- PRODUCT NAME
-
- JcGraph
-
-
- BRIEF DESCRIPTION
-
- A graph program. Create 2D and 3D graphs from ASCII data files.
-
- This program was provided on the coverdisk of Amiga Computing
- Magazine, issue 71, March 1994. See my review of this magazine elsewhere
- in the comp.sys.amiga.reviews archives.

-
- LIST PRICE

- Freeware.
-
-
- SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
-
- HARDWARE
-
- 1MB RAM required.
-
- SOFTWARE
-
- Workbench 1.3.
- ARexx recommended for serious use.
-
-
- COPY PROTECTION
-
- None.
-
-
- MACHINE USED FOR TESTING
-
- Amiga 500, 1MB Chip RAM, 2MB Fast RAM.
- Kickstart 1.2, Workbench 1.3, ARP.
- Fujitsu 100MB SCSI drive in A590.
-
-
- INSTALLATION
-
- Drag the JcGraph drawer to your hard disk. On a Workbench 1.3
- machine, you should copy the libs/kd_freq.library to the LIBS: directory.
- "JCGRAPH:" should be assigned to the program's drawer (in the
- startup-sequence file, for example).
-
-
- REVIEW
-
- This program gives the ability to display graphs in 2D or 3D. Graphs
- are read from an ASCII file, whose format is described in the documentation.
- There are 13 2D graph types and 13 3D graph types to select from. It is
- possible to rotate the graphs in three dimensions (even the 2D ones).
-
- The program opens three windows on the Workbench. One is the Control
- Window, which includes sliders for 3D rotation, 10 buttons which can be
- assigned ARexx scripts, and 'undo' and 'render' buttons. The two other
- windows are the Preview Window, which is a wireframe display of the current
- graph type and 3D placement, but displays a generic graph (not the one you
- loaded); and the Rendering Window, which displays the rendered results in
- filled 3D (or 2D). All the windows can be dragged, and the Preview and
- Render windows can also be resized.
-
- Selecting the graph type is done via a file requester, which is
- a custom one on Workbench 1.3 machines. New graph types may be designed in
- the form of ASCII files.
-
- The resulting graph can be saved in several formats: IFF, EPS,
- Aegis Draw, and Geo 3D.
-
-
- DOCUMENTATION
-
- There's a tutorial in the magazine, and a documentation file on the
- disk, which also includes a tutorial. The tutorials explain basic operations
- of the program well, but there are no examples for the programming aspects
- of the program (ARexx and graph type construction).
-
-
- LIKES AND DISLIKES
-
- LIKES
-
- The preview window.
- ARexx interface.
- Custom graph types.
- Support for many output formats.
-
- DISLIKES
-
- Selecting a graph type is awkward. If there's anything a user would
- want to do with this program, it is trying out different graph styles, to
- select the most effective for the data in question. Having to load a type
- from the file requester every time is slow and uncomfortable, especially if
- you happen to work from diskette.
-
- Window updates are very slow.
-
- The pie chart doesn't look anything like a pie.
-
- The hypertext system is uncomfortable. I don't like having a window
- for every page open, and I'd rather single-click than double-click to select.
- (But that's just me. I wonder how AmigaGuide does it.)
-
- [MODERATOR'S NOTE: AmigaGuide uses a single click. - Dan]
-
- How about the ability to load spreadsheet data into the program?
- Could make it more useful.
-
- Too many windows clutter the Workbench (see BUGS).
-
-
- COMPARISON TO OTHER SIMILAR PRODUCTS
-
- This program is said to be unique on the Amiga. I've never used such
- a program seriously on another platform, but I have dabbled with a similar PC
- program which was much easier to use: it had a spreadsheet-like front end
- for data entry, if I remember correctly.
-
-
- BUGS
-
- Tooltype SCREEN=custom doesn't work. The program still opened on the
- Workbench screen.
-
- Context sensitive help often gets the wrong context.
-
- The Arrange option, which should organise windows logically, uses
- what seems to be the first 200 lines of my PAL Workbench, and results in a
- messy screen.
-
-
- VENDOR SUPPORT
-
- This was once a shareware program, but not enough people registered,
- so it's now freeware and there's no support.
-
-
- WARRANTY
-
- Coverdisk replacement by the magazine.
-
-
- CONCLUSIONS
-
- This is a programmer's application. A user with no knowledge of
- programming, or one who doesn't want to dabble with the arcane features of
- this program, is left with a program which is not very friendly, nor very
- powerful.
-
- Someone who needs such an application, and is willing to invest time
- learning how to customise it (i.e., to learn ARexx and experiment) could
- possibly have a very useful program on his/her hands. The ARexx interface
- could allow the creation of a more powerful and friendlier front end.
-
- The slow windows update and awkward use, and having to work on a 4
- colour Workbench (on my 1.3 machine) give a bad impression. Still, it's
- possible that with a faster machine and a newer Workbench the program would
- be more usable.
-
- I'll give this product 7 out of 10, simply because I believe that in
- some circumstances, on some machines, and for some people, it could prove
- useful, even very useful. For me and my machine, 5 out of 10 would be more
- suitable.
