If at any time <br />during a user session the Querying and Charting software becomes unresponsive to user input, <br />control can be resumed to the startup dialog by pressing <CTRL > "a ". <br />A detailed description of the information requested, and the data presented, via each available <br />option is given below. <br />Option 1 - o Chart Average River Flow & Average River Gain versus River Mile for Specified Time Interval <br />Option 1 allows a user to graphically view river channel flow and subreach gain versus river mile <br />for a user defined time interval. Upon selecting 'Continue' a dialog box resembling Figure 7 <br />appears on the screen requesting the beginning date and the ending date of the time interval of <br />interest. Maneuvering the cursor from one edit box to another is accomplished by using the <br />mouse pointer to 'click' on the desired edit box. The entered dates must be in the mm/dd/yy <br />format with the 'FROM:' date preceding the TO:' date. If only a single date is desired, enter that <br />date in both the 'FROM:' and the 'TO:' edit boxes. To initiate the querying process and display <br />the corresponding river flow and subreach gain values, depress the 'Query' button. If the dates <br />entered, or the format in which they were entered is unacceptable, an alerting dialog box will <br />appear indicating that the dates must be re- entered. <br />Figure 7 - Option no. 1 dialog box. <br />Upon activating the 'Query' procedure, the appropriate information is retrieved from the <br />databases, manipulated, and then displayed on a chart (x -y plot). Figure 8 depicts a chart <br />generated from option 1 and presents average river flow as circles (left y -axis) and average <br />subreach gain as squares (right y -axis) versus river mile. The river mile range spans from the <br />Kersey gauge (river mile = 0) to the Julesburg gauge (river mile = 153.7). The averaging period <br />(as entered by the user) is displayed in the upper right corner of the chart. For the chart shown <br />in Figure 8 the time window selected corresponds to the first week of June, 1986. Displayed in <br />the lower left -hand portion of the chart are the total number of days requested by the user, <br />followed by the number of days in which data is available in the database(s).
