hi friends,
how can i map a scene coordinate of rect (-1000,-1000, 2000, 2000) to a cartesian map coordinates.
im having range and bearing value from which i converted in to cartesian points and now i want to show the points in the QGraphicsview as like mathematical graph
i can position it using polygonItem but how to convert sceneRect to mathematical graph
where
in graph topLeft (-x, +y) topRight( +x, +Y) bottomLeft( -x, -y) bottomRight ( +x, -y)
but our scene coordinates are topLeft(-x, -y) topRight(+x, -y) bottomLeft(+x, -Y) bottomRight(+x, +y) .
please help me how i can plot the item on the scene.
Thnx in advance
