Ask HN: Desktop app for time-series data visualization (automotive)

Hi HN,

Approx 1-2 years ago, there was a Show HN posted that was a desktop application for viewing time-series measurement data, specifically targeted at automotive using the Measurement Data Format (MDF). I had it bookmarked, but unfortunately lost the link in a company-wide nuke of personal browsing profiles on work computers. I've spent a good few hours on HN search and google trying to look for it, without any luck so far. If anyone has the link floating around I'd greatly appreciate it. Other suggestions for similar cross-platform desktop apps welcome.
