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); DArea->setGeometry(QRect(10,10,700,600)); //TODO This values are feeded by user dfile="/home/41407/color.txt";//input file with displacement mfile="/home/41407/mesh21.txt";//input file nodeId="*NODE"; elId="*ELEMENT"; DataId="displ";

parseMfile();
parseDfile();
DArea->Nodes=Nodes;
DArea->Elements=Elements;
DArea->Data=Data;
DArea->fillColorArray();
//printf("Colr is %d",DArea->pickColor(-11.02,0));fflush(stdout);

ui->setupUi(this);

}

DataViz1::~DataViz1() { delete ui; } void DataViz1::parseMfile() { QFile file(mfile); if (!file.open(QIODevice::ReadOnly | QIODevice::Text)) return; int node_end=0; QTextStream in(&file); in.skipWhiteSpace(); while (!in.atEnd()) { QString line = in.readLine(); if(line.startsWith(nodeId))//Node block in Mfile { while(1) { line = in.readLine(); if(line.startsWith(elId)) { break; } Nodes< 

             while(1)
             {
                    line = in.readLine();
                    Elements<<line;
                    //printf("Element is %s\n",line.toLocal8Bit().constData());fflush(stdout);
                    if(in.atEnd()) break;

            }
         }
     }

}

void DataViz1::parseDfile() { QFile file(dfile); if (!file.open(QIODevice::ReadOnly | QIODevice::Text)) return; int node_end=0; QTextStream in(&file); in.skipWhiteSpace(); while (!in.atEnd()) { QString line = in.readLine(); if(line.startsWith(DataId)) { continue; } line = in.readLine(); Data<
