What is lmchart and why was it causing type error? What is the effect of removing it? (Obviously it was explicitly included in the sub previously, presumably there was a rason for that?)

lmchart is a function causing the type error as it isn't a table.

I can see in the monitor err log that lmchart is giving an error for not being a table please see below:
"homer.aquaq.co.uk|monitor|monitor1|ERR|sub|Table lmchart not in list of stp pub/sub tables"

From what I can see it looks like this was always causing an error
