- ====================
-
- If you have been annoyed by graphs plotted with scale intervals going up in
- threes, or even worse in steps of 0.137, these PROCS/FNs should be useful!
-
-
- Given input data to be plotted, they automatically compute scaling factors
- to fit the data neatly onto the screen with scale steps always in the
- easy-to-read -1-2-5- sequence, and multipliers always powers of 10.The
- program works in any 80-column graphics MODE, and copes with outrageous
- value ranges - like x = 7.002 to x = 7.0023, for example.
-
-
- PROCinit (L.5000) sets up parameters for the current MODE - any 80-column
- graphics Mode.
-
- PROCstep (L.5100) works out the scaling.
-
- PROCaxes (L.5200) draws the axes, scale marks and multipliers.
-
- FNplotx (L.5400) and FNploty (L.5500) take your x,y data values, and return
- x,y coordinates for MOVE, DRAW or PLOT as required.
-
-
- The first part of the program is merely for demonstration.
