I am doing a project on CalculiX data visualizor,using Qt.I 've to draw the structure and after giving force the displacement should be shawn as variation in color.I chose HSV coloring,but while executing I got an error message:"QColor::from Hsv:HSV parameters out of range".The code is: DataViz1::DataViz1(QWidget *parent) : QWidget(parent), ui(new Ui::DataViz1) { DArea = new QGLScreen(this);
