Drawing a line in LC7

[Terence Heaford]

LC need to change the documentation.

  Tip:  When setting the points property, you can separate the individual points with a comma instead of a return. The points property is always reported with the points on separate lines, however.


Makes life rather challenging & irritating.

Thanks for your help.


All the best

Terry
