Thanks for the screenshot and explanation. I am presuming you run several samples so you want a report which separates the info by sample/injection? I tested some data I have with several derived channels, and I got this to work fine. It will be the same regardless if its an instrument channel, like your DAD or pressure/pump examples, or like mine with several derived channels (pressure and single wavelengths), the same procedure applies.
So in Empower 3, create a new Summary By All report, preferably Landscape to give your chromatograms more room. Add "Auto Scaled with Legend" from the Chromatograms tree on left of report publisher. Edit the Legend to add "Channel name", take out the channel type already there. Channel Name will be the name of each individual channel. Add or remove fields in the legend as you need. Under the "Order by" tab, pick first Channel Name ascending, followed by Channel ID ascending. No other changes are needed.
Next, add in a peak table, making sure to add Channel Name as a field in the first tab so you can see what peaks are derived from what channel, place the peak table group just under your chromatogram with legend group, and order the table by Date Acquired ascending, followed by Retention Time ascending. No need to group by anything. You may need different info in this table such as custom field results, amount, Height etc- add whatever you need. In order to associate all the chromatograms of your channels with all the peaks in those channels, you need to group them and make a composite order. To group select both the chromatogram and table, Edit<Group. Then right click to access Composite Properties- in the Order by Tab here, select first Injection ascending then Samplename ascending. You may want to add something in the Data Filtering here, such as SampleType = Unknown or maybe you only want samples with the label U... considered so could be Label = U*. Whatever suits your needs. Then when you select some processed results and preview using this report, you get the chromatogram of each channel in that sample, displayed one after the other, followed by a table of all the peaks in all those channels in that sample, then another set of chromatograms and peaks for the next injection, etc.
Be aware though that you have a lot of channels to show so its probable that the graphics will spill over 1-2 or more pages, so you might want to add in a page break under your peak table before you do the composite grouping. This will at least make the report look a bit cleaner when you are reporting from one sample to the next. You can always resize the chromatogram with legend group beforehand to test it out to your satisfaction.
Hope this helps.
