[mostafijur]

Hello

I want to show continuous graph using Gnu plot. That means after 1 hour I want to see previous every 10 mins[Lets] graph.

Gnu Plot Version: 4.0,
Linux kernel: 2.6, UBUNTU

I can access Gnu plot using C language in Linux.

Is it possible to show scroll bar in Gnu plot graph window to see previous graph?

If possible please can you tell me how? Or, If u have any link please can u give me?

Thanks...
