CanvasXpress help - fish plot clonal evolution - Javascript

Can anyone help with this code I am trying to amend to create the fish plot with my own data? I am using the fish examples template (I am not allowed to post the link), then click the spanner icon, then clicking on the JS fiddle to edit, and running and know how to amend most of the data and it’s generating what I want. However, when I try to add additional lines of data (literally add more lines under “Data:” for further clones, it keeps hitting an error. Please can someone tell me why and what other fields I might have to also amend. I’ve adusted the vars for the clone names, but it doesn’t seem to make any difference. Please can someone with javascript experience help me as I’m desperate for this diagram for a Uni assignment! Thanks!

please share your code, it’s impossible to help without
