[Gnuplot-py-users] Unexpected problem when a many gnuplot windows are open simultaneously

[<kk...@ma...>]

When I try to open more than 6 gnuplot windows at the same time I get 
following issues:
- new windows aren't opened
- gnuplot 'save' doesn't work

I suppose that problem is in gnuplot perfomance. I mean that gnuplot get new 
request before old request is not yet proccessed. Or maybe it is SMP issue 
cause I have Intel Core Duo. Anyway, I've found some workaround:
I've modified __call__ method with short delay. I know it's ugly but it works

    def __call__(self, s):
        """Send a command string to gnuplot.

        Send the string s as a command to gnuplot, followed by a
        newline.  All communication with the gnuplot process (except
        for inline data) is through this method.

        """

        self.gnuplot(s)
        if self.debug:
            # also echo to stderr for user to see:
            sys.stderr.write('gnuplot> %s\n' % (s,))
            time.sleep(0.1);
