Yoix / YDAT Information from the Yoix README File

        We're now distributing YDAT (Yoix Data Analysis Tool), which
        is a collection of scripts and Java class files that can be
        used to display and analyze data. Class files needed to run
        YDAT applications are now included in the yoix.jar file that
        can be downloaded from our web site or installed using the
        Yoix installer. When you run the demos remember that they're
        interactive, so try things, like holding a mouse button down
        as you move the pointer around in a histogram or graph (the
        the behavior of mouse buttons in a graph is controlled by the
        JChoice that appears in the lower right corner). If you see
        a horizontal or vertical axis press button 1 when the pointer
        is in the narrow light-gray region (the axis slider) and move
        the pointer. Press button 2 in that region you can drag the
        entire slider while you're hold the button down.

        When you run the installer you get a generic script named ydat,
        several other scripts that run canned YDAT demos, and another
        one named ydot that can be used with AT&T's graphviz software
        to display and manipulate graphs that have been formatted in
        the xdot output language (i.e., you used the -Txdot option

        YDAT uses config files to describe the data that its supposed
        to display, and right now the config file for graphviz xdot
        output is the only generally useful one that comes with this
        release. The situation should improve in the near future and
        we hope to provide more YDAT documentation and info about the
        config files that should let you customize YDAT and display
        your own data. In practice it's not all that difficult and a
        custom config file can often be built and tested in several
        hours, however without any documentation it would be a rather
        difficult task.

        One final note - the YDAT related Yoix scripts end up in the
        directory named ydat/scripts after you run the installer and
        the scripts that run YDAT point at ydat/scripts/ydat.yx. The
        entire ydat/scripts directory can be moved to a web server if
        you want and the definition of HOME in ydat.yx is the only
        thing you have to change when the files are moves to the web
        server. Point the various ydat scripts in the bin directory at
        the ydat.yx script on the server and YDAT will no longer be
        using the locally installed Yoix scripts.
