Thanks I appreciate your comments and agree I will have to put some effort in, I tend to try and work things out I need by messing around when I need a specific function or have a specific thing I want to do and focus on that without perhaps learning the underling basics.
I've been spoiled by Excel, there is a lot of stuff its significantly easier (for me anyway) to do without undergoing any learning curve at all, with wizards for functions (for example) and in many cases if you right click on something you can alter it right there, rather than having to go up to the inspector and work out which of umpteen functions the bit you want to alter is hidden in. If the inspector was a person, I would have strangled them to death by now 🙂
I'm not sure if this is my Mac or what, but if I go into numbers help and type anything in, I just get the spinning thing next to the magnifying glass, but it never comes back to me. It works OK if I follow links. For example I just typed 'charts' in help and hit enter, 5 minutes later I"m still waiting. Doesn't increase my confidence 🙂 I'll have to look into that and see whats going on.
Thanks to everyone for your help, the guys will be impressed with the new chart !
