	The EVAL functions gives the possibility to modify a measurement and plot the result as a separate line. So theoretically one could plot the Dewpoint as a calculated derivative of the Temperature. Also the Growth Degree Days can be simply calculated. The effect of EVAL is that it is not required to transfer data if it can be derived from measurement. Only the measurement needs to be transferred.		The EVAL functions gives the possibility to modify a measurement and plot the result as a separate line.

SUM

@@ Line 23: / Line 23: @@
 The SUM function produces the sum of the Plotvariable from the first of january to the 31 of december after which it resets to zero. So it is a cyclic function!
 When applied to the temperature this leads to the Growing Degree  Days, when applied to rain it leads to the yearly rainfall until the current day. For other variables it may have meaning or it may have not.
 The following example shows the daily average temperature modified to the Growing Degree Days with an offset of 5 °C:

⚫	The EVAL functions gives the possibility to ~~modfy~~ a measurement and plot the result as a separate line. So theoretically one could plot the Dewpoint as a calculated derivative of the Temperature. Also the Growth Degree Days can be simply calculated. The effect of EVAL is that it is not required to transfer data if it can be derived from measurement. Only the measurement needs to be transferred.
