>>> EDIT Add Devived Channel
This function is used to add a channel to the active dataset. Selecting the Add Derived Channel function displays the Add Derived Channel Dialog Box. Derived channels are calculated from channel data that is already contained in the dataset. For example, we can derive Absolute Humidity from Temperature and . We can derive the equivelent Wind Chill Temperature from Temperature and Wind speed.
You can now List, graph and report on the new derived channel as if it was any ordinary dataset channel
More than one derived channel can be added to a dataset. For example if we are working with a dataset that has Maximum and Minimum Temperature and Relative Humidity we could add Maximum Absolute Humidity, Minimum Absolute Humidity, Maximum and Minimum Dew Point.
