Oh DocHH, axis's, axes, hatchets, graphs.....you know my maths phobia....shall work backwards far easier than trying to work out what a thingy of a graph is!
Haven't had a further look again as have been having a skive off - had a trip down to the Mammoth Onion nursery (a REAL nursery not a garden centre) to get the cucumbers and another couple of tomatoes - got a Black Prince and a Redcurrant tomato plants from their old Heritage series and another previously unknown (to me) variety, Cherry 100's that makes 12 different plants 6 x new and 6 x old faithfuls. Naturally, it involved a meeting with a friend and lunch! Will have another look at bedtime.
Physicsgirl, hope minipg is well on the mend.
