I have the following problem I am facing. I have multiple line graphs (vertically aligned) and all of them share a common x-axis. They are all in QCPLayout and further belong to common margin group to keep y-axis aligned. However, I would like to keep the topmost graph pinned and the rest of the graphs can be scrolled through (as there can be up to 32 such graphs). How do you achieve pinning in QCP layout so that the other graphs slide under the top-most graph?
