How to make nice looking plots with TikZ/pgfplots
Anders Mannesson wrote a very good, and also very beautiful, thesis called Joint Positioning and Multipath Radio Channel Estimation and Prediction. He has also described the Matlab and TikZ/pgfplots files he used to produce the various plots in the document plotDocumentation.pdf. All TeX and Matlab files used in that document are available in codeInput.zip.
