Skeleton Plotting Absent and False Rings

How to mark ring-growth anomalies on a skeleton plot:

Missing Ring:
- Sample at left didn't have a ring for year 1905 of the chronology (index value of 0.0)
- A dashed mark is drawn on the skeleton plot between the 19th and 20th lines
- Try This: Move skeleton plot one position to the right
False Ring
- Sample at right had a false ring for year 1925 of the chronology (index value of 2.0)
- Diagonal marks are drawn on the skeleton plot on the 39th line
- Try This: Move skeleton plot one position to the left

When you try skeleton plotting for yourself, you can turn on or off ring-growth anomalies:

There will be check boxes for absent or false rings, as on the right
- Check one or both options to allow these growth anomalies
- Un-Check the options to disallow these growth anomalies
- Mouse click the "Restart a new core" button
Important point #1: With options checked:
- Ring-growth anomalies are only possible, not for certain (just like in real life!)
- Mouse click the "Hint" button to learn if your new core has ring-growth anomalies
- Mouse click the "Hint" button again to hide the hint
Important point #2:
- When there are absent/false rings, include their dates when you find the dates
