The standard value Y-axis formatting form is accessed by RMC on the axis and is shown 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.

Scaling options include use of logarithmic axis, automatic scaling, or user specified max and min for both major and minor tick marks, as shown in Figure 2. Other options include reversing the order of the series (applicable only for the X axis) and showing logarithmic ticks.

Formatting options available are shown in Figure 3. Here the user may set font types, colors, alignment and size for both the title and the labels. Grid line styles and colors for major and minor grid lines may also be set. The number of significant figures may be set in the Label Precision 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:x² + log₂x + log₁₀x, the user should write: x^2 + log_2x + log_{10}x as the label as shown in Figure 5.
