Patent ID: 6987381

Claim:
A waveform display position adjusting method for adjusting a position at which a waveform is displayed on a waveform display device which has a two-dimensional display area, said two-dimensional display area having an X-axis and a Y-axis, said method comprising the steps of: continuously adjusting mapping of a waveform input value in a two-dimensional waveform value space to said two-dimensional display area by using continuous adjusting means, said mapping including: defining a memory address space specified by an X-address and a Y-address, said memory address space corresponding to said two dimensional display area including the X-axis and the Y-axis on said display device; generating, from said waveform input signal, waveform value information on a waveform represented by said waveform input signal, and temporal information related to said waveform value information, generating, from said waveform value information, the Y-address for specifying an address in said memory address space; generating, from said temporal information, the X-address for specifying the address in said memory address space; and resetting said mapping to a reference state by using switching means arranged adjacent to said continuous adjusting means.
