/****************** 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.
