[Gnuplot-info] PlottingArrays

[Geoff K. <ge...@ka...>]

Dear gnuplot,

I would like to plot a sequence of arrays.

For example, I have a script:

plot-arrays.gp
# TEST PLOT ARRAYS
reset session

array ab1[3] = [ 1.1, 1.2, 1.3 ]
array ab2[3] = [ 2.1, 2.2, 2.3 ]

plot ab1 w lp, ab2 w lp

abname(i)=sprintf("%s%d", "ab", i)

do for [k=1:2]{ abk = abname(k); plot abk w lp }
# END

The first plot command works fine. But I have a large number of such 
arrays and would like to proceed as in the second looped command.

But as things stand, the variable abk is treated as a file name and I 
get the message:
gnuplot> call "plot-arrays.gp"
   "plot-arrays.gp" line 11: warning: Cannot find or open file "ab1"
   "plot-arrays.gp" line 11: No data in plot

I have experimented with macro substitution but not made any progress.

Is it possible to plot an array sequence?

I am using gnuplot 5.2 patchlevel 6, running under Debian Buster
