Re: Trying to Plot grid lines every 7 days

[Tim Pierce]

Yes, that must be it

The datetick in octave does something quite unpredictable from the example I gave, where the sin wave wouldbe intact, but it wold stretch toonly the 20th day, instead of the 30th

Thanks

The following gives me the same results in Matlab and Octave.  Is
this, using 'keeplimits' and/or 'keepticks' what you're looking for?

plot( 1:30, sin((1:30) .* (2 * pi / 30) ) )
grid on
set (gca, 'xtick', 1:7:30)
datetick ('x', 'ddd dd', 'keepticks', 'keeplimits')
