Bar graphs

Opened this issue · 4 comments

Looking for a good working codes for Arduno and Processing sides to support plot of FFT results in live bar graph style (normally 128 dots).

Plenty of code available on the net if you search ' Arduino Processing Bar Graph '

Marking as a feature request.

In the meantime, one possible workaround is to create a scatter graph (XY), limit it to display 128 points, and plot each of your frequency components at a different x value. You will need to plot each value one at a time, but you will end up with one point displayed per frequency component. You can even use one graph for magnitude and one graph for phase angle.
