line
element objects
One or more lines.
(Edge artifacts)
Minor artifacts at line edges may be caused by the element display's default transparent background. These are usually insignificant. However, if you need to avoid them completely, you can set property backColor = <cds>"opaque"<cds> (okay if there is nothing for the element to occlude).
▸ Object ends on its own?
"Ends on its own" means ends automatically at that point. If an element can end on its own, you don't need to set end conditions for it in property end (unless you want it to maybe end earlier).
No—runs until any condition you set in property end.

points
Default: horizontal line 10 deg long
A 1×4 vector <cd>[x1 y1 x2 y2]<cd> setting line start and end points (deg). + = right/down and positions are relative to element position, which you can set in position (default relative to screen center).
Or if you want to show multiple lines at the same time, use an n×4 matrix with rows corresponding to lines. This is more efficient than using multiple line elements. Lines are also layered front to back in the order you specify them. If you show multiple lines then for each of the properties below you can set one value for all of them, or different values for different lines using a vector or matrix (see property).
width
Default: 0.075 deg
A number setting line width (deg). Or a 1×n vector for different widths for different lines.
color
Default: white
A 1×3 RGB vector with numbers between 0–1. Or an n×3 matrix for different colors for different lines.
Adjustable properties
You can vary or allow the subject to adjust the following properties of an object of this type when it's running. If you need to make other properties adjustable, you can edit the element type code—see Element Type Programming Manual.

PsychBench uses record properties to record information during experiments. You can't set record properties but you can see them in experiment results using input property report.
