I've created Dial Gauge Chart with this query.
select furnaceid, sum(minutesHigh)/sum(minutesup)*100 as PctUP
from casting.high_power
where proddate = '02-feb-2017'
and furnaceid= 6
Under the Series I click on NEW. The column mapping value and maximum value show -select- (in red)
clicking on these provides no options and I cannot enter anything in them.
