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.
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.
I love QCustomPlot which is a Qt C++ library. It focuses on making good looking, publication quality 2D plots, graphs and charts and also has high performance for real-time visualization applications. You can get it here: http://www.qcustomplot.com/
