Save the power spectrum waveform

[johnsold]

Image data is a cluster.  Within that cluster "image" is a 1D array of U8. You can convert that to a string using the Byte Array to String primitive from the Numeric >> Conversion palette.

But then I can't decode it in the python interface. I tried sending it in jpeg string but it also doesn't work. The idea is simples, use the GetImage invoke node, and use the image_data to convert to jpeg string and send that string in a way that python can interpret, like Binary text.

I am going nups, or probably I am not understanding something...

Hi, 

I have two questions, the first is that how to combine many power spectrum measurements in one graph and the second how to save the data it to a file. I am having problems saving the graph due to its being a cluster with three element so it is hard to find any compatible function with it. hope you can provide any hint
