If we have in mind the following procedure:

BACo3 (s) + H + 1 - > Ba + 2 + HCO3 - 1

CO3 - 2 + H+1 - > HCO3 - 1

As nitric acid is added then {CO3 - 2 } decreases meaning that more BaCo3 can dissolve. The graph you need to use is the one that the curve goes down and closer to solubility and goes up on conc.
