Torus Basic plot from data using Gnuplot.3D from a function, wire and surface plots.Just like contour, this command sets up a pretty basic heatmap for more control, see gnuplot's documentation. The labels can be disabled if labels=false is passed as an argument: contour(x, y, (x,y) -> 5cos.(x/2).*sin.(y/2), labels=false) Plotting heatmaps For much more detail, see gnuplot's documentation. The contour command sets up pretty generic contours, which hopefully are useful in many cases. Gnuplot's contour support is quite flexible. The equivalent to plot! is surf!: surf!(x, y, (x,y) -> cos.(x./2).*sin.(y./2)-3, lc = :orange, w = :l) Plotting contours Hidden3d = :on)) Plotting multiple surfaces with surf! Consider the function (x,y) -> sin(sqrt(x*x+y*y))/sqrt(x*x+y*y).
Pm3d gnuplot how to#
Palette = :summer)) How to plot a 3-D functionĪ 3-D function defines a surface for a given set of x and y samples. In other words, z is the surface at x = 0, y = 0 and z is the coordinate at x = 0, y = 2. Note that the matrix of z coordinates is defined so that the columns are indexed by the x coordinates. Z = Īxes(title = "'3D: Valley of the Gnu from gnuplot manual'")) Note that the data may be plotted as a wireframe (with plot style lines, which is the default), or as a surface ( pm3d) with an optional palette. Plotting them is just a matter of providing the data to gnuplot.
In addition, the following commands are specialized for different types of 3-D plots: CommandĪ set of 3-D coordinates may be explicitly given. These are very similar to plot, except for the z coordinate, which is a matrix that specifies the z-coordinate of the points specified in x and y. Three dimensional plots can be created with the commands surf and surf!.
