Hi,

I am a newbie and trying to plot a real time X Y plot in java. I am using Net Beans IDE7.2. Data has been sampled at the rate of 250 Samples per second. It looks like as follows 

http://img402.imageshack.us/img402/4927/plotqe.png

Data will be coming into the computer over bluetooth but right now I am trying to read and plot the file. The file can be found at the following link

 https://hotfile.com/dl/185255400/ea220f1/packetr.dat.html

You can better view this file in Hex Editor like HxD from wwww.mh-nexus.de.

I do not know how many samples are in the file. But Data sample is 32 bytes long (from byte 13 to byte 44). This Data is the part of a 46 byte Frame. 

It will be a square wave of 1Hz, if we plot the data. It will be like 2 to 4 sec long wave form. 

I tried to work with the following Code to do this 

1. http://audio-analysis.googlecode.com/svn/trunk/src/com/badlogic/audio/samples/part4/RealTimePlot.java

2. http://www.sharewareconnection.com/livegraph-2-0-beta01.htm


But no sucess. I was not even able to run these above mentioned codes. 

Please advise!
