I plot graph in my article with the command '\begin{tikzpicture} ..\end{tikzpicture}'. First, I extract datas from matlab in a text file and I use \addplot with all the options. It is great, but my compilation is very very long ( I have a lot of figures ). Is it possible to have all the figures in tikz external files ( which I can modify sometimes ) and convert into a pdf file (because using \includegraphics with a pdf file is very fast) ?

This happens because PGFPlots only uses one "stack" per axis: You're stacking the second confidence interval on top of the first. The easiest way to fix this is probably to use the approach described in "Is there an easy way of using line thickness as error indicator in a plot?": After plotting the first confidence interval, stack the upper bound on top again, using stack dir=minus. That way, the stack will be reset to zero, and you can draw the second confidence interval in the same fashion as the first:

You have got:
- source PDF
- target PDF
The PDF format is a box and I have no idea how you produce this source PDF. My guess is that the source PDF contains the graphs in a format which can not be used directly by pdfLaTeX, but "fortunately" there is a background software included in your TeX-installation, which produces a large jpg or an eps file from your source PDF while compiling and this jpg is included in your target PDF.
I'm neither an expert on PDF, nor on pdfLaTeX. But could you describe a bit how you produce the source PDF?
OK, however, shrinking a large PDF is possible as well. There is a software called "pdfsizeopt.py", I've been using it for years, on windows as well as on linux.
To avoid trouble with embedded fonts in embedded figures, the first line of my *.tex file is:
\pdfinclusioncopyfonts=1

You can process your
tikzpictures as standalone documents and then include them as pictures. E.g., the filemyplot.texmight containYour main document then includes the generated pdfs:
