Officially the Beaufort scale is only using integer values. Yet in the grid view it is displayed with a decimal, suggesting it is not. (but no other decimals than .0 are shown).

The graph is also rounded to the integer value, giving it a strange, unexpected look.

I just photoshopped a more informative version which shows more of the expected behavior. I would prefer that. Instead of showing a linear Beaufort scale to the left, it shows a non-linear one and the data in the graph is still linearly scaled (a point twice as high, means twice the speed) No rounding of the data itself is needed.

just a note, there is an empirical formula to convert speed in Beaufort to m/s

v = 0.836 * B^1.5 m/s (0.836 times the value in Beaufort to the power 1.5)

Which gives you the opportunity to display real decimal numbers in the grid view. That or remove the â€ś.0â€ť part in the display. (I would prefer the decimal value)

and another side note: showing the data this way, makes it easy to interpolate and plot.
