有人能建议我一个很好的，免费的，易于使用的库为C ++允许绘制数学函数用于Microsoft Windows的窗口？ （例如抛物线X ^ 2 + 5X + 3 = 0）

Someone can suggest me a good, free, easy to use library for c++ that allow to draw a mathematical function in a window for microsoft windows? (e.g. the parabola x^2+5x+3=0)

推荐答案

另外wxWidgets的基础选择是 wxArt2D ，它得到了吨好等特点绘制数学函数的曲线，就像你可以很容易地通过这个 Y = 140 * COS（X / 20）+ 80 * COS（X * 2/20）+ 40 * COS（ X * 4/20）以曲线对象，它会拿得出，这是惊人的！ 查阅这些截图有一些曲线，通过的方程绘制字符串的格式！

Another wxWidgets-based option is wxArt2D, It has got tons of good features for drawing mathematical functions as curves, like you could easily pass this y=140*cos(x/20) + 80*cos(x*2/20) + 40*cos(x*4/20)" to a curve object and it will get drawn, it's amazing! Check out these screenshots there are some curves drawn by equations in string format!
