Paul,
Can you point me in the right direction and confirm the syntax for using the independent option. I am struggling to make the third %pl call in the code below work, where the two graphs with different x axis values are plotted together. Code below fails to draw anything in the third %pl region. I reread the help file many times and tried various combinations with no success.
Thanks
Ken
Code:  program test
implicit none
include<windows.ins>
real(kind=2) x_array_1(10), x_array_2(10), y_array_1(10), y_array_2(10)
integer i
do i = 1, 10
x_array_1(i) = i
x_array_2(i) = i + 5
y_array_1(i) = x_array_1(i)**0.75d0
y_array_2(i) = x_array_2(i)**0.5d0
end do
i = winio@('%ww&')
i = winio@('%pl[native,x_array,n_graphs=1]&',300,300,10,x_array_1,y_array_1)
i = winio@('%pl[native,x_array,n_graphs=1]&',300,300,10,x_array_2,y_array_2)
i = winio@('%pl[native,x_array,n_graphs=2,independent]&',300,300,10,x_array_1,y_array_1,x_array_2,y_array_2)
i = winio@('%ff')
end program test

Ken
For two independent graphs together the number of points must be passed as an array. So in the third %pl, 10 becomes np with
integer np(2)
np = 10

Thanks Paul.
Might be worthwhile changing the text in the help file
from:
In this case the number of data points and the optional xstart and xincrement data must be presented as variables (for one graph) or as arrays (for one or more graphs) where the array index corresponds to the order in which the graphs are coded.

It was the plural "arrays" which confused me.
Thanks
