The Derived Preferences give access to some powerful nonlinear mappings. The Derived Preferences section defines those mappings, but there are some ways of using those mappings that are not immediately recognizable. This section gives some ideas regarding such usage.
Plotting The Same Channel
To plot the same channel on a graph select the same index in the Channel Index column for two different channels. For example, to see the raw and curve fit results of channel one, in channel row 2 select Derived Type Average, Channel Index 1, Average Type of MF-Fit, length of 20 (for example) and click Apply. Channel 2 will be the remapped channel one.
Derived Channel Alters Data
When you use a derived channel it maps the source data which means any data saved with DAQ Plot is derived data, not the raw voltage signals.
Composite Mapping
Derived mappings are applied one channel after another beginning with the lowest channel number (1). Thus you can build composite mappings. For example, if you data is in channel one then for channel two, use a Channel Index mapping of 1 and for Channel three use a Channel Index of 2. Then Channel three will be the twice mapped result of channel one. For a thorough example of a composite mapping see Windowed Integration.
