A method including displaying an orthogonal grid on a touchscreen display. The touchscreen display is in communication with a test and measurement instrument. The orthogonal grid has an axis that is associated with a controlled output parameter of the test and measurement instrument. The method also includes detecting a touch input at the touchscreen display. The touch input includes a continuous slide gesture made by a user substantially along the axis of the orthogonal grid. The slide gesture begins at a first location on the axis and ends at a second location on the axis. Also, the method includes adjusting the controlled output parameter of the test and measurement instrument from an initial value to an adjusted value. The initial value corresponds to the first location of the slide gesture and the adjusted value corresponds to the second location of the slide gesture. Systems are also disclosed.
