[Plplot-general] What can be doen with this ?

[Piyush L. <pi...@da...>]

Hi=20
Can any body help in the solving my problem ?

When we create a Plplotwin object we specify the viewpoint and window =
boundary using plvsta and plwind option. By doing this we restricts the =
size of the plot to be plotted.
If suppose our data at runtime (say input from some port) increase =
beyond these boundaries. How we can plot this data ? Is there any way ?=20
To make it my problem more clear I am sending the piece of code.=20


package require Plplotter=20
Plplotwin .p=20

.p cmd plsvpa 0.0 100.0 0.0 100.0
.p cmd plwind 0.0 100.0 0.0 100.0


grid .p -columnspan 6 -sticky news
grid rowconfigure . 0 -weight 1
grid columnconfigure . 5 -weight 1

button .bpl -text "Play" -command "play"
grid .bpl -sticky "ew"

matrix x f 2
matrix y f 2=20
matrix x1 f 2
matrix y1 f 2=20

proc play {} {
.p cmd pllab "X-axis" "Y-axis" "MyGraph"
global k=20
global xscroll=20
set xscroll 0
set k 1
while  {$k < 50}  {   =20
.p cmd plcol 1=20
.p cmd plbox "abnhst" 20.0 0 "abnhstv" 20.0 0

x 0 =3D 0
y 0 =3D 30
#I have define the boundary on X-axis 100 here I am exceeding it the # =
beyond the limit =20
for {set i 0} {$i < 300} {incr i} {
.p cmd plcol 5
set a [expr 1 * $i]
x 1 =3D $a
y 1 =3D 30
.p cmd plline 2 x y
x 0 =3D $a

after 25
update             =20
}=20
incr k =20
after 500  =20
.p cmd plspause 1
.p cmd plbop =20
}
}

Please go through this and suggest the needful .

Looking forward for ur reply

Just plotting the data again, specifying the new limits? Or is a strip-ch=
art=20
plotter what you want? see the x17c c example.
