The way you described it is fairly accurate. This graph should have fairly linear attributes to it, with the exception being that typically I don't bring the line all the way to -100%. I will usually do a very smooth gradual curve in the vacuum section, and leave it at around -80% at the most.
Your setpoint (the line you're creating) should cross through the 0 Load and 0% intersection as close as possible.
For every 14.7 PSI boost, you should be adding around 100%. So at the 14.7 psi loadpoint, you should be at 100%, and for 29.4 psi loadpoint, you should be at 200%.
Of course, you will never land smack dab perfect on the AFR's using that theory due to chokepoints and efficiencies of either the turbine or compressor.
When dealing with a large turbo, usually the line will start out a little below the assumed targets with the lower boost pressures since a large turbo is much less efficient at lower boost pressures. As boost pressures increase, your line will start taking a more aggressive curve upward until you start reaching the choke limits of either the turbine or compressor (whichever begins to choke up first). Then your line will begin to plateau.
