XY is a viewer of graphs, especialy suitable for large data sets (for example model output) and maps.

The program can easily be implemented in user-interfaces. In that case the layout of the graphics is determined by the developer of the user-interface.

The functionality for the user is then limited to:

•	creating output

•	zooming in and out (if one graph is shown)

•	statistics (if a gridmap is shown)


Creating output

You can print your graph, create a postscript file or create an enhanced metafile.


Printing
Print the graph.

The graph can be printed to any windows-compatible printer with File/Print (shortcut Ctrl-P).

The graph will be printed on the default xy printer, which is the printer last used by xy.

Before printing you can set the paper-orientation.

If you have a monochrome printer the 'Grey scale' checkbox should be flagged. XY will then create optimum gray scales for better output.

The 'Open Print Setup' checkbox will result in XY showing a 'Page Setup Dialog' box in which you can change page-settings.

With the 'Choose Printer' button, you can choose another printer than displayed at the top of the dialogbox.


Postscript
Create a Postscript File.

You can create a postscript-file with File/Create Postscript File (shortcut F5).

You can choose paper-orientation and check for printing in color.

If you want to print your postscript file to a monochrome printer, uncheck the 'Print in Color' checkbox. Then XY will create optimum gray scales for better output.


Enhanced MetaFile
Create an Enhanced Meta File.

You can create an Enhanced Meta File (emf) with File/Create Enhanced MetaFile (shortcut F6).

An Enhanced MetaFile can easily be imported by Microsoft Word 97 or higher and many other Windows programs. It's  high quality output, because it is a vector-format.

You can choose three different orientations of the graph.

If you have a monochrome printer the 'Grey scale' checkbox should be flagged. Then XY will create optimum gray scales for better output.

The resolution setting affects the precision of the data output and the thickness of the lines.


Zooming

You can zoom in within a graph or map with the left mouse button.

Zoom out to the original size with Edit/Zoomout (shortcut F8).


Statistics

When a gridmap is drawn, you can view the frequency distribution of the map. With Statistics/Map class distribution (shortcut F3) a distribution is shown in a graph of the choosen classes of the map. A cumulative distribution is show with Statistics/Cumulative distribution (shortcut F4).

With Statistics/Map info the outer filled gridcells are shown. You can choose to zoom in to that coordinates.
