- AXIS LEGENDS
-
- By default, Graphmatica labels the hatch marks across the graph with the
- number of their coordinate so that you can more easily locate points or find
- the coordinates of a graphed point. In some cases, though, especially when
- doing graphs near the axes, the numbers can be confusing and you may want to
- turn them off. To do this, select the Legends option in the Labels menu. In
- the choice box, select the None button.
-
- If you find that the interval that is automatically chosen for the grid
- spacing is not well-suited to your task, select the Custom spacing button and
- you will be prompted for the increments you prefer for the X and Y axes. Next,
- you can choose between two behaviors when the grid size changes: 1) Lock the
- legend spacing to the values you selected, or 2) Scale the grid spacing along
- with the grid itself. Unfortunately, neither option will be likely to satisfy
- you if you change the grid spacing by a non-integer factor or by too much, so
- you may have to reset the spacing to more suitable increments again manually.
-
- To go back to the default behavior, select the Automatic spacing button in the
- Axis Legends dialog.

- ADDING TITLES TO YOUR GRAPHS
-
- To add a title line and/or labels along the sides to your graph, select Titles
- from the Labels menu. You can type in a new title, edit one you typed in
- previously, or delete the title by pressing enter on the blank line. For the
- y-axis labels, the length of the string you can use depends on the number of
- rows you monitor has: CGA and EGA can hold 23 letters and VGA can hold 28. The
- program presents you with the previous label which you can edit, discard by
- pressing ESC and typing a new string, or turn off completely by pressing ESC.
-
- When you print (or Print Preview), the title is written across the top of the
- screen, and it is automatically centered (don't try to center the title
- manually). When you are graphing and the menu is active, the title line is not
- shown. Like the title, the y-axis labels are automatically centered
- (vertically) on the graph. Graphmatica does not draw these labels until you
- print or print Preview, since they are intended mainly to enhance printing.

- Press PgDn for help on Annotations.
- ANNOTATIONS
- Annotations are short text phrases which you can place anywhere on the grid to
- label important points on your graphs. Graphmatica maintains a list of up to
- ten 30-character annotations. To add an annotation to the graph, select
- Annotate from the Labels menu. Type in the text you wish to use and press
- enter. Now a crosshair cursor will appear. Move it with the keyboard or mouse
- to the position where you want the upper-left corner of the text. Then click
- the left button or press enter to paste it down. The text will appear on the
- screen immediately. Remember that it is associated with a logical x,y
- coordinate on the grid, not with the physical point you clicked on or with any
- particular equation. Also note that annotations that would run off the screen
- cannot be drawn. You must zoom out so they are fully on the screen before they
- will appear.
-
- To edit a previously entered annotation, select the Edit Annote menu item from
- the Labels menu. Next choose the annotation to edit from the listbox. You can
- then choose the delete the annotation, change its text, or change its
- position. Pressing Esc at this prompt instead leaves the annotation unchanged.
- All of the annotations you have entered will be saved with any equation list
- you save, and will automatically be displayed again when you reload it. Like
- the graph title, the current annotations are cleared before loading a new file
- and when you Clear all of the equations from the redraw queue.
