Style CATALOG
Style
equanum,
stylePropertyString
Sets the system graphing function
equanum
in the
current graph mode to use the graphing property
stylePropertyString
.
equanum
must be an integer from 1–99 and the
function must already exist.
stylePropertyString
must be one of: "
Line
", "
Dot
",
"
Square
", "
Thick
", "
Animate
", "
Path
", "
Above
", or
"
Below
".
Note that in parametric graphing, only the
xt
half of
the pair contains the style information.
Valid style names vs. graphing mode:
Function: all styles
Parametric/Polar: line, dot, square, thick,
animate, path
Sequence: line, dot, square, thick
3D: none
Diff Equations: line, dot, square, thick,
animate, path
Note: Capitalization and blank spaces are optional
when entering
stylePropertyString
names.
Style 1,"thick"
¸ Done
Style 10,"path"
¸ Done
Note: In function graphing mode, these
examples set the style of
y1(x)
to
"Thick"
and
y10(x)
to
"Path"
.
