Hi there I was wondering is it possible to only use the absoluteTimeScale option and set it from 12:30am - 7:30am?

or do you have to use other options also? Thanks

Not half hours but you could set 1am-8pm or 12am-7am for instance, If you use absolutetime scales the plugin looks at the current Hour to see if there is a value for that hour within the "absoluteTimeScale" config options
