XY Files

These are some examples of XY files, which are simply lists of points in the plane. Consecutive points are joined by line segments. Blanks indicate line breaks.

XY files are:

• ASCII
• 2D
• No compression
• 1 image

Reference:

Programs to view an XY file include:

• PLOT_POINTS will read a XY file and create a PostScript file of the points. It can also compute Voronoi diagrams and Delaunay triangulations.

Programs to convert an XY file to another format:

Programs to convert a file to XY format:

Files you may copy:

• dt_10.xy, 10 points; compute the Delaunay triangulation;
• dt_100.xy, 100 points, compute the Delaunay triangulation;
• graham_10.xy, 10 points; compute the convex hull;
• graham_19.xy, 19 points; compute the convex hull;
• grid_49.xy, 49 points in a square grid.
• lsup.xy, 303 points defining the shape of Lake Superior.
• points_100.xy, 100 points;
