PROBLEM TO BE SOLVED: To provide a recorder capable of easily comparing and verifying measurement data at historical trend mode. SOLUTION: The recorder records various types of measurement data inputted from the outside and has a historical trend mode display function, capable of scrolling a waveform display region in a time-base direction for displaying measured waveforms in the recorded measurement data. The recorder is provided with both a cursor-line display switch means for switching from historical trend mode to cursor-line display switch mode for displaying a cursor line for displaying the measurement values of measured waveforms of any hour and date of measurement and a display control means for display, in such a way that the cursor line, time and date at the intersection between the cursor line and measurement waveforms, and the measurement values of the time and data can be distinguished from each other in cursor-line display mode.
