am trying to use tk:graph for some real time data plots but am unable to put time on the x-axis. see the Link below. http://www.stonehenge.com/merlyn/LinuxMag/col59.html I need to create almost the same program but with Time on the x-axis. I tried using a data hash etc but it did not seem to work. Are there any alternate good simple options for plotting data in Real Time.....?
