an imaging unit that captures the cell contained in the sample flowing through the flow cell; a cell image storage unit that stores a cell image captured by the imaging unit; a light source that irradiates the sample flowing through the flow cell with light; a light receiving unit that receives light from the cell irradiated with the light from the light source and outputs a signal corresponding to a light receiving amount; a waveform data storage unit that stores data indicating change in the light receiving amount obtained based on the output signal; a display unit; and a control unit that controls the display unit to display the cell image and a graph representing a waveform of data for the cell in the cell image and/or a marker corresponding to the data. ## Claims ### Claim 1 A cell analyzer comprising: a flow cell through which a sample containing a cell flows;
