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…

The sine function is a well known periodic function. Choose an argument factor, which doesn’t divide the period well, and you can see a complicated…

The sine function is a well known periodic function. Choose an argument factor, which doesn’t divide the period well, and add another sine function with…

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…

The Mandelbrot consists of points whose boundary is a two-dimensional fractal shape. It is named after the mathematician Benoit Mandelbrot. It’s computed using a lot…

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…

The Weierstrass function is a pathological one: is continuous everywhere but differentiable nowhere. The original code was written by Herbert Voss on TeX.SE, Stefan Kottwitz…
