3.7.5.33 Layer.Axis.ReflineLayer-Axis-Refline-obj
The reference line object is a sub-object of the layer axis object. And axis is a sub-object of
layer object. You can use range notation to define a layer object:
- range layerObject = [pageName]layerName!
And then access the axis object by:
- layerObject.Axis.refline#.property
Where Axis is the axis specification: x is the bottom X axis, x2 is the top X axis, y is the left Y axis, y2 is the right Y axis, # refers to the index of the reference line.
Also refer to the object: layer.axis.reflines object
Required Version: Origin 2018 SR1
Properties
Note: axis is a placeholder for x, y, x2, or y2.

Description
|
| layer.axis.refline#.TYPE
|
Read/write
numeric
|
Specify to add the reference line at Axis Begin or Axis End: 1 = Axis Begin, 2 = Axis End.
Please note, this control is totally different from the Value Type drop-down list on the Reference Lines dialog which is used to specify the Value Type for the custom reference lines (excluding Axis Begin and Axis End).
|
| layer.axis.refline#.VALUE
|
Read/write
numeric
|
Specify the position value or formula/function of refline#.
- Entering a value will add a vertical/horizontal straight line at the axis position.
- Entering a expression/function string will add a arbitrary straight line on current layer. See the second example below.
You can refer to the At Axis Value control in the Reference Lines dialog to learn the details of how to enter the value or string.
|
| layer.axis.refline#.LINESHOW
|
Read/write
numeric
|
Whether to show refline#: 0 = hide, 1 = show.
|
| layer.axis.refline#.LINEAUTO
|
Read/write
numeric
|
Use auto format for refline# (follow the format of major grid lines). Set to 0 to disable auto formatting.
|
| layer.axis.refline#.LINECOLOR
|
Read/write
numeric
|
Specify the line color for refline#. The color function can be used, as in:
layer.x.refline1.LINECOLOR = color(blue);
layer.x.refline2.LINECOLOR = color(240,208,0);
|
| layer.axis.refline#.LINESTYLE
|
Read/write
numeric
|
Specify the line type for refline#.
|
| layer.axis.refline#.LINETHICKNESS
|
Read/write
numeric
|
Specify the line thickness in pts for refline#
|
| layer.axis.refline#.FILLTONEXT
|
Read/write
numeric
|
Specify the index number of reference line to which the area will be filled from the current refline#. Set to 0 to turn off fill pattern
|
| layer.axis.refline#.FILLCOLOR
|
Read/write
numeric
|
Customize the fill color. The color function can be used, as in:
layer.x.refline1.FILLCOLOR = color(Origin);.
layer.x.refline2.LINECOLOR = color(255,0,128);.
|
| layer.axis.refline#.FILLTRANS
|
Read/write
numeric
|
Customize the fill color transparency in percentage.
|
| layer.axis.refline#.labelshow
|
Read/write
numeric
|
Wheter to show label for refline#: 0 = do not show label, 1 = show label.
|
| layer.axis.refline#.labelpos
|
Read/write
numeric
|
Specify the label position: 0 = bottom, 1 = top, 4 = middle.
|
| layer.axis.refline#.labeltext$
|
Read/write
string
|
Specify the text to be shown as label for refline#. The default setting is <value as entered>, which means showing the position value as labeh.
|
Example
Example 1
The following scripts create a graph window, and then add two straight reference lines on X axis and customize reference lines.
win -t p; //create a graph window
layer.x.reflines.count = 2;
layer.x.refline1.TYPE = 1;
layer.x.refline2.value = 4; //add a reference line at x = 4
layer.x.reflines.lineshow = 1;
layer.x.refline2.labelshow = 1;
layer.x.refline2.FILLTONEXT=1;
layer.x.refline1.FILLCOLOR=3;
layer.x.refline1.FILLTRANS=50;
Example 2
The script lines below create a graph window, and add two arbitrary straight reference lines, one with a LabTalk expression and another with a statistical function.
//new a worksheet, fill the two column with row number.
plotxy (1,2); //create a graph window with the data
layer.y.reflines.count = 2;
layer.y.refline1.value$ = "15-x"; //specify a expression to add a reference line Y=15-x
layer.y.refline2.value$ = "Mean(plotdata(*, Y))"; //add a mean line at Y axis
layer.y.reflines.lineshow = 1;
layer.y.refline2.linecolor = color(blue);
layer.y.refline2.labelshow = 1;
