Good question. Column profile is set by two parameters, one is bubble point and second one is available utility conditions (such as, available steam pressure & hence steam temperature in case steam being the heating fluid, that governs column bottom temperature). Temperature gradient refers to the difference in temperature between the top and bottom of the column. Ideally, the temperature at the bottom of the column should be near the boiling temperature of the solution in the stillpot, and it should decrease continually in the column until it treaches the boiling point of the more volatile component at the head of the column.
