Re: [Matplotlib-users] csv2rec column names

2009-01-03 Thread Anton Vasilescu
The recarrays were what csv2rec is returning and that's why I was using it. And this afternoon was the first time I was hearing about red arrays so I was trying to get my stuff done with the wrong tool. I've changed my code to use regular txt file loading and all works great. Thanks everybody f

[Matplotlib-users] Text zoom font size

2009-01-03 Thread ulrichD
Hi, I am extensively using the great interactive features of pylab. I'd like to use text in my figures and make it become larger when I zoom into it. (now it always remains the same absolute size in the figure). Is there a way to do this? (maybe its even possible to only show the text when a ce

[Matplotlib-users] polar clockface

Hi all, Does anyone know if it's possible to make the polar plot look like a 12- or 24-hr clockface? I.e. 0 (or 12) at the top rather than the right, and labelled in 12ths (or 24ths) instead of degrees? Thanks, G ---

FYI, I recoded np.loadtxt to handle missing data, automatic name definition and conversion functions, as a merge of np.loadtxt and mlab.csv2rec. You can access the code here: https://code.launchpad.net/~pierregm/numpy/numpy_addons Hopefully these functions will make it to numpy at one point or

You're right! I read more about recarrays and they were built specially for being called by the column name, so I shouldn't have used csv2rec from the start! Thanks for the quick responses! Anton Patrick Marsh-2 wrote: > > In my limited opinion, numpy's loadtxt is the way to go. Loadtxt > d

In my limited opinion, numpy's loadtxt is the way to go. Loadtxt doesn't care about the headerYou can read in the arrays like this: # read in all 5 columns as text col1, col2, col3, col4, col5 = np.loadtxt(filename, dtype=dtype, unpack=True) or if you want to skip the column headings and read in

I am plotting the data in those csv files and the forst 4 columns in the files have the same title but the 5th has the name based on the date and time so it would be unique in each of the files. As I have about 600 files to batch process, adjusting my script manually is not an option. The way I h

I'm not sure what you are needing it for, but I would suggest looking into numpy's loadtxt function. You can use this to load the csv data into numpy arrays and pass the resulting arrays arround. -Patrick On Sat, Jan 3, 2009 at 11:21 AM, antonv wrote: > > Hi all, > > I have a lot of csv fi

Hi all, I have a lot of csv files to process, all of them with the same number of columns. The only issue is that each file has a unique column name for the fourth column. All the csv2rec examples I found are using the r.column_name format to access the data in that column which is of no use fo

Hi list, When the 'pylab' module is loaded the function 'strtod' does not work well. I suppose that this is not new: http://www.python.org/search/hypermail/python-1994q2/0750.html and the question is: any solution? In this linkit exists a better description of the problem: http://mbdynsimsuit
