12.6. Area
The
Area
tool is used to determine an area between the displayed graph, the horizontal
axis and two boundary lines.
To determine an area
•
Select
Process/Analyze > Area
.
•
In the top left drop-down list select the
graph from which you want to
determine an area.
•
The diagram shows two boundary lines
between which the area is calculated.
Drag the boundary lines to the required
position, or type the x-values for the
boundary lines in the

12.7. Function Fit
The
Function fit
tool is a procedure to approximate the data in the graph with a
standard mathematical function. You can choose from a large number of function types.
The coefficients of the fit function are determined using a least-squares method. Fitting
can be done manually or automatically.
To determine a function fit
•
Select
Process/Analyze > Function Fit
.
•
In the top left drop-down list select the
quantity which data you want to fit.
