Do you mean like in the
demo, the left axis? Or really on top of each other? you could try playing with the setOffset or perhaps modifying the QCPAxis to report a minimum margin of 0.
Thanks for the reply.
The closest examples of what i want to achieve are seismogram or F1 lap telemetry plot.
I already tried to hack qcp and achieved to set the axis height and position, but before going further, just want to know if someone has faced this need and found a nice solution.
