1. After plotting data, click Curve.
2. Highlight the name of the curve in the
Available Curves box.
3. Click Graph Selected Curve.
The name of the curve appears in the Graphed
Curve box.
4. Repeat this process until all of the curves you
wanted plotted are listed in the Graphed
Curve box.
5. Click OK.
All curves listed in the Graphed Curve box are
added to the plot, fitting the equation as close
as possible to the data points.
The graph characteristics, such as the type of
scaling on the axes and how far the fitted curve
is extended from the data, are defined in the
Graph Options dialog box.
After fitting the data to a curve, the Data Tab will
display equation parameter values, and fit statistics.
Curve Fit Templates
Curve Fit Templates are listed in the Available
Curves box found in the Add or Remove Curve
window. To access this window, click Curve from
any plot. For more information about using a
template that is already listed, please see “Fitting
Data to a Curve” on page 130.
Creating a New Template
To create a new curve fit template:
1. From the Add or Remove Curve window,
click New.
The Curvefit Template window opens.
2. Enter a name for the template in the Name
textbox.
3. Highlight the Model to be used.
For more information about creating new
models, please see “Defining a New Model” on
page 122.
4. Enter Parameter information under the
Parameters Tab.
5. Select Variable or Constant, in the Type
column, for each parameter.
6. Enter a numerical value, or select a value from
the drop-down menu in the Value column.
7. Enter additional information under the
Advanced Tab.
8. Click OK.
The name or your new template will be listed in
the Available Curves box.
Editing a Template
The edit template interface behaves just like the
new template interface. If you would like to edit a
template:
• From the Add or Remove Curve window,
click Edit.
The Curvefit Template window opens with the
current template settings populating the fields in
the window. See “Creating a New Template” on
page 131 for more details.
Viewing the Plotted Data
The Data Tab found on any plot frame displays the
data plotted along with information about any
curve fits made.
