Probably there is no chart for this. Because it depends on how you vary the pH.

You have to solve the simultaneous equations of the Solubility Product, the water dissociation and (if you are using a weak acid or base) the dissociation of that acid/base

Say, for example, that you increase the pH using sodium hydroxide. You will end with a solution of sodium sulfate and lead hydroxide. So...what "solubility" means here?

If you decrease the pH using sulfuric acid, you have the common ion effect. If you use nitric acid to lower the pH you may get differnt result.
