使用gnuplot的动画：只有一个在动画中绘制的cruve，而2个则预期

Question

I have the following script which is expected to produce the animations of 2 curves :

#!/bin/bash

for i in {1..397}; do
gnuplot -p <<-EOFMarker
set terminal png;
set output "pic$i.png";
set title "power spectrum";
set xlabel "scale (k)";
set ylabel "P(k)";
set key top left;
set grid;
set ytics out nomirror;
set xtics out nomirror;
set logscale x;
set logscale y;
set format x "10^{%L}";
set yrange [0:30000];
plot "CAMB-1.3.5/matter_camb$i" u 1:2 w l;
replot "EFTCAMB_v3_beta/matter_eftcamb$i" u 1:2 w l;
EOFMarker
done

# Build movie with ffmpeg
ffmpeg -start_number 1 -i pic%d.png  movie.mpeg

Every works fine excepted the fact that only one curve is plotted in animation (CAMB-1.3.5) :

Here is an example of frame :

为什么在生成的图像中未考虑“ REDETOT”命令？

Just for the sake of the SO-rule "no answer in comments":

Check help plot:

 语法： 

      绘制{＆lt; ranges＆gt;}＆lt; plot-element＆gt; {，＆lt; plot-element＆gt;，＆lt; plot-element＆gt;}
 

 示例： 

      绘制罪（x）
      绘制罪（x），cos（x）
      图f（x）= sin（x*a），a = .2，f（x），a = .4，f（x）
      绘制“ datafile.1”，带线，“ datafile.2”带上点
      图[t = 1：10] [-pi：pi*2] tan（t），\
           “ data.1”使用（tan（$ 2））：（$ 3/$ 4）平滑CSPLINES \
