Hi,

To have a line that breaks you will need to have dates in your series for
the weekends and no data for the equivalent points.
If you just made the axis Time series the line would be interpolated between
Friday and Monday data points.

Cheers

my chart displays the efficiency of machines per day in one month.
as we do not work on Saturdays and Sundays I do not have any values for
those days, but I still want to keep the days as we might work Sat. or
Sundays.

How can I have the line of my graph interrupted instead of connected
between Friday's and Monday's values?
