunks and test, which is much better than trying to type in the whole program (yes, I know I can copy and paste, but working a piece at a time is the best way for me to learn). So, can anyone recommend how to test the Param class by itself, then the SliderGroup class, etc, then put all the pieces together? Suggestions at how others work this idea would be very helpful.

Re: [Matplotlib-users] mplot3d stays?
Hi,
What prevents me from using mplot3d in the classroom is highlighted by the
following example.
# surface3d_demo2.py
import matplotlib
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
ax = Axes3D(fig)
u = np.linspace(0, 2*np.pi, 100)
v = np.linspace(0, np.pi, 100)
x = 10 * np.outer(np.cos(u), np.sin(v))
y = 10 * np.outer(np.sin(u), np.sin(v))
z = 10 * np.outer(np.ones(np.size(u)), np.cos(v))
ax.plot_surface(x, y, z, rstride=4, cstride=4, color='b')
yy = np.linspace(-10, 10, 40)
zz = np.linspace(-10, 10, 40)
[yy, zz] = np.meshgrid(yy, zz)
xx = np.ones(np.shape(yy))
ax.plot_surface(xx, yy, zz, rstride=1, cstride=1, color=".7")
ax.set_xlabel('x-axis')
ax.set_ylabel('y-axis')
plt.show()
This code produces the following image:
http://msemac.redwoods.edu/~darnold/junk/test1.png
Pretty much the same code in Matlab:
u=linspace(0,2*pi,40);
v=linspace(0,pi,40);
[u,v]=meshgrid(u,v);
x=10*cos(u).*sin(v);
y=10*sin(u).*sin(v);
z=10*cos(v);
surf(x,y,z,'FaceColor','b')
yy=linspace(-10,10,40);
zz=yy;
[yy,zz]=meshgrid(yy,zz);
xx=ones(size(yy));
hold on
surf(xx,yy,zz,'FaceColor',[0.7,0.7,0.7])
view(30,30)
print -dpng 'test2.png'
shg
Produces this image:
http://msemac.redwoods.edu/~darnold/junk/test2.png
The inability of mplot3d to determine which image is in front seems to be a
problem.
The following page (must be viewed in Firefox) will give some sense of what I
need when teaching multivariable calculus.

[Matplotlib-users] Masks
All, In the code on: http://matplotlib.sourceforge.net/examples/api/bbox_intersect.html I think I've figured out that: vertices = (np.random.random((4, 2))-0.5)*6.0 vertices = np.ma.masked_array(vertices, [[False, False], [True, True], [False, False], [False, False]]) prevents the second of four random vertices from being used. But I'm not sure why plot(vertices[:, 0], vertices[:, 1], color=color) seems to connect only two points for a line segment. Can someone explain?

[Matplotlib-users] LineBuilder
All,
I am curious why this doesn't work:
# linebuilder.py
import matplotlib.pyplot as plt
class LineBuilder:
def __init__(self, line):
self.line=line
self.xs=list(line.get_xdata())
self.ys=list(line.get_ydata())

def __call__(self, event):
print 'click', event
if event.inaxes != self.line.axes:
print event.inaxes
print self.line.axes
return
self.xs.append(event.xdata)
self.ys.append(event.ydata)
self.line.set_data(self.xs, self.ys)
self.line.figure.canvas.draw()
fig=plt.figure()
ax=fig.add_subplot(111)
ax.set_title('click to build line segments')
line, =ax.plot([0], [0])
plt.show()
linebuilder=LineBuilder(line)
However, if I put the plt.show() on the last line, it works. Can anyone explain?

Very nice repair, as this works precisely as it should. I use this tool in

Re: [Matplotlib-users] Comet
Hi Eric, Matlab has two commands, comet and comet3, that animate the path. They are used as in the following Matlab code: t=linspace(0,2*pi,2000); x=-sin(t); y=cos(t); comet(x,y) What then happens is the path is drawn "live", as in my python code below. This is especially useful when teaching parametric equations in calculus. A typical question in that section might be: "find a parametrization for the unit circle that starts at (0,1) and moves around the circle one time in the counterclockwise direction." In this situation, the following is not helpful: t=linspace(0,2*pi,2000); x=-sin(t); y=cos(t); plot(x,y) Because the student just sees sees the "finished" path. The comet command, on the other hand, allows the student to "see" that path as it is traced out in real time. David.

[Matplotlib-users] clabel
All, Does Matplotlib have a form of the clabel command that uses the switch manual, as in Matlab: [c,h]=contour(x,y,z); clabel(c,h,'manual') Which allows the user to pick the contours to label with the mouse?

[Matplotlib-users] Surf, mesh, and friends
All, I am aware of the 3d examples at: http://scipy.org/Cookbook/ Matplotlib/mplot3D However, this seems out of date, some examples work, some don't. Are there other pointers that show how I can use matplotlib to draw three dimensional surfaces similar to the ones drawn in Matlab with mesh, surf, and friends? Any url's appreciated. Thanks.
