graphics puzzlement

[ji3m]

Maybe im dense but i don't quite get the graphical paradigm of the prime.

Is it just a toy for animating a textbook or what.

What is the point of functions like plotfunc() in cas? It puts miniplots in the history. But for what purpose.? Or line () or point (). Cute pictures in the history seem pointless.

Is it even possible to use graphic functions in a program without invoking all those different spps.?

Graphics on the prime seems very convoluted and fractured and very manually oriented.

Am i missing some simple unifying idea about graphics. Previous hp graphics cslculators seem very simple by comparison.
