processing temperature in a real-time graph

Using Arduino Project Guidance
1

Hey,
i started with arduino a couple of days ago and have made my first temperature monitor/sensor.
(measure temperature 5 places with five digital probes)

I would like to show the results from the temperature readings in a real-time graph.
How is this done? Anyone know about a tutorial or something that can teach me?

Take a peak at your Arduino. Do you see any place to display a real-time graph?

Nope. But isnt there other ways to display values realtime? For example Processing 2.1? i have looked at processing 2.1, but cant really figure it out.

There certainly are - a great swag of them.

Processing is just one of many and there have been discussions on this forum featuring some great displays.

You can display them on a graphic LCD on your Arduino, or to a computer in Benjamin Constant over the internet using xively.

About the simplest and cheapest way is by using PL:X-DAQ, which is a free macro for Excel.

Some background is here

Data direct into Excel via PLX-DAQ is fine but I find the live graphs a bit flakey and it might be only practical with one or two lines. I have seen a perfect four-line graph - once.

Thanks Nick, ill take a look at the links.
