peakdetect | Peak Detection with Golang

I'm trying to use same function on all columns (except 0) on pandas DataFrame. In my DataFrame i have a lot of columns, and if try to write the same code it will take years for me.

I write some code, and you can find it below.

I'm trying to write a program using Javascript and the p5.js library to trigger a random image from an array whenever a peak in an audio file is detected. p5's sound library can detect the audio peak for me and then trigger a function upon that audio peak. However, I don't have much experience in Javascript so I'm not sure where to go from here. I've created an array of images and am planning on creating a function using math.Random to grab one of these images. Can I then call that function within my triggerBeat function?

Also, I've set the image as the background so that it's not within p5's draw function, so I'm trying to change the bg variable. I've preloaded the background image, and I've also got code within the preload function to allow the user to upload an audio file.

Sorry if this doesn't make a ton of sense. I'm pretty new to Javascript and I've spent most of today trying to wrap my head around it.

EDIT: updated code

I'm using google-vision for a project and in particular now I'm using this java class inside my code.I'm doing some stuff with frame detected and now I'm running into this problem: If I use :

I have a spectral data (1000 variables on xaxis, and peak intensities as y) and a list of peaks of interest at various specific x locations (a matrix called Peak) which I obtained from a function I made. Here, I would like to draw a line from the maximum value of each peaks to the xaxis - or, eventually, place a vertical arrow above each peaks but I read it is quite troublesome, so just a vertical line is welcome. However, using the following code, I get "Error using line Value must be a vector of numeric type". Any thoughts?
