title: Dynamic Graph Plotting with openGL in Android
body: <p>I want to plot real time data from a bluetooth device.  I have a Bluetooth device that the phone will connect to and read the data coming from it.  The data is voltage levels from some sensors and having a sample rate of 300 samples per sec.  Most of the plotting libs(like aiChart, Androidplot, achartengine,...) I have seen can't handle that amount of data and repainting the graph.  So I looked into openGL and Android NDK and it seems that I might be able to graph using either one of these with the sample rates I have. Does anyone have a sample code for openGL line graph plotting in android/Java and/or NDK code sample?   </p>
