Android accelerometer movement detection

I need an application that draws the phone movement graph using Android accelerometer. It shouldn't use any functionalities provided by Android GPS. I know that using accelerometer you can detect the change of (x,y,z) coordinates. I would like to see in a graph, how those coordinates are changing in the real time. As a final result I expect 3 graphs (one for x, one for y and the last for z) that show how each coordinate (x,y,z) is changing in the real time. You are free to use 3rd party libraries if they are open source. For validating the correctness of the graph I will use android nexus one and android samsung galaxy tab devices. Please write me a private message for any question or clarification.
