Functions - Fourier MultiLogPRO User Manual

4. Functions

1. Select a function from the Functions list. MultiLab displays the
function's formula at the bottom of the dialog box.
2. If you use the cursor to select a data set, it will be highlighted in the
G1 drop list, but you have the option of selecting a different data set.
Tip: To create a function whose independent variable is time (e.g. to fit a
mathematical function to a data series), select a time series from the G1 drop list. If
there are several plots on the graph the list includes a separate time series for each
plot as the number of data point may vary from plot to plot.
3. If the analysis function involves two data sets, select the second
data or time series set from the G2 drop list.
4. To synchronize the Y – Scale with one of the plots on the graph,
check the Synchronize scale with checkbox and select the
appropriate plot from the adjacent drop list.
5. Enter a constant in each of the A, B and C boxes (optional, the
default values are one for a coefficient and zero for a free term).
6. Enter a name in the Name box (optional – the default name includes
both the function's formula and the data set name).
7. Enter a unit (optional).
8. Select an Open option.
9. Click OK.
