    摘要： The present invention relates to a user interface control for controlling the value of a variable in a processing system. The user interface control includes, a display, an input device and a processor. The processor is adapted to cooperate with the display and the input device to generate an input representation on the display, the input representation allowing the value of the variable to be specified by the user using the input device. The processor then generates a graphical representation on the display, the graphical representation showing a relationship between the variable and a parameter. Finally, the processor generates an indicator on the display, the indicator indicating a value of the parameter for the value of the variable specified using the input representation.
