Re: [AQT-user] AquaTerm background color using PGPLOT

[Nathan N. <nat...@gm...>]

I am interested in PLPLOT as well, in fact I was wondering whether it  
was a fork from PGPLOT or something because they seem so similar.

I emailed the PGPLOT developer and he was really helpful and answered  
my emails in just a few hours!

Joe: I figured out how to change the lines in PGPLOT and the results  
look pretty good. I may look into PLPLOT but I don't like compiling  
stuff myself and Fink doesn't add the AquaTerm driver and there is no  
PLPLOT for DarwinPorts.

Everything works correctly now, thanks for the help Joe, Per.

Here is my final code, this is Fortran code:
! Just checks to see if the device is available
    if(pgopen('/AQT') .le. 0) stop
! Creates a new "page"
    call pgpage
! Sets the color index 0 to white
    call pgscr(0, 1., 1., 1.)
! Sets the color index 1 to black
    call pgscr(1, 0., 0., 0.)
! Sets the line width to 3
    call pgslw(3)
! Erases the screen
    call pgeras
! Creates a standard viewport
    call pgvstd
! Set x and y range
    call pgwnad(0., 1., 0., 1.)
! Create the plot grid/box
    call pgbox('BCNST', 0.0, 0, 'BCNST', 0.0, 0)
! Set the labels
    call pglab('x(n)', 'x(n + 2)', 'The Logistic Map')
! Plot the points
    call pgpt(n, x, y, 1)
! Close the device
    call pgend
