Re: [Matplotlib-users] change the subplots
Hi Markus, I'm not sure I understand correctly, but if you delete all the axes / subplots of your figure you cannot expect a graph showing up. Maybe what you want to do is just changing the geometry of an existing axes with something like: self.subplot1.change_geometry(2, 2, 3) and delete only those subplots, that aren't needed for further plotting. best regards Matthias On Thursday 04 June 2009 19:33:25 Markus Feldmann wrote: Hi All, i want to change my subplots sometimes, but how to do this ?

Re: [Matplotlib-users] Griddata
I ve a problem with the use of griddata. I have a grid of x,y with value z. the grid have 4500 points I would like to have a rigular grid of 1500 points. I try the function zi = griddata(x,y,z,xi,yi) but I have an error too many indices. I don't understant why!!! x,y,z,xi and yi are numpy array with 1 column. Sorry for my bad english!! Thanks Josh Lawrence-2 wrote: Greetings all, In using the function griddata in mlab.py, I think I have found a bug. The following line in mlab.py errors for me. I supply it an xi and yi that have shape (N,1). I have surface data, but I only care about the variation in one direction. In mlab, when it gets to this line (2956 in svn revision 7040): if min(xo[1:]-xo[0:-1]) 0 or min(yo[1:]-yo[0:-1]) 0: raise ValueError, 'output grid defined by xi,yi must be monotone increasing' the result is an error. That is, I get the following: ValueError: min() arg is an empty sequence A couple of things. First, if I make my variation in x to be 2 points (x = 0 for the case I'm interested in--so I just have both values of x be zero), I do not get this error and I believe the result works. So, it seems that there should be some handling of the case that there are only 1 point in either x or y direction. Second, is it better to use the builtin python function min, or should numpy.min be used instead?

[Matplotlib-users] imshow axis labels
Hi, I'm using imshow to make an image of a 2-d matrix. I use set_xticklabels to adjust the x-axis labels. The problem is that when I then zoom in on the plot, the axis labels are not adjusted appropriately. Does anyone suggestions on how I can fix this?

[Matplotlib-users] The easiest way to check-out matplotlib source
Hello, How do you add you automatically check-out new added files from matplotlib trunk? Is there a specific svn command for this? Another question: For example IPython has uses bzr and when I issue bzr branch lp:ipython command I grab the latest development branch. I do a development installation quoting from IPython documentation: Some users want to be able to follow the development branch as it changes. If you have setuptools installed, this is easy. Simply replace the last step by: $ python setupegg.py develop and one more step: This creates links in the right places and installs the command line script to the appropriate places. Then, if you want to update your IPython at any time, just do: $ bzr pull No duplicated folders and bzr pulls the changes for me. Could this be possible with matplotlib's VCS system?

Re: [Matplotlib-users] imshow axis labels
What are you setting the x ticklabels to? If you want to control how the numbers are displayed, you can create a custom formatter (which is basically a function to convert a floating-point number to a string). If you want to control the number of ticks across the axis, you can make a custom ticker. If you can describe what your end goal is, I'm happy to describe the above options in more detail.

Re: [Matplotlib-users] imshow axis labels
I want to let matplotlib control where the tick marks go, but I want to scale the value of the tick labels. For example, if my matrix has a 100 columns the tick marks might be [0,25,50,100]. I want to scale these tick labels by some value say .01 so that the corresponding tick labels would be [0,.25,.5,1]. Now say I zoom in on the image so that the xaxis limits are (0,50). Lets suppose the tick marks are now [0,10,20,30,40,50] Then in this case the tick labels should be [0,.1,.2,.3,.4,.5] So how do I go about creating a custom formatter?
