Robin 200 & W&B problems

Dear All,
I've read the forums and also the help on skydemon website for how to setup the W&B.
However, I seem to be struggling.
The w&B 'polygon' has the correct numbers on x & y axis, to reflect exactly that in the PoH (x axis m.kg, y total weight, kg)
However despite various attempts at putting the invidual moments for passenger, fuel etc., the 'X" is way off the graph (which is not the case when I do this manually).
I'm a little confused about whether I need to redo the x-axis. Can anyone help please?

You've got the same issue as the other poster I replied to. Your envelope is for a moment, not a CG

Also, it's a bit confusing as your empty weight is 576kg yet your graph starts at 400kg

I found another POH online here - I accept that it's not necessarily for the same aircraft, but the rest of the values are the same.

This gives a loading envelope of:-

22,580, 32,780, 46,780, 46,580

(this also matches the figures you gave of .32 to .46 at 780kg)
