Ed,
You are currently displaying the NBM
v4.1 dataset which has a single value forecast of 5.3" at the
point you have circled.
If the dataset value offset were kept
at the default of zero, the pie plot would show the number of
NBM components that are above or below the 5.3" value.
Because you added an offset of +1 to
the dataset value (image 2), WSUP is showing the number of NBM
components that are above or below 6.3" (instead of 5.3").
When constant value is selected as the
breakpoint (image 1), WSUP is showing the number of NBM
components that are above or below that constant value (5.0")
at all stations, regardless of what the NBM single-value
forecast is.

Hello,
I had a few Qs on how to interpret the new station pie charts.
1) How do you interpret dataset value?
For example in the image that has a pie chart circled set to
dataset value, the pie chart is depicting slightly over half of
the NBM components/inputs are below the dataset value of
1 for this 24-hr snow accumulation forecast. How
does this pie chart percentage for the dataset value relate
to the distribution and the selected dataset value?
2) For image 2 with the pie chart now set to constant value,
the pie chart is depicting over three-fourths of the NBM
components/inputs are at or above the value of 5", correct?
Thanks,
Ed T
