Maybe add 4, 12, and 24 hours or something? There's plenty of screen real estate to make the slider longer without making the detents narrower in pixels.
Ha! In the case writeup, I said "3, 12, 24" but initially thought 4, 12, 24. I changed it to 3.
4 is good.
I do really long trends a lot.
I presume you set the default Historical data set size to 100MB.
Do you use Trend Archive (either Record or Export?). It's helpful whenever you want to trap some "event" with other data values, but don't want to sit there and watch it "live". Just save the archive, then load it, then analyze it (zoom in).
The only issue is that your archive file can get too large to import (yikes!).
The .CSV export can be utilized instead for Excel (not Designer), although Excel can't handle a huge CSV file either - but 64 bit Notepad++ can.
