The coordinates of the new points along the y axis and given in the user unit system. */ void vpPlot::plot(const unsigned int graphNum, const double x, const vpRowVector &v_y) { if((graphList+graphNum)->curveNbr == v_y.getRows()) { for(unsigned int i = 0;i < v_y.getRows();++i) this->plot(graphNum, i, x, v_y[i]); } else vpTRACE("error in plot vector : not the right dimension"); }
