Making plot in Qt
c++, plot, qt, user-interface
Solution
I strongly recommend Qwt.
Qwt is a mature, well-documented library and, I think it's fair to say, the standard solution for implementing plots and other display and control widgets in Qt.
If you need 3D plots, try QwtPlot3D.
Problem
I need to implement some plot like that or that in my app , it can be even something similar. I made a search on Qt web site with no progress , and I saw Qwt package but nothing similar there. Any ideas?
