[Matplotlib-users] Problems y_label - bar chart
Hi Folks! I want to create a bar chart having 85 different Objects, each Object owning a certain name of four letters -- I followed the examples on the matplotlib examples page - so far so good. I have some problems with the y_labeling because every objects name is overlaid by it' s neighbour and so a proper assignment is not possible. I tried to change the bar size, but that did not have any effect on the y_label. Is it possible to display the object names vertical 1 y k 7 instead of horizontal (1yk7) to obtain a better readable figure? or maybe some of you have a better idea? - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users

In the barchart_demo.py example, you can add to the text command the keyword argument rotation='vertical' (or give a number for angle in degrees).

[Matplotlib-users] ANN: Python programs for epidemic modelling
Dear lists, DeductiveThinking.com now provides the Python programs for the book of M. Keeling P. Rohani Modeling Infectious Diseases in Humans and Animals, Princeton University Press, 2008. The book has on-line material which includes programs for different models in various programming languages and mathematical tools such as, C++, FORTRAN and Matlab, while some are also coded in the web-based Java programming language to allow readers to quickly experiment with these types of models, as it is stated at the website. The Python version of the programs were written long ago and submitted to the book's on line material website (available soon). The Python programs with the basic equations modelled and the results in figures were now uploaded on a special wiki page of DeductiveThinking.com. Since, the programs are heavily using numpy, scipy and matplotlib libraries, I send this announcement to all the three lists and the main python-list; sorry for double-posting. The announcement with the related links is uploaded here http://blog.deductivethinking.com/?p=29. The programs are at http://wiki.deductivethinking.com/wiki/Python_Programs_for_Modelling_Infectious_Diseases_book. For those who are interested on modelling and epidemiology, they can take a look at the main site (http://deductivethinking.com) or the main page of the wiki (http://wiki.deductivethinking.com) and follow the epidemiology links. The website is in its beginning, so limited information is uploaded up to now.

[Matplotlib-users] regression coeffiecients
Hello, I'm having troubles understand something about regression coefficients. If I have two vectors: x = [1.38, 1.98, 3.18, 3.56, 4.9, 6.21, 6.44, 7.47, 8.36, 8.81] y = [8.19, 17.77, 20.12, 14.55, 20.17 ,31.22 ,28.94, 34.79, 40.26, 38.99] and I would like to find out the regression coefficient I can use polyfit: b1, b = polyfit(x,y,1) my first question is can I get from polyfit the corrlation coeficient (I know about corrcoef, just looking for more opotions). The second question is about a fuction I wrote: according to http://en.wikipedia.org/wiki/Regression_analysis#Linear_regression it's pretty easy to write a little python funcion to calculate the regression coefficients. Here is mine: def b1(x,y): sum1 = 0 sum2 = 0 mx = mean(x) my = mean(y) for i,j in zip(x,y): sum1 =+ (i-mx)*(j-my) print sum1 sum2 =+ (i-mx)**2 b1 = sum1/sum2 return b1 both methods yeild two different b1 values. Can anyone please tell me what wrong with my function ? Thanks, Oz. -- .''`. : :' : We are debian.org.

[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?

I hope it is ok, Well, that depends what you mean by ok. Obviously, the author picks the license s/he prefers. But a GPL license means that some people will avoid your code, so you make wish to make sure you thought the licensing issue for this code carefully. As a point of comparison, note that all your package dependencies have a new BSD license.

[Matplotlib-users] Why is wrapper module called pylab ?
So is matplotlib the name of the low level plotting engine? And, pylab is the user-friendly wrapper? Would it be ok to call the whole system Pylab instead of Matplotlib then?
