 # easy_plot_cpp
 Простая библиотека C++ для рисования графиков 
+
+### Описание
+
+Данная библиотека позволяет рисовать простые графики.
+Пример:
+![example_0 example](img/example_0.png)
+
+### Как установить?
+
+* Инструкция для *Code::Blocks* и компилятора *mingw*
+
+Подключить библиотеку *freeglut* или *freeglut_static*, а также *opengl32*, *winmm*, *gdi32*. 
+Подключить в проекте заголовочный файл *include/easy_plot.hpp*
+Указать С++11 или выше
+
+Для проверки можно запустить код:
+
+```C++
+#include "easy_plot.hpp"
+
+int main(int argc, char* argv[]) {
+    easy_plot::init(&argc, argv);
+	
+    std::vector<double> x = {0,1,0,1,2,0,1};
+    easy_plot::plot("X", x);
+
+	// ставим красный цвет линии
+    std::vector<double> y = {0,2,3,4,2,0,1};
+    easy_plot::plot("Y", y, easy_plot::LineSpec(1,0,0));
+
+    std::vector<double> x2 = {0,2,6,7,8,10,12};
+    easy_plot::plot("XY", x2, y, easy_plot::LineSpec(1,1,0));
+
+	// выводим три графика в одном
+    easy_plot::plot<double>("Y1Y2Y3", 3, x, easy_plot::LineSpec(1,0,0), x2, easy_plot::LineSpec(1,0,1), y, easy_plot::LineSpec(0,1,0));
+
+    while(true) {
+        std::this_thread::yield();
+    }
+    return 0;
+}
+```
