A display method and a display apparatus capable of discriminating correctly between a true peak and noise peaks in a waveform data of a fluorescence analysis result that is obtained from an electrophoresis experiment of PCR amplification products of a DNA fragment and also capable of displaying them are provided. Whether or not a complex peak waveform is generated is judged based on sequence information on a DNA marker. When a complex peak waveform is generated, a peak judging algorithm dedicated to complex peak waveform is applied. This peak judging algorithm is characterized in that peak misjudgment can be avoided by making the distance between a first fitting position of a basic waveform and a second fitting position of the basic waveform longer than a unit length at the time of fitting the basic waveform.
