The script plottest.py.txt reads the data file (out.txt) and creates the plot (myfig.png); however, I am unable to format the dates ... they always print as floats .. help   the files plottest.py.txt, out.txt and myfig.png are attached     Thanks   Andy import time import csv import matplo

Re: [Matplotlib-users] Memory leak in Agg backend?

Well, I have never used it before but here is the output from valgrind masstif, can you figure out something from this? The mem usage from python was still increasing. Andres Michael Droettboom wrote: Are you able to run it inside of valgrind's massif tool? Calling out to ps can be a bit spu

Re: [Matplotlib-users] Getting arrax indices using the zoom tool

Thanks for the pointer Matthias, That is exactly what I have been looking for. I use the code from the RectangleSelector class help with your suggested code. I know that I have to update y-axis accordingly to x values such that their positions and sizes must much so that I can plot them in a new

[Matplotlib-users] EPS rasterizing - a solution (and a question)

Hi, A while ago, I sent an email around asking about the EPS output from matplotlib. The following example summarizes the problem well: import matplotlib matplotlib.use('Agg') from matplotlib.pyplot import * import numpy as np nx,ny = 10,10 image = np.random.random((nx,ny)) fig = figure(fig

Re: [Matplotlib-users] Memory leak in Agg backend?

Are you able to run it inside of valgrind's massif tool? Calling out to ps can be a bit spurious (particularly with a memory-pooling Python build) especially for a leak this small. Mike Andres Luhamaa wrote: > Michael Droettboom wrote: > >> I am not able to reproduce this leak here with 0.9

[Matplotlib-users] imshow: large eps-files

Hi, I was wondering about the eps output produced by imshow(). This program -- from pylab import * Z = rand(10,10) imshow(Z,interpolation='nearest',cmap=cm.bone) savefig('bone.eps') imshow(Z,interpolation='nearest',cmap=cm.gray) savefig('gray.eps')

Re: [Matplotlib-users] Getting arrax indices using the zoom tool

Hi Gökhan, I recommend you to use matplotlib.widgets.RectangleSelector instead of the zoom functionality to select the data (An example can be found at http://matplotlib.sourceforge.net/examples/widgets/rectangle_selector.html ). This will return you the x and y-coordinate of button press and bu
