<br />. <br /> <br />The variable-vs-variable graphics routine does not restrict the user <br />to only a certain number of time periods, but the user should be aware <br />that the arrays that contain the curves' coordinate values are limited <br />to a total of no more than four hundred values. For example; if a run is <br />made that uses one hundred time periods, then no more than four curves can <br />be plotted at a time. If a histogram is requested, then the output is <br />restricted to a maximum number of two hundred time periods. A histogram <br />plot requires two times as many points as there are time periods on <br />tape 95. <br />The user is also required to provide the proper curve labels when <br />using HEC-6 or GEDA input data, since the default curve labels are for <br />HEC-2 data. The user must provide labels for curve numbers two, three, <br />and four of the cross section plotting routine. <br />Curve number two is used to plot the moveable bed limits and elevation <br />of moveable bed (EMB). Curve number three is used to plot the dredge <br />channel limits, elevation of bottom of dredge channel (EDC), and the <br />depth of over dredging (000). Curve number four is used to plot the <br />moveable bed with time, when tape 95 has been provided. If no new <br />labels are provided by the user, the HEC-2 labels will be used for curves <br />two, three, and four. It is assumed that the user is familiar with the <br />Stream Hydraulics Graphics Package users manual and knows how to provide <br />the general commands to effect the change in curve labels. See Appendices <br />I and II for examples. <br /> <br />. <br /> <br />3 <br />
