class altair.ConditionalParameterValueDefGradientstringnullExprRef(param=Undefined, value=Undefined, empty=Undefined, **kwds)#

ConditionalParameterValueDefGradientstringnullExprRef schema wrapper

ConditionalParameterValueDefGradientstringnullExprRef, Dict[required=[param, value]]

Parameters:
paramParameterName, str
