Here's an example PI DataLink report that I've used to give folks a jumpstart on what their report could look like. It's not meant to be a complete demo, but rather a quick show of some basic functionality.
The tag-based version is attached as an xlsx and was made with PI DataLink 2014 and Excel 2013. The Excel version matters for those of you on older versions because sparklines became available starting in Excel 2010.
Let me know in the comments below!
Would you be able to share the sample Event Frame data spreadsheet?
