Method expandTo

qcustomplot.cpp:4416–4433

! Expands the layout to have \a newRowCount rows and \a newColumnCount columns. So the last valid row index will be \a newRowCount-1, the last valid column index will be \a newColumnCount-1. If the current column/row count is already larger or equal to \a newColumnCount/\a newRowCount, this function does nothing in that dimension. Newly created cells are empty, new rows and columns
