We have data points that are collected at 5 minute intervals. How do I make the trend cursor snap to the actual data point?

If you mean the trend cursor in PI-Vision, I am also wondering this.
Yes, I mean the trend cursor in PiVision.
I don't think any of the built-in visualizations have snapping, so if you want that you could see if anyone sells custom symbols having this functionality. (Or develop it yourself).
An alternative to snapping could be to enable stepping for the data point, this will at least provide you a visual trend where the value is kept until the next one occurs - meaning there's no interpolation between the actual data events. I'm guessing you're interested in the actual data events written to the archive, not the line between them.
Stepping can be enabled directly at the PI tag, using PI System Management Tools or the PI Builder add-in to Excel.
