PROBLEM TO BE SOLVED: To display waveform data without damaging the features of the original shape by providing a display control means or the like for performing control to display values based on the waveform data detected by a detection means on the screen of a display means while time sequentially arranging them for each block. SOLUTION: When a zoom-in button is clicked by a mouse, a current magnification value Zoom is made double (S4) and when a Zoom-out button is clicked, the current magnification value Zoom is made into 1/2 (S6). Next, a number SmP of samples per pixel is calculated from this magnification value Zoom (S7). This sample number SmP is correspondent to the width of the block to extract the waveform data characterizing a waveform. Next, the calculated sample number SmP is discriminated and based on the result, a waveform display routine 1 is executed (S9) for displaying the waveform while reducing a time base or a waveform display routine 2 is executed (S10) for displaying the waveform while expanding the time base. |
