#### A.4.5.33 Lines Form

The Lines form (), available from the XYArray Layer Control, draws a point-to-point line joining all the elements of X, Y array-valued coordinates, resulting in one line for each table row. It is typically used to plot a number of spectra or time series.

Example Lines plot

Lines form configuration panel

The configuration options are:

Shading mode
  See Appendix A.4.6.
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 each array. But if you set it to X or Y the points will be pre-ordered along the given axis, so that lines for unordered arrays will come out looking like a function of the X or Y coordinate rather than a scribble.
