fixes: #358

This was displaying weirdly because TraceRequiredPanel was returning a Panel and so was AxisRequiredPanel. So there were two panels wrapped in one another.
I refactored this code a little so that AxisRequiredPanel is not needed and instead we can add extra conditions to the TraceRequiredPanel, along with extraEmptyPanel messages.
