  • parametric curves
  • implicit curves f(x,y) = 0
  • can use mathematical functions from other libraries like gsl
  • can use LaTeX to display text and formulas
  • animations
  • Matrix or grid display
  • ...

• 3D plots

  • parametric surfaces
  • 3D graphs z = f(x,y)
  • interactive 3D rotation and zoom
  • ...

• Many renderers

  • GPU graphics (opengl/sdl)
  • Graphics package

GUI

An official standalone GUI for oplot.0.72: goplot

Examples

The top directory contains examples that can be run from the ocaml toplevel. See the README file.

Install version >= 0.80

The current version does not require lablgl, but uses instead tgls and gl-legacy. They will be automatically installed if you use opam install oplot.

If you need the newest versions:

opam install tgls
opam pin https://github.com/sanette/gl-legacy.git
opam pin https://github.com/sanette/oplot.git

On Windows, you may need to select these tsdl* versions:

opam pin https://github.com/sanette/tsdl
opam pin https://github.com/sanette/tsdl-ttf.git
opam pin https://github.com/sanette/tsdl-image.git
opam install oplot

Install v 0.72

• oplot<0.80 requires lablgl. If you have any trouble with this, try this one.:

opam pin add https://github.com/sanette/lablgl-lib.git
opam install lablgl.1.07-lib
opam install oplot.0.72

Requirements

• For PDF output you need to install the fig2dev system package.

• For LaTeX display you need a working LaTeX installation; for instance install the texlive system package.

• For using the Gnu Scientific Library, install the gsl opam package:

opam install gsl

• For rendering via the OCaml Graphics library (currently not recommended), you need to use the oplot-graphics opam package.

Extensions to other backends

It's easy to add another backend by using the GRAPHICS signature, see https://github.com/sanette/oplot-graphics
