Regression mode line
In the first bracketed field after
LINE1
or
LINE2
, you select the line mode. Select
the REGRESSION secondary softkey to set the regression line mode. For details
about regression calculation range, see “Line Drawing” in Chapter 7.
The pointer moves to second bracketed field as shown:
LINE1: [REGRESSION] LINE ON [Y1] between a point [AT ]
X: [ ]
Y: [ ]
and a point [AT ]
X: [ ]
Y: [ ]
In the second bracketed field, you specify which measurement curve you want to
analyze by selecting the related axis: Y1 or Y2 secondary softkey.
In the third bracketed field, you specify how to select a point:
• Select BY X-Y COORDINATE. "
AT
" is displayed. Then, you enter the desired
X-Y coordinate values or expressions in the
X:
and
Y:
fields.
• Select BY DATA CONDITION. "
WHERE
" is displayed. Then, you enter a
variable name and condition expression to specify a measurement point.
LINE1: [REGRESSION] LINE ON [Y1] between a point [AT ]
X: [0 ]
Y: [0 ]
and a point [WHERE]
[DGM ] = [MAX(DGM)*0.01 ]
[ ]
In addition, you can specify another condition if you position the pointer in the last
bracketed field shown above. Select the AFTER secondary softkey.
AFTER
is
displayed, and you can enter a second variable and condition expression. This sets
up a search start condition for finding specified point. (This setup is optional.)
For example, you can specify the following expressions to search for a measurement
point that satisfies the first condition after the second condition is satisfied.
LINE1: [REGRESSION] LINE ON [Y1] between a point [AT ]
X: [0 ]
Y: [0 ]
and a point [WHERE]
[DGM ] = [MAX(DGM)*0.01 ]
[AFTER] [DGM ] = [MAX(DGM) ]
