I am trying to figure out how to setup the following surface chart. Data is fft data
Vector<String>vFrequencies; // y axis lables (frequency)
double dSingleRow; // each value is a frequency level
Vector<double> vAllRows; // each row is another time sample
Date is read in from a stream that is fft'ing a file, in csv it might look like:
Time, 100Hz, 200Hz, 300Hz....
1, -90, -89.4, -89...
2, -89.9, -88, -89.1...
A sample chart is in this github post:
A discussion forum for Orson Charts (a 3D chart library for the Java platform).
