cile
x. cile values of y.
example:
3 cile i.12
fitrect01
fit rectangle data to 0 1
form: [anisotropic] fitrect01 data
if left argument is 1, applies same factors to both columns
otherwise, scales columns independently.
fit01
fit data to range 0 1
form: [anisotropic] fit data
if left argument is 1, scales columns independently,
otherwise applies same factors to all data,
gbitmap
bitmap viewer using isigraph control
y. is a boolean matrix
Note max size is about 80 x 80 - after which the graphics buffer
is full.
This function is fast for small bitmaps. Use viewbmp in bmp.ijs
to display larger bitmaps.
e.g. gshow gbitmap ?40 40$2 [gopen''
gfit
fit data to graphics window
scales each column of data independently to range (0,1000)
glines
display line connecting points
{color;width;style} glines points
points should be a 2 column matrix of xy values
gopen
open graphics window
y. = controlname;parentname
if either empty, default to 'isigraph'
e.g gopen ''
gopen '';'J Graphics'
gpen
set pen color [;width,style]
(default 1,0}
gpolygon
draw polygon given points
{color} gpolygon points
grayscale
generate grayscale
example:
grayscale (i.%<:) 5
hue
generate color from color set
x. is color set
y. is values from 0 to 1, selecting color
hueRGB
generate color from RGB color se
x. is RGB color set (default HUES)
y. is values from 0 to 1, selecting color
polygon
vertices of a regular polygon
y. = number of points
x. = scale factor on angle 2p1%y. (default 1)
e.g. polygon 5 = pentagon
2 polygon 5 = 5 pointed star
rotate
rotate angle by given amount
e.g. 0.5p1 rotate points = rotate clockwise a quarter turn
