Google charts
h am trying to impliment google charts on my page to show a comparison between 2 years split by month,
to try and understand and to simplify the initial graph i used an example graph straight from the google charts docs.
this worked fine till i added my own data now i get no display, but if i veiw source the code is all in the page with the correct data,
i have filled out the dataloader with the correct data programmatically
here is the view source
here is the page code
any help you could give me here would be greatly appreciated

Dual-Y charts
https://developers.google.com/chart/interactive/docs/gallery/columnchart#creating-material-column-charts
This worked as is, when i added my data it stopped showing on the page but in view source it is there with my data added, i am assuming this is because i am adding the data through variables instead of through a JSON array.. but it worked with hard coded data i thought variables would be the same to hard coded data to the graph
