示例1: update
bool BarGraph::update(const GRT::VectorDouble &sample ) {
if( !initialized ) return false;
this->data = sample;
//If the plot is hidden then there is no point in updating the graph
if( this->isHidden() ) {
return true;
}
QCustomPlot *plot = ui->graph;
QVector<double> keyData;
QVector<double> valueData;
QVector<double> tickVector;

//Add the data to the graph
for(unsigned int k=0; k<K; k++) {
