Hello Mr.Br=C3=B6ker,
Thanks for your help. I got what you want to explain about pipe. I used the
pipe to send commands to gnuplot from Visual Basic (Shell and Sendkeys
functions in VB). =20
But my gnuplot command is a curve fitting function for which initially I
guess parameter values a and b and then gnuplot will do fitting and display
final set of parameters.=20
Now my question is that is there any way by which gnuplot can store, send
back those a and b variables to VB and then I pipe these final values again
to gnuplot. This can give me complete automation.
Thanks,
Gopesh
