- !GraphDraw, © Chris Johnson, 1990 - 1995
-
- What this software does
- =======================
-
- It allows the entry of the x and y values for a number of
- data, and the data may then be fit to
-
- • best straight line
- • best parabola
- • a cubic spline curve
- • a polynomial of order up to 6
-
- The resulting graphs may be saved as a !Draw file, or
- printed via any standard RISC-OS printer driver.
-
- Use of !GraphDraw
- =================
-
- Running the application
- -----------------------
-
- This software is fully RISC-OS compatible, and is
- multi-tasking. It can be run from the desktop in all the
- standard ways.
-
- Double clicking on the !GraphDraw icon in a directory viewer
- will install its icon on the icon bar.
-
- Clicking SELECT on the iconbar icon will open an empty edit
- window, into which the pairs of x,y data may be entered.
- Full scrolling and editing facilities are available during
- data entry.
-
- The application can also be started by double clicking on a
- data file of !GraphDraw format. In this case, besides the
- icon appearing on the icon bar, the edit window will be
- opened with the contents of the data file displayed, for
- further editing if necessary. A data file may also be
- dragged, either into the edit window, or to the iconbar
- icon. The data will be loaded, overwriting any data that had
- previously been entered.
-
- Full interactive help is available, via !Help or
- !BubbleHelp, and additional explanation is available from
- several of the application menus.
