Title
Body
I am using Qt and C++ as my environment. I draw a QGraphicsView in my UI, then create a scene and add lines to that it. I run through an array of 5000 points and draw lines connecting each point. QGraphicsScene *scene = new QGraphicsScene(); QPen pen2 = QPen(Qt::blue, 8.0); int j=1; for (int i=1; i<5000; i++) { scene->addLine(xArray[i],yArray[i],xArray[j],yArray[j], pen2); j++; } The problem is that the numbers I am grabbing are very small. e.g., 2.000e-12 . The numbers will consistently change based on the application. How can I adjust my scene to stretch to fill my QGraphicsView . Now, all I see is a dot in the center of my view.
