Blackcoin would be a straight vertical line (representing the pow phase in the week it launched) and then the inflation would start above 100% as there's no hard supply cap, only a soft one determined by the 0.97% inflation (of the starting supply)    

Blackoin inflates with 739k each year, like 1% but that percentage decreases due to inflation being a flat rate rather than proportional. 

That's not the full picture though considering the context. BLK happened to be launched during a miningpool craze where everyone just mined the most profitable coins and immediately sold them on exchanges. It's most likely that's where most of BLK's early coins ended up.

Doge and Dash both started with a year of hyperinflation. Fairly okay for proper dispersion.

On the other hand, Ripple and NEO can't even be mined. These coins can make new supply at will, whenever the team needs it.
