Here I fill the space below the function z = x^2+y^2 to get a solid object. I did it by: Plotting the curves at the…

Here you can sdee Tufte style axes in 3D. The axis affect is achieved by shifting axes, ticks and labels. The command \pgfplotspointouternormalvectorofticklabelaxis{x} is a…

Here we show how contour plots and 3D surface plots can be combined. Pgfplots can compute the z contours by means of gnuplot and its…

We will combine surface and contour plots. We would like the contour lines drawn on the surface to be hidden by the surface in the…

For drawing a spiral cone, we need to find an appropriate parametrization. This code was written by Gonzalo Medina on TeX.SE. \documentclass[border=5pt]{standalone} \usepackage{pgfplots} \pgfplotsset{width=7cm,compat=1.8} \usetikzlibrary{decorations.markings}…

We would like to make an image to illustrate the construction of a spiral capacitor. These are made of spiral coiled films. Itâ€™s like a…

A Moebius strip plot. This code was written by Jake on TeX.SE. \documentclass[border=10pt]{standalone} \usepackage{pgfplots} \pgfplotsset{width=7cm,compat=1.8} \begin{document} \begin{tikzpicture} \begin{axis}[ hide axis, view = {40}{40} ] \addplot3…

We would like to draw a bivariate normal distribution and show where the means from the two variables meet in the space. There are a…
