Program to make graphs of functions of one variable y = f (x) plus full graphics
New version - fixed Seve to disk, and a description of the charts,
implementation of exponentiation eg x^2
Enter the data for the chart function
Axis arguments: Give x1=
Give x2=
Enter the number of coordinates on the x-axis is best (x2-x1) or multiples:
The axis of the function:
fit to mock  
adjust x to [x1, x2] and y to [Y1, Y2]  
align the two scales
Give y1=
Give y2=
Enter the number of coordinates on the y-axis is best (y2-y1) or multiples:
Your rules function - the function arguments must be in brackets, eg: sin (x)
f1(x):
f1(x)=
if($fun1 == 'on') echo "
"; else echo "
"; $k=1; $ikolor='kolor'.$k; echo "
"; for($i=0;$i<27;$i++){ $kol=$color[$i]; if($i==$default_kol[$k]) echo "
$kol
\n"; else echo "
$kol
\n"; } echo "
"; $ikolor='kolor'.$k; $kol=$color[$default_kol[$k]]; echo "
$kol
"; ?>
f2(x):
f2(x)=
