    • however,i don't know how to draw accumulated histogram by MFC.MFC, being a general application framework, offers no specific functionality for drawing histograms. You will have to use GDI calls like MoveTo, LineTo, TextOut etc. to draw the histogram as you like. Since you will most probably draw the histogram to a CView (or derived) window, implement the view's OnDraw() and use the DC you get there for your GDI calls.
