There will not be a limit to how many function types we could possibly program, and it does not feel like there is going to be a single universal input form or program to run them, so we will use an index form to manage them.
The main form will be a switch board into the equation forms and the axis form, but also will set the layer color and lineweight, text style, and background color. Being able to change these easily will improve the screenshots.
Main Form – contains the button links to other forms, and the settings.
XY-Axis Form – strictly for drawing the axis
Graph1 and Trig1 forms contain the draw sub-routines. they can be expanded and more added.
