Увеличить дальность прорисовки q3dsurface

Количество точек на графике 100000. Для вывода графика пользовался примером:Surface example.

main.cpp

#include <iostream>
#include "mainwindow.h"
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow window;
    QVector<double*> data;
    double tstep = 0.06, xstep = 0.01;
    data.reserve(1000 * 100);
    for (int t = 0; t < 1000; ++t)
    {
        for (int x = 0; x < 100; ++x)
        {
            data.push_back(new double[3]{static_cast<double>(x) * xstep , std::sin(t * tstep * (x * xstep) * (x * xstep)),  static_cast<double>(t) * tstep});
        }
    }
    window.dataReceived(data);
    window.show();
    return a.exec();
}

    ui->graph->addSeries(series);
    gr.setColorAt(0.0, Qt::black);
    gr.setColorAt(0.33, Qt::blue);
    gr.setColorAt(0.67, Qt::red);
    gr.setColorAt(1.0, Qt::yellow);
    ui->graph->seriesList().at(0)->setBaseGradient(gr);

}

Необходимо чтобы график полностью был отрисован (отсутствовали серые области).
