Shape control for electrical stimulation therapy

A system comprising:

• a memory;
• and
• processing circuitry operatively coupled to the memory and configured to:
• receive, via a lock button presented in a user interface, user input requesting a relationship of first values of a therapy parameter to be locked for multiple electrodes of a plurality of electrodes;
• receive the first values of the therapy parameter for each respective electrode of the multiple electrodes;
• define, based on the first values, the relationship for the multiple electrodes of the plurality of electrodes, wherein the relationship defines a ratio of the first values of the therapy parameter between the multiple electrodes;
• perform a master adjustment that adjusts each first value of the therapy parameter for each respective electrode of the multiple electrodes by an amount specified by the relationship to determine second values of the therapy parameter for each respective electrode that maintains the ratio of the first values of the therapy parameter between the multiple electrodes;
• and
• control delivery of electrical stimulation according to the second values of the therapy parameter for each respective electrode.
