The AWT package provides subprograms for creating graphics. With it you can draw points, lines, circles, arcs, squares, pies, and quadrilaterals. There are also three subprograms that draw a pie chart, bar chart, and line graph simply by passing a select statement.
Although loosely patterned after the Java awt package, Java is not required to use this package. Graphic "images" created by this package are rendered in real-time. Depending on your broswer, you may actually see the image being drawn.
All images are created relative to the origin (0,0). By default this is the upper-left and upper-right area of your browser's window. You may change the origin with two global variables in this package: X_ORIGIN and Y_ORIGIN. It's always a good idea to reset them to zero when you are done.
AWT defines the following constants:
ALICEBLUE constant varchar(6) := 'F0F8FF'; ANTIQUEWHITE constant varchar(6) := 'FAEBD7'; AQUA constant varchar(6) := '00FFFF'; AQUAMARINE constant varchar(6) := '7FFFD4'; AZURE constant varchar(6) := 'F0FFFF';

This subprogram creates a bar chart from your select (value) statement. Your select statement should return two columns that correspond to the Y axis (its label) and the X axis (its value). It is up to you to specify the appropriate ORDER BY and GROUP BY clause.
If all labels can be centered at the bottom of the screen, they will be centered at the bottom of the screen. If this is not possible, your labels are displayed vertically if their length is less than four characters or you specified force_label to be true. In any case, a mouseOver on each bar will display its label and value.

drawLayer creates a layer or div object (depending upon the browser that invoked it) and is thus compatible with Netscape 4.X browers and Netscape 7.X browsers. Most of the subprograms in this package actually call drawLayer.
onMouseOver, onMouseOut, onMouseDown, and onMouseMove are JavaScript events that may have to be supplied by JavaScript functions that you write; for example, onMouseOver may change the backGround color of a layer while onMouseOut restores the background color of that layer. It is beyond the scope of this manual to actually explain how you do that. HTTP.SP_HTML_CALENDAR is just one example that you might want to reference since it handles all of these events.

This subprogram creates a pie chart from your select (value) statement. Your select statement should return two columns that correspond to the Y axis (its label) and the X axis (its value). It is up to you to specify the appropriate ORDER BY and GROUP BY clause.
Since it is difficult (or unpleasant) to display more than a few pieces of pie, you may specify a threshold for those values that should be grouped in the other category. Normally, pie charts display their values in descending order. Without the appropriate ORDER BY clause, your pie chart may group the wrong information under other.
