Each option is described as follows:

*Minimum TSD (Y) Axis Value. *This is the y-axis minimum value. Enter a value

less than or equal to the default value. The default value is the minimum value of the

data.

*Maximum TSD (Y) Axis Value. *This is the y-axis maximum value. Enter a value

greater than or equal to the default value. The default value is the maximum value of

the data.

*Axis Increment. *This is the y-axis labeled tic marks. This number must be

evenly divisible into the difference of the maximum and minimum values.

*TSD (Y) Axis Title. *This is the y-axis title. This title will be parallel with the y-

axis and approximately centered vertically to the left of the y-axis.

*Minimum Date (X) Value. *This is the x-axis minimum value. It is a date and

must be in the format of four digits for the year, two digits for the month, two digits

for the day, a space and four digits for the time (e.g., yyyymmdd hhmm). The time

must be in military time. An example would be. 19980730 1300.

*Maximum Date (X) Value. *This is the x-axis maximum value. It is a date and

must also follow the format listed above.

*Labeled Date Increment. *This is the x-axis labeled tic marks. This number must

be evenly divisible into the difference of the maximum and minimum dates. It must

be in the four-digit military time.

*Unlabeled Date Tic Increment. *This is for unlabeled x-axis tic marks. This

allows additional tics to be placed in the x-axis without placing text with the tics.

This number must be the same criteria as the labeled date increment.

*Date (X) Axis Title. *This is the x-axis title. This title will be parallel with the x-

axis and approximately centered below the x-axis.

After entering the desired parameters, click *OK. *If the minimum, maximum, and

increment values do not meet the specified criteria, a second menu for these

parameters will be displayed for the user to re-enter. These data are organized and

plotted in the *Time Series Data *view, but are not displayed. A menu is displayed

asking *Plot Data Now*? To analyze another time series data file, choose *No *and start

over. To see the results, choose *Yes. *The data plotted in the *Time Series Data*

view are displayed (Figures 5-13 and 5-14), and the user is prompted whether to

export the data. Choose *Yes *and enter a file name to export the data.
