Abstract: A method and apparatus for facilitating user interaction with a measurement instrument displays a control knob glyph corresponding to a user-adjustable parameter of the measurement instrument, the control knob glyph having an indicator and a partially circular drag area through which the indicator can be rotated. Inputs indicating amounts of rotational movement for the indicator can be received, and the location of the indicator within the drag area and the value of the parameter changed in response to such inputs.

Abstract: A real-time data display in a control window of a measurement instrument receives real-time data corresponding to an application, wherein the real-time data is to be displayed to a user. A control window is also displayed, including one or more user-selectable options within the control window and at least a portion of the real-time data within a portion of the control window. A user selection of an option to alter a display of the real-time data is then received, and the real-time data being displayed is altered within the portion of the control window in accordance with the user-selected option.
