cmd_drawfunc |
Function (ROM Call 0x341) |
Executes TI-Basic 'DrawFunc' command.
cmd_drawfunc displays the Graph Screen and draws the expression pointed to by
expr on the screen as a function, using "x" as the independent
variable. For example, to draw the graph of the sine function, you can do:
push_parse_text ("sin(x)");
cmd_drawfunc (top_estack);
Note that the drawn graph is not part of the smart graph feature (see the
TI-Basic manual for more info), and that regraphing will erase all drawn
items.
Uses: ER_catch, ER_success, ER_throwVar, push_expression, push_Float, push_quantum, top_estack, gr_active, OSCheckBreak, is_transfinite, ForceFloat, GraphActivate, GrLineFlt, QSkipGraphErr, XCvtPtoF, YCvtPtoF
