animation from data files

[Shahid Maqbool]

Dear all,

I have data files in the order like:

data_100.dat
data_200.dat
data_300.dat
...
data_10000.dat

here 100, 200, 300, ..., 10000 are the time steps.

I can successfully plot surface plot for data file e.g., 'data_10.dat' with the command i.e.,

splot 'data_100.dat' matrix with pm3d notitle

Now, i want to make animation for my data files to see the
continuous evolution of the system.

I have gone throught the book 'Gnuplot in Action' and section 11.5 shows some animations, but it is not telling about loading different files. Also the online demos like

https://gnuplot.sourceforge.net/demo/animate2.html

are not very helpful in this case.

So my question is, which commands or keywords should i use to load the continuous files and display the animation on the console?

Thanks a lot.

Best regards,
Shahid

Here something like that (for a temperature-profile in the soil):

set grid
set terminal gif animate delay 0.1
stats "reform4anim.csv" nooutput
set output "animated.gif"
set xrange [0:15]
set yrange [-200:10]
do for [i=1:int(STATS_blocks):4] {plot "reform4anim.csv" u 2:1 index
(i-1) with linespoints t "\@time","" u 2:1:3 index (i-1) w labels t
"","Bodensonde_Statistik_h.csv" u 3:1 t "max" lc "red","" u 5:1 t "min"
lc "blue","" u 4:1 t "avg" lc "black"}

Something like this?

fname(n) = sprintf('data_%.f.dat',n)

n=100
while (n<=10000) {
plot fname(n)
n=n+100
}

Hi

I think that there is no need to use %f, and you can put the name of the file and its definition into the loop, and then it works better!


n=100
while (n<=10000) {
fname = sprintf('data_%d.dat',n)
plot fname
n=n+100
}

Hi all,

Following your suggestions i wrote it like that:

set grid
set terminal gif animate delay 0.1
fname(n) = sprintf('data_%d.dat',n)
n=100
while (n<=10000){
splot fname(n) matrix with pm3d notitle
n=n+100
}

or

set grid
set terminal gif animate delay 0.1

n=100
while (n<=10000){
fname = sprintf('data_%d.dat',n)
splot fname matrix with pm3d notitle
n=n+100
}


but i always get this error:

more> ;splot fname(n) matrix with pm3d notitle ;n=n+100;
^
cannot output binary data to wgnuplot text window

Hi all,
set grid set terminal gif animate delay 0.1 fname(n) =
sprintf('data_%d.dat',n) n=100 while (n<=10000){ splot fname(n)
matrix with pm3d notitle n=n+100 }
or
set grid set terminal gif animate delay 0.1

You must specify a output file name.
set out 'filename.gif'
