Graph plots, drawing, layout and windows in OpenCV.
Yet another cvplot library? Yes. Because they're all pretty bad. Like this one.
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.
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();
- 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
To see some of the plotting in action, run the demo:
make demo
The style of windows and colors are intentionally pale and pixelated to give a dated feel to the whole thing.
If googletest is available on your system, run tests with:
make test
