A.4.5.11 Line Form

The Line form () draws a point-to-point line joining up the points making up the data set. Note that for a large and unordered data set this can lead to a big scribble on the screen.

The configuration options are:

Thickness
Line thickness in pixels.
Dash
Dash pattern. The line is solid by default.
Sort Axis
May be used to sort the points before the lines are drawn. By default (option None) the lines are drawn between the points in the sequence in which they appear in the table. But if you set it to X or Y the points will be pre-ordered along the given axis, so the lines will come out looking like a function of the X or Y coordinate rather than a scribble.
Antialiasing
If true, pixels are blurred to give the line a smoother appearance.
