7-12 Draw Operations
All points, lines, and shading drawn on a graph with DRAW operations are
temporary. They remain only until you execute a CLRDRAW (clear drawing)
instruction or a change prompts Smart Graph to replot the graph, at which time
all drawn elements are erased.
To clear drawings from the currently displayed graph, select
CLRDRAW
from the
DRAW DRAW
menu (item 1). The current
graph is plotted and displayed immediately with no drawn
elements.
Note that
CLRDRAW
gives you a quick way to replot the
current graph, in addition to clearing the current drawings.
Begin on a blank line on the Home screen or in the program
editor. Select
CLRDRAW
from the
DRAW DRAW
menu (item
1). The instruction is copied to the cursor location.
When the instruction is executed, it clears all drawings from
the current graph and displays the message
DONE
. The next
time you display the graph, all drawn points, lines, and shaded
areas will be gone.
