I have used 'syntax' to use 'factors'. Works perfectly but I still don't
know what factors are. Have been using them everywhere without
understanding :-)

your x-axis appears to be incorrect because your 'duration' field

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.
