-
- [Select Plot]: This is the entry
- point for plotting functions.
-
- <ACCEPT><ENTER> to view Family
- Menu selections.
-
- Note: Select the Run Macro
- option for a demonstration of
- XYSee's many exciting features.
- 2 11 [Puzzle Menu]: Puzzles are
- combinations of functions
- interwoven on a common display.
- The challenge is to select
- pieces (functions) with
- dimensions (variable values)
- matching the display within a
- user defined tolerance.
-
- <ACCEPT> to view Puzzle Menu
- selections.
- 3 12 [Run Macro]: Macros are disk
- files containing commands which
- emulate manual keyboard se-
- quences. Macros can replace
- small, frequently used routines
- or automate large and complex
- presentations ("Tutorial").

- your macros ("Edit Files").
-
- <ACCEPT> to view Macro Menu
- Selections.
- 4 10 [Edit Files]: Create, change,

- beautiful! Each sketch is based
- upon a particular family of
- functions.
-
- <ACCEPT> to view the different
- sketches.
- 8 11 [Update Values]: Plot displays
- are defined by values assigned
- to formula variables. The
- assigned values typically

- function. You may investigate
- the effect of variable changes
- with this option.
-
- <ACCEPT> to change variables.
- 9 7 [Cursor]: Use this visual
- indicator to identify points

- vidual plots of different func-
- tions may be combined at will.
-
- <ACCEPT> to view Overlay menu
- selections.
- 11 11 [Statistics]: Each function has
- associated with it various sta-
- tistics. XYSee attempts to
- calculate as many of these as
- possible. In some cases, ter-
- minology has been selected to
- introduce common engineering
- usage (amplitude, frequency,
- offset, etc.).
-
- <ACCEPT> to view statistics.

- model entry box.
- 13 11 [Print Plot]: The current
- plot display may be copied to

- need to change the display
- scale.
-
- <ACCEPT> to open a zoom scale
- entry box.
- 19 9 [Show Outlier]: This feature
- highlights out-of-tolerance
- values which can cause a so-
- lution attempt to fail. "Show

- correct values while attempting
- to "zero-in" on incorrect ones.
-
- <ACCEPT> to highlight outliers.
- 20 12 [Select Macro]: Macros are disk

-
- <ACCEPT> to open a color set
- entry box.
- 26 10 [Files in]: XYSee normally
