- I have written an interactive chart program (no name yet) and I am
- looking for beta version testers. Program is checked and more or less
- bug-free, so I am expecting only suggestions for enhancements.
- Program is based upon Gnuplot code, and uses a similar language for
- the user interface. Four parts come directly from Gnuplot: help
- facility, input scanner, doc maker and terminal drivers. Maybe, if
- well tested and approved, program will be a part of Gnuplot in the
- future.
-
- If anyone is interested, I will e-mail him/her the program. If more
- than twenty persons are interested, chart will be posted to
- alt.sources. In any case, there's no full documentation yet.
- Code can be freely redistributed if found useful, as long as
- Copyright messages from Gnuplot and my own are maintained. PLEASE DO
- NOT REDISTRIBUTE MODIFIED CODE, -- rather e-mail me your suggestions.

- ---------------------------------------------
-
- Chart program features:
-
- * Interactive user interface, batch files accepted, on-line help
- * Highly customizable output form (size, [auto]labeling etc.)
- * Four main chart styles :
- - normal side-by-side (adjacent) bars
- - stacked bars
- - layer-over-layer bars
- - pies
- * Many adjustable variations of styles:
- - pie charts with slices exploding in any direction, combining
- slices below specified threshold, drawing clockwise or counter-
- clockwise
- - bar charts with any value for base, drawn in any order with any
- gravity (left, right, top, bottom of page)
- - and lots more
- * Drawing from or across several data files
- * Accepted input:
- - Gnuplot files
- - private format
- - any fixed-field-length (e.g. SAS) files
- * Partial input and missing values supported
- * Internal vector font for better labeling and for terminals that
- cannot rotate text
- * Wide range of supported terminals (well, it's a Gnuplot feature)
-
- Chart faults:
-
- * Gnuplot bugs
- * Only 2D graphics by now (3D bars later ... probably)
- * And, the most important, only one pie chart can be drawn at once. I
- couldn't find the _optimal_ algorithm to fit k pies on the n x m
- screen, for any given k,n,m :-( :-(. Any ideas will be appreciated.
