Hello there,
I'd like to produce a bunch of customised graphs with gretl in a loop, where I fix the
axis ranges depending on values that I calculated beforehand. A minimum (not-) working
example is below.
-------
nulldata 240
series aa = normal(0,2)
series bb = 2^normal(0,2)
series cc = 3^normal(0,2)
scalar minx = min(bb)<min(cc)?min(bb):min(cc)
scalar maxx = max(bb)>max(cc)?max(bb):max(cc)
gnuplot aa bb --output="bb.png" { set xrange[$minx:$maxx]; }
gnuplot aa cc --output="cc.png" { set xrange[$minx:$maxx]; }
------
This does not work because one cannot pass $minx
Is there another way to do so?
Many thanks
Frederik

Hi,
string smin = sprintf("%f", minx)
string smax = sprintf("%f", maxx)
gnuplot aa bb --output="bb.png" { set xrange[@smin:@smax]; }
might work. Or you could use a similar construct in a "plot" block.
BTW, you can also use "xmin(min(bb), min(cc))" instead of the ternary
statement with "?". A matter of taste, I guess, but slightly shorter.
hth,
sven

Hi, replace the numerical values by strings:
<hansl>
nulldata 240
series aa = normal(0,2)
series bb = 2^normal(0,2)
series cc = 3^normal(0,2)
scalar minx = min(bb)<min(cc)?min(bb):min(cc)
scalar maxx = max(bb)>max(cc)?max(bb):max(cc)
sprintf strmin "%.4f", minx
sprintf strmax "%.4f", maxx
gnuplot aa bb --output="bb.png" { set xrange[@strmin:@strmax]; }
gnuplot aa cc --output="cc.png" { set xrange[@strmin:@strmax]; }
</hansl>
Also, the $-sign is an accessor for internal gretl functions or the loop
only.
Best,
Artur

Wow, that was a quick! Many thanks to both of you, it works fantastic and I learned
something that will be useful in other context, too.

String substitution (using @-variables) will work, as others have
said, but I'd encourage you to consider the more "disciplined"
approach of the (relatively new) "plot" command, as in:
<hansl>
list L = aa bb
plot L
printf "set xrange[%g:%g]", minx, maxx
end plot --output="bb.png"
list L = aa cc
plot L
printf "set xrange[%g:%g]", minx, maxx
end plot --output="cc.png"
</hansl>

Hello Allin,
Indeed this is even better to handle. Thanks a lot!
