display the loadsheet graph showing the calculated data ..adequately and correctly plotted
reasonably straightforward ..
(a) plot on the weight by index unit chart .. not weight by CG
(b) most (and probably all) loads (other than fuel) will present as straight lines eg seats, cans, etc
(c) fuel will be a complex line and you will need to look at the variation of fuel arm with volume .. if you can scan the relevant pages from the Airbus manual we can talk you through that .. quite easy once you see how to go about it
The only element of difficulty is to find out how to plot at pixel level on your system ... plus the inevitable and painful process of including sufficient error trapping routines to make the software reasonably idiot proof ....
