Peaks not shown on the online plot

I am running 1100 Agilent HPLC with DAD. During the run I can not see any peaks, just a straight line, but after the sample is over the report is coming with the peaks. I want to watch the peaks while they are generated. Thanks

I'm assuming you're using Chemstation software. First, ensure you have the correct channel selected to display (click the three-arrow icon in the corner to show the online plot in a separate window, then click on "Change"). If the displayed channel is your analysis wavelength, make sure your y-axis scale matches what's on the reports.
