cvplot

Graph plots, drawing, layout and windows in OpenCV.

About

Yet another cvplot library? Yes. Because they're all pretty bad. Like this one.

Build

Install the dependencies CMake and OpenCV. If you're on macOS, use Homebrew:

brew install cmake opencv

On Ubuntu:

apt-get install cmake libopencv-dev

Next build using CMake. The easiest way:

make

Internally it creates a build folder and runs CMake from there.

This project is developed and tested on macOS and Ubuntu.

Example

To draw a simple line graph:

cvplot::figure("myplot").series("myline")
  .addValue({1.f, 3.f, 2.f, 5.f, 4.f});
cvplot::figure("myplot").show();

cvplot example

Features

  • Graphs: line, histogram, scatter
  • Time series, parametric, range
  • Automatic and dynamic coloring
  • Transparency
  • Image and text drawing
  • Sub-windows (views)
  • Window and view layout
  • Green view frame
  • Mouse support
  • OpenCV-like API (highgui)
  • Distinguished dated look

Demo

To see some of the plotting in action, run the demo:

make demo

cvplot demo

The style of windows and colors are intentionally pale and pixelated to give a dated feel to the whole thing.

Test

If googletest is available on your system, run tests with:

make test
