Use this dialog box to approximate signals with parametrical splines.

Open Dialog Box in DIAdem

Settings

X-channel	Specifies the data channel containing the x-values of the signal.
Y-channel	Specifies the data channel containing the y-values of the signal.
Spline type	Specifies the function setup for the spline function.
Weighting factor	Specifies the weighting with which you influence the overshoot behavior for approximating splines.
Create evaluation points	Specifies which method DIAdem uses to generate the interpolation point channel. Depending on which method you choose, specify one of the following parameters:
Partition complete area: Number of partitions	Specifies the number of equidistant sections in the entire x-range.
Partition intervals: Number of partitions	Specifies the number of subsections in each interval of the x-range.
Store result in original channel	Overwrites the values of the input channels. Do not select this setting if you want to use the input channels again.

Result

DIAdem generates two result channels.

To calculate quantity-based in DIAdem, click the Calculate Quantity-Based button on the DIAdem ANALYSIS toolbar. When executing quantity-based calculations, DIAdem checks whether the program can also execute calculations on physical quantities in the same calculation. If DIAdem cannot execute the calculation because the physical quantities are unsuitable, the program displays an error message. Refer to the Help page Calculating Quantity-Based and Non-Quantity-Based in DIAdem for the conditions and rules for quantity-based calculations.
