Redraw function by using canvas

[A Former User]

I am trying to make a graph in qml by using canvas(the same one which is used in html5). I need to redraw the screen every second or so.Is there any function which could update the screen? I want to draw the animation graph which can update value every second.

You can use "Timer":http://qt-project.org/doc/qt-4.8/qml-timer.html to trigger "requestPaint":http://qt-project.org/doc/qt-5.0/qtquick/qml-qtquick2-canvas.html#requestPaint-method or "markDirty":http://qt-project.org/doc/qt-5.0/qtquick/qml-qtquick2-canvas.html#markDirty-method Canvas methods every second
