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".
