Andrew:

Since you turned the databin into a dataset, I suggest trying the dataset notation:

Dataset[myDataBin][300, All]

Which works for me.

However, I do have one question for you: Why is your databin named "Besso"? Is there any relation to my family?

Have a great and safe week.

Thank you both very much.

Mike, a "besso" is also the Japanese name for a second home in the countryside. A friend who lives in Japan has a besso in the mountains and as you can see, the data is from his weather station. You could probably guess it's in the mountains from the daytime low in late May!

Best wishes,

Andrew
