 h English (en)// For xy plot using KplotWidget
   this->xyPlot = xyPlot; //set pointer
   xyPlot->setMinimumSize( 600, 600 ); //set minimum size in pixel
   xyData = new KPlotObject( Qt::red, KPlotObject::Lines, 2 ); //the data lines are drawn in red with thickness 2
   xyPlot->setLimits(0, 100, 0, 600); //the data limits are 0 to 100 in the x-direction and 0 to 600 in the y-direction (initially we start at point 590)
   xyPlot->addPlotObject(xyData); //assign the data pointer to the graph. From now on, if the data pointer contains data, it is plotted in the graph
   xyPlot->setBackgroundColor( QColor(240, 240, 240) ); //background: light shade of gray
   xyPlot->setForegroundColor( Qt::black ); //foreground: black
   xyPlot->axis( KPlotWidget::BottomAxis )->setLabel("Time [s]"); //set x-axis labeling
   xyPlot->axis( KPlotWidget::LeftAxis )->setLabel("Position [m]");    //set y-axis labeling
