Patching missing valuesGaps of up to three missing values can be patched with the PATCH button: the values inserted are either based on linear interpolation, or, in the case of wind direction, simplex extrapolation of the last legal value.
A small dialog (pop-up)wind reports on the number of succesful or failed patch attempts. Patched values are marked and shown in GREY in the time series display.
To drop all patched value, a reset button can be used. All patched values will again be replaced by a missing value code (-9999).
