QCustomPlot Discussion and Comments

Hello. I'm using QCPLayoutGrid to arrange 4 elements in one plot.

mPlot->plotLayout()->clear();
QCPMarginGroup* marginGroup = new QCPMarginGroup(mPlot);
subLayout = new QCPLayoutGrid;
for (int i = 0; i < 4; ++i) {
    QCPAxisRect *subRectLeft = new QCPAxisRect(mPlot, false);
    subRectLeft->addAxes(QCPAxis::atBottom | QCPAxis::atLeft);
    subRectLeft->axis(QCPAxis::atLeft)->ticker()->setTickCount(2);
    subLayout->addElement(i, 0, subRectLeft);
    subRectLeft->setMarginGroup(QCP::msLeft, marginGroup);
}

mPlot->plotLayout()->addElement(0, 0, subLayout);

I also need to dynamically hide/show elements in the layout.

auto* it = subLayout->elementAt(idx);
it->setVisible(enabled);
subLayout->updateLayout();
mPlot->replot();

When an item is hidden, the layout has empty space, i.e. visible elements are not resized to fill the gap https://postimg.cc/14RkN0JM. Is it possible to fill the gap? Or do I need to re-implement the resizing within QCPLayoutGrid and QCPLayout?

Thank you in advance.
