when changes are complete. The graph is displayed with the:
Line fit cursors at the origin or the Y axis
Fit parameters
Cursor coordinates
8. Adjust the cursor locations as follows. Refer to
(on page 6-204) and
(on page 6-205)
Positively specify each cursor location. If the initial location for a cursor (for example, the origin) is
also the final location, inform Clarius by moving the cursor away from that location and then back
again.
9. Drag the fit parameters and cursor coordinates to the locations needed for your project.

Fit # On
Enable or disable Fit #1 or Fit #2.
Type
The type of line fit to apply:
•
Linear:
Chord line of the form y = a + bx, drawn between two graphically
defined data points.
•
Regression:
Regression line of the form y = a + bx for a graphically
defined range of data points.
•
Exponential:
Regression line of the form y = a·ebx for a graphically
defined range of data points.
•
Log:
Regression line of the form y = a + b·log10(x) for a graphically
defined range of data points.
•
Tangent:
Tangent to the plot at a graphically defined data point. The
tangent line has the form y = a + bx.
Axis/Series
The data series for which the fit is to be made. Two cursors will be attached to
the specified data curve.
If the Type is set to Linear, you can also select a Y axis. This results in the
display of free-floating fit cursors that you can position anywhere on the graph.
Fit parameters reflect the scale of the selected Y axis.
Color
The color of the fit line.
Display - Show
Select to display the fit parameters. Clear to hide them.
Display - Precision
The precision of the fit line.
Foreground
The color of the text.
Background
The background color.
Transparent
Select to display the box with a transparent background. Clear to make the
background solid.
Note that selecting Transparent sets the background color selection to light gray.
Display Border
Changes the type of outline around the box. Width must be set to a value other
than 0 in order for the border to be displayed.
Width
