In QML, zoom functionality is usually achieved by using "scale" property of Item.

Hey i made it in qt creator and i know about scale but i want to do something else.....like i will choose some particular area of my graph and it should be zoomed..like in touch mobile........

Use the scale, do the maths, and it will show you only what you need :) There is no built-in mechanism for getting that, AFAIK.

Have a look at "Qt5 Everywhere Demo":https://qt.gitorious.org/qt-labs/qt5-everywhere-demo/source/9a868f96ee63c21ceda890d8dfc9d33f093d1b6d. May be you will get some idea.
