How to hide the grid and show only caroline in QCustomPlot?

Question

Is there a way to show a null value in QCustomPlot by hiding the grid? I tried to hide the grid with the following line:

ui->customPlot->xAxis->grid()->setVisible(false);
ui->customPlot->yAxis->grid()->setVisible(false);

But it also hides zeros. I need to keep the zeroers visible.

Answer 1

Set Qt::NoPento QCPGrid::setPen/ setSubGridPenbut not setZeroLinePen.

Answer 2

Current->xAxis->grid()->setSubGridVisible(false); 
Current->yAxis->grid()->setSubGridVisible(false);
