Dear Allin,
thanks again for your examples. These are nice illustrations and I
wasn't aware of some of the capabilities of gnuplot.
In order to handle different time frequencies more flexible, I
thought it could of an advantage to exploit the $obsdate series
which actually contains all necessary information. In the attached
example, I transform the int values of $obsdate into an array of
strings and use these string values (separating year, month, day)
as xtics in a flexible manner. This also allows the user to define
different options on how to present dates, as you will see below.
Yes, that's nice, I agree.
Btw, there is a weird thing for large matrices with my obs. as
used below. In order to generate a proper graph one needs to
write:
<hansl>
printf "set style fill solid border -2\n"
# "border -1" doesn't work for long data!
</hansl>
Not really so weird. The number that (can) follow "border" in this
context is a line-type. Line type -1 is a solid black line. So with
"border -1" and the daily djclose data you're requesting that each
of the 2528 boxes is bordered by a black line. That produces a
totally dense black mass with no pixels left to show any colors.
Line type -2 doesn't exist, so (by courtesy, it seems) if you say
"border -2" that's equivalent to saying "noborder", in which case
the selected colors for the boxes are visible.
