PLOT axis labels [message #53194]

Hi

I try to get a plot with only major xticks, but only every other
should be labelled (i.e. every year should have a tick (it is a dotted
vertical line), but only the lines of the even years should be
labelled). How can I do this?

;date_arr consists of [julian day, y-value]

date_label = LABEL_DATE(DATE_FORMAT = ['%Y'])
PLOT, date_arr[0,*], date_arr[1,*], xtickunit='YEARS',
xtickformat='Label_Date', $
xticks=n_elements(x_values)-1, xticklen=1, xminor=1, xgridstyle=1

Thanks a lot for your help
Cheers
Andy
