First of all, thank you educating me about this. I read a number of
your articles on the precision of numbers, and I've finally got the
double precision values I was seeking. However, when I try to put
them on an x-axis, they appear to revert back to single precision
values. The array of values are definitely double precision, and I
set xtickformat='(F20.5)', but sadly the labels appear to be (single)
floats disguised in the F20.5 format, and the data being plotted is
clumped into groups instead of nice and continuous (perhaps because it
sees big gaps in the x values due to their single precision?). I am
hoping this is a minor step I've missed in the keywords to PLOT.
