This is something I've wanted to do for a while. Turned out to be less work than expected. You can now plot your database. All the Filters still apply so you can plot by time, band, pin type etc. I still need to add an option of letting the Map "View" also act as a filter so you can compare one region to another. You can also set the "resolution" of the bars (you can think of it as frequency tolerence for the chart to decide when to create a "new bar" vs accumulate to an existing one). You can also pinch zoom/scroll etc. This is not released yet or even started on iOS. But it should be available on both platforms soon. Video of how it works. iOS now available It looks like my guesstimate of 0.040 Ghz (+/- 0.020 Ghz) isn't too far off, for a starting point. Note: any statistically calculated to be above the global tolerance, uses the global tolerance (i.e. 0.040 Ghz) so you won't see anything above that. But you can see a "bell curve" centered around 0.25 Ghz You can see the new count of Pins in View in the upper left hand corner.
