To resize charts together with the window, you need to set height or width of your flash movie in percents. This is done in this line of html:
var so = new SWFObject("amline/amline.swf", "amline", "100%", "400", "8", "#FFFFFF");
This line says that width of your flash width will be equal to 100% of your window (table, div..) and height will be equal to 400 px. if you want your chart to resize together with a window, you have to set:
Note that if your legend, labels, and other objects have fixed X, Y and Width properties, they will not be changed.
