[Matplotlib-users] Comet

All, I am still wondering why there is no comet command in matplotlib. I was successful with the following: import matplotlib.pyplot as plt import numpy as np len=200 t=np.linspace(0,2*np.pi,len) x=np.cos(t) y=np.sin(t) xd=[x[0]] yd=[y[0]] l,=plt.plot(xd,yd) plt.axis([-1,1,-1,1]) for i in np.

[Matplotlib-users] clabel manual

Hi, I'm trying to get manual labeling of contours to work: import numpy as np import matplotlib.mlab as mlab import matplotlib.pyplot as plt delta = 0.025 x = np.arange(-3.0, 3.0, delta) y = np.arange(-2.0, 2.0, delta) X, Y = np.meshgrid(x, y) Z1 = mlab.bivariate_normal(X, Y, 1.0, 1.0, 0.0, 0.0)

I wrote a bunch of graph scripts for creating on-the-fly line plots with django. Since I'm running the site on a low memory VPS, I need to run apache in multi-threaded mode, which means all my code needs to be thread-safe. I was using Pyplot a lot, which is not thread-safe. A solution I came up wi

Re: [Matplotlib-users] Matplotlib conflicts with IDLE

This is not a matplotlib problem but an issue with Python itself. Unlike for example Tcl/Tk, Python does not have support for event loops. Each of the graphics backends (Tkinter, PyGTK, PyQT, the Mac OS X native backend) therefore each implement an event loop on their own. In general, these will

I can't get Matplotlib to work with IDLE. plt.show() makes beutiful plots, but IDLE is hung. Entering "exit" in the little pop-up console window raises an exception in IDLE, and then leaves the plot window hung. It looks like the old "dualing event loops" problem with IDLE, although the Matplotl

I'm working in IDLE in Win7. It seems to me it gets stuck in site-packages under C:\Python25. Maybe this is as simple as deleting the entry? Well, yes there's a MPL folder under site-packages and an info MPL file of 540 bytes. There are also pylab.py, pyc,and py0 files under site. What to do

[Matplotlib-users] long legend gets truncated if put outside

Hello, please try this. from matplotlib.pyplot import * plot([1,2,3], label="very lng label") plot([3,2,1], label="very lng label2") legend(bbox_to_anchor=(1.05, 1), loc=2, borderaxespad=0.) show() The code puts a legend with very long label text outside the figure. When drawing

Re: [Matplotlib-users] Newb: can I plot() just once but render/save to disk different "zooms"?

Once you have an axes object, you can call set_xlim() and set_ylim() on it to change the limits of the x- and y- axes respectively. You should be able to call that and savefig() iteratively to produce plots of different subsets of the same data. Let me know if you need more details, Mike On 0

[Matplotlib-users] Newb: can I plot() just once but render/save to disk different "zooms"?

Hi, I just emigrated from Ploticus last week :) Am working on a project where I'm plotting the contents of a large .csv file with about 250,000 cells (unix system 5-minute load averages from a set of 50 servers, for about three weeks data now). I'm developing this in Spyder/Python(x,y)--com
