示例1: on_horizontalSlider_valueChanged
void Window::on_horizontalSlider_valueChanged(int value)
{
QCPRange range = ui->plot->xAxis->range();
double real_size = range.size() / old_x_slider_scale;
double new_size = real_size * value;
old_x_slider_scale = value;
ui->plot->xAxis->setRange(QCPRange(range.center() - new_size / 2, range.center() + new_size / 2));
ui->plot->xAxis2->setRange(QCPRange(range.center() - new_size / 2, range.center() + new_size / 2));
ui->plot->replot();
}示例2: yAxisChanged
void MainWindow::yAxisChanged(QCPRange range)
{
ui->verticalScrollBar->setValue(qRound(-range.center()*100.0)); // adjust position of scroll bar slider
ui->verticalScrollBar->setPageStep(qRound(range.size()*100.0)); // adjust size of scroll bar slider
}示例3:
void AP2DataPlot2D::xAxisChanged(QCPRange range)
{
ui.horizontalScrollBar->setValue(qRound(range.center())); // adjust position of scroll bar slider
ui.horizontalScrollBar->setPageStep(qRound(range.size())); // adjust size of scroll bar slider
}示例4: yAxisChanged
