- /****************** CPlot 1.0, © 1990 by Terry W. Gintz ***************/
-
- CPlot graphs linear functions in two dimensions, similiar to a Mandelbrot
- plot. You start with a linear function like 10sin(x²+y²) and CPlot treats
- each point on the screen as an X-Y coordinate, color-scaling it according
- to its magnitude for a preset range of inputs.
-
- About the menus and windows:
-
- The Project Menu--
-
- 'New Plot' -- zoom in or out on a particular area of x-y coordinates.
- 'New Formula' -- opens the New Function window for setting plot
- parameters and formulas.
- 'Continue Draw' -- continue a plot if you stopped it before it finished.
- 'Save Function' -- save current plot paramters and save screen in IFF
- format.
- 'Load Function' -- load function previously saved by CPlot.
- 'Quit' -- exit CPlot.
-
- The Resolution Menu--
-
- '320X200' -- lo-res mode.
- '640X400' -- hi-res mode.
-
- The Main window:
-
- All drawing and zooming appears here. Use the mouse to select corners of
- the area you want to zoom into or out of.
-
- The New Function window:
-
- F(Z) -- The main function that will be graphed.
- F(X) and F(Y) -- optional parametric functions which are averaged
- together and graphed as a single function. You need to specify Z somewhere
- inside these functions, such as zsin(x), to incorporate F(Z) in the graph.
-
- X Min, X Max -- the range of the X variable
- Y MIn, Y Max -- the range of the Y variable
- X Steps -- the size of the plot in the horzontal direction, 320 or 640
- pixels maximum depending on the screen resolution.
- Y Steps -- the size of the plot in the vertical direction, 200 or 400
- rows maximum.
- MagZ -- an optional magnifier on the value of F(Z) to help speed up color
- changes in a plot where desirable.
- Colors -- the number of possible colors that will be plotted for a given
- range of F(Z). Limited to 16 in hi-res mode and 32 in lo-res mode.
-
- 10 different color palettes are available via the function keys F1 to F10.
- You can cycle through the colors of any palette by pressing the S key.
- These hot keys work any time the plot is being drawn, or when only the main
- window is open.

- A donation of $15 for CPlot gets you the documentation to all my current
- programs, plus additional help with CPlot if you need it, plus any of the
- other programs for $5 off their suggested price, plus upgrade privileges for
- $10.
