Hi! i have this pd procedure that uses two arrays.
The first array, the fre_array, is a array that stores 35 frequency values (from 200Hz to 10KHz) and the second array, the amp_array, stores 35 amplitude values. My goal is to plot a frequency vs amplitude graph.

To do that i use tabwrite in a new plot_array.

The right inlet is fed from the fre_array while the left inlet is fed with the correnponding amplitude values.
Since the indexes of the plot_array are actually frequency values that span between 200 to 10000, it make sense to resize the plot_array to have a size of 10000.
Although I think the graph is theoretically ok, i am unable to see it. This is because plot_array has only 35 non zero values in a total of a 10000 indexes array.
Can you share your thought on this? am i doing something completely wrong?

"This is because plot_array has only 35 non zero values in a total of a 10000 indexes array."
But how else can it be, since you're providing 35 frequency values? This means that the rest of the frequencies in the spectrum have zero amplitude...
It sounds like a way to go to me. I tried it and I do get some plot like graph...
