ofxgraph's Issues

I wonder how to get buffer sized graph data to my memory, not to csv file in runtime.

Hi, @TetsuakiBaba

I have made a webcam based realtime pixels color value graph.
I've used your ofxGraph addons for OF. Thank you for your great addons.

Then, I wonder how to get buffer sized graph data to my memory, not to csv file in runtime.
My goal is to 1D FFT(a kind of signal processing) of the 1D signal with certain length.

How to get ?

Thanks in advance ~

Best,
