plotter

plotter is a plotting library for C++, which aims to provide easy to use functionalities.

Installation

Install SDL2pp

First install basic dependencies :

• A compiler
• make
• cmake
• ninja

On Debian-based systems, run :

sudo apt install build-essentials ninja cmake

Follow instruction at : https://github.com/libSDL2pp/libSDL2pp?tab=readme-ov-file#building, install the library system-wide.

Linux

Then, run :

git clone https://github.com/crespinl/plotter.git
cd plotter
make

Windows

I never tried

MacOS

I never tried

Run

Create a basic test program in a separate directory : In a CMakeLists.txt file :

cmake_minimum_required(VERSION 3.26)

project(test)
find_package(plotter REQUIRED)

add_executable(test main.cpp)
target_link_libraries(test plotter::plotter)

In a main.cpp file :

#include <vector>
#include <plotter/plotter.hpp>

using namespace std;
using namespace plotter;

int main()
{
    Plotter plotter { "Test Plot", "x axis", "y axis" };
    vector<Coordinate> coordinates;
    for (int i = 0; i < 100; i++)
    {
        float v = (float)i / 10.;
        coordinates.push_back({ v, sin(v) });
    }
    plotter.add_collection({ coordinates, "A sinus", DisplayPoints::No, DisplayLines::Yes });
    plotter.add_collection({ vector<Coordinate> { { 0, 0 }, { 10, -8 }, { -10, -8 }, { -10, 8 }, { 10, 8 }, { 0, 0 } }, "A beautiful set", DisplayPoints::Yes, DisplayLines::No });
    return !plotter.plot();
}

Build the CMake project and enjoy !
