Re: [Matplotlib-users] bar charts (Margherita Vittone wiersma)

2007-01-26 Thread Yannick Copin
Hi, i have made bar charts but I was wondering if there is a way to show on top of each bar the real content/counts, like a label; I generate static plots so the dynamic showing of the counts on focusing on the bar does not help me. Cannot you just add the counts manually? E.g. x,y =

Hi, using Agg, there's problems exporting plots in pdf format, all accentued characters are not displayed (like u'accentué'), but they are in svg files. In svg files, superscript characters are set to subscript (using TeX notation). Is there solutions to these problems? thanks -- Lionel

I'm trying to learn about 2D fourier transforms and k-space right now. To do this, I'm using the image at http://django.jayparlar.com/4kSnake.png In Matlab, I run the following code: Im = double(imread('4kSnake.png')); FT = fftshift(fft2(Im)); FT_Amp = abs(FT); minAmp = min(min(FT_Amp)); maxAmp

I'm trying to work out a way of printing plots as vector graphics that use alpha channel. I understand that postscript doesn't do alpha, so I was hoping to save the plot as svg, import into illustrator and then save as a pdf and/or print. So I run the following file: (matplotlib svn 2943, os x,
