I am working on a SCADA project and I like to display sensor data from the Arduino and the real time clock since it is real time data aquisition. How would I do this?

Have a timer start a routine that reads the current uitable Data property, updates an entry with the current time, sets the new values as the Data property, and uses drawnow() to update the display.
Caution: timers can interrupt running graphics routines. If you have a different graphics routine that is reading and updating the uitable then you could end up a display update missed.
... but why not just update the display when you fetch the sensor values and update the static texts?

In my project, I will take 5 variables from the arduino using fscanf that I would like to print in the table. I don't know how to do it. Please give me an example.
