usb4000 read spectra convert to waveform

Hi,

I am working with a usb4000 ocean optics device and I wanted to acquire a set of 10 spectra and determine the average before outputting it to a graph display. So far I have been using the 'read spectra' for the usb4000, averaging all the scans in a loop and simply attempting to output it to a waveform chart. But if I do this my resulting spectrum on the graph does not look accurate.

I've attached my file here.

Any help would be much appreciated and please let me know if I need to clarify anything!
