The standard value Y-axis formatting form is accessed by RMC on the axis and is shown in in Figure 1 and Figure 2. The use of these forms is intuitive. Axis labels may be entered in the Main Label box, however the formatting for the label is set in the Formatting tab. The user may specify the color and thickness of the Y axis line by pressing the Line Properties box in the Axis Display Characteristics frame.

The axis labeling method for the X axis is the same as that for the Y axis when using Julian dates. However, when a Gregorian date format is used on the X axis an alternative date axis form is provided as shown in Figure 4. Most of the options in this form are intuitive. However, one shortcut to selecting a calendar year is to enter the year number (e.g. 2003) in either the min or max field and then hit enter or tab and the dates will be set, along with appropriate tick marks.

Subscript and Superscript in Graph Legends
The Time Series Grapher and EFDC Profile tools have been updated to display user defined subscripts and superscripts in the legends. This is done using two underscore key strokes ("_") and a single caret (" ^ ") for subscripts and superscripts respectively. An example of implementing subscripts and superscripts is shown in Figure 9 10. If several characters are part of a group they should be placed in curly brackets ("{ }"). For example to display:x
...
2 + log2x + log10x, the user should write: x^2 + log_2x + log_{10}x as the label as shown in Figure 5.
