[OctDev] error: __getlegenddata__

[Surandokht N. <sur...@gm...>]

Hi there;


I think there is  bug/error while I am plotting:

error: __getlegenddata__: subscript indices must be either positive integers
or logicals
error: called from:
error:   
/Applications/Octave.app/Contents/Resources/share/octave/3.4.0/m/plot/privat
e/__getlegenddata__.m at line 38, column 11
error:   
/Applications/Octave.app/Contents/Resources/share/octave/3.4.0/m/plot/privat
e/__plt__.m at line 57, column 23
error:   
/Applications/Octave.app/Contents/Resources/share/octave/3.4.0/m/plot/plot.m
at line 194, column 9

Here is the script:
a=[];

[files]=dir('*.txt');

for i=1:length(files)

a=vertcat(a,dlmread(files(i).name,'',1,0));

 

 end; 



d=0.01;

doc_ef=a(:,2);

run_doc=0:d:20;

dens_est_doc_ef=kernel_dens(ones(size(run_doc)),doc_ef+5,run_doc);

plot(run_doc,dens_est_doc_ef,'color',[0.9100    0.4100
0.1700],'linewidth',2);

xlabel('a',"fontsize",16);

ylabel('b',"fontsize",16);

a=legend('{\fontsize{16} screen}','{\fontsize{16} screen}');

 text(10,0.5,'No_o_b_s screen=101',"fontsize",12)

grid on


I have to use this again to dauble plotting  in one graph.
The fist time use of this script is fine. No error.
However, when I use for the second time for the second data set, I do have
the above error!

Is there any way to solve this problem?

Your help and advice greatly appreciated.
