Claim:
1. A method for scale adjustment in touch-based measurement equipment, comprising steps of: providing a touch-based screen of measurement equipment with a waveform area; determining if a first-direction gesture or a second-direction gesture is present on the waveform area, wherein the first-direction gesture is determined to be present on the waveform area when two fingers simultaneously touch two separate points on the waveform area and a first inclination angle included between a line passing through the two points and a first direction of the waveform area is less than a threshold, wherein the second direction gesture is determined to be present on the waveform area when two fingers simultaneously touch two separate points on the waveform area and a second inclination angle included between a line passing through the two points and a second direction of the waveform is less than a threshold; when the first-direction gesture is determined to be present, incrementing or decrementing a first scale of testing signals in a stepwise manner under a first scale adjustment mode; and when the second-direction gesture is determined to be present, incrementing or decrementing a second scale of testing signals in a stepwise manner under a second scale adjustment mode, wherein when the first-direction gesture is determined to be present on the waveform area, the first scale adjustment mode is entered and a first scale adjustment bar is displayed elongated in the first direction on the waveform area, and when the second-direction gesture is determined to be resent on the waveform area, the second scale adjustment mode is entered and a second scale adjustment bar is displayed elongated in the second direction on the waveform area.
