<br />Scaling variables "XAUPI" and "YAlJPI" indicate values of virtual <br />data units per division. For profile plots, entering "XAUPI" causes <br />the program to take the study reach and divide it into as many plots <br />as are needed to display the profile of the entire study reach in <br />that scale. If "VAUPI" is specified, "XAUPI" must also be specified <br />causing each plot to be scaled to the iridi cated "unitt -per-di vision" <br />scale, or in the default case, "units-per-inch". Any portion of the <br />profile can be plotted on a user defined scale by entering: <br /> <br />(a) "SCALE" followed by one card (or record or line of <br />input) on which val ues must be entered for XMIN, <br />XPI, XMAX, VMIN, VPI, VMAX. Each line of input <br />results in a new graph or window. Any combination <br />of scale variables can be specified. <br /> <br /> <br /> <br />(b) "NSC" followed by anyone or more of the commands <br /> <br /> <br />"XMIN", .XPI", "XMAX", "VMIN", .VPI", "VMAX". <br /> <br />. <br /> <br />(c) Entering in "FORMATTED" user input mode, "SC" cards. <br /> <br />Data output from HEC-2 is ei ther in feet or in meters. I f the <br />user wishes either the "X" data units (cumulative river distance) or <br />the "Y" data units to be converted to some other units. he/she must <br />enter values for variables "XUNIT" and/or "VUNIT". Alpha options <br />recognized by these variables are "FT", "MI", "M", and "KM". If <br />the program does not find one of these options, then it assumes <br />that a numeric denominator has been entered. It determines the <br /> <br />, <br /> <br />30 <br /> <br />.. <br />
