I want to add real-time plotting function to nana. Is there any document or demo that using cairo as the backend for plotting?

There are 2 ways to work with cairo.

1, using class "drawing". https://github.com/qPCR4vir/nana-demo/blob/master/Examples/draw.cpp For example in Windows

dw.draw([](paint::graphics& graph)
{
     auto dc = reinterpret_cast<HDC>(graph.context());
    cairo_win32_surface_create(dc);

2, using draw_through to redirectly render on the form. https://sourceforge.net/p/nanapro/blog/2015/01/tour-of-nana-10/

see the section 4, Draw-through of Form
