I posted this over on the octave-help list but it probably should be here.
I am having a problem generating plots reliably from within Octave (Windows
mingw32 version) where Octave will hang some of the time in the process of
generating the plots. After reviewing the threads on the subject, I realized
that this is a recognized issue. The proposed fixes involve:
- making sure Oct2mat.m is not loaded
- renaming
Octave\3.2.4_gcc-4.4.0\share\octave\packages\plot-1.0.7\ginput.m so that it
doesn't conflict with the ginput.m that is part of Octave
- adding sleep(0.05); atline 112 in
...\Octave\3.2.4_gcc-4.4.0\share\octave\3.2.4\m\plot\__gnuplot_ginput__.m
I have just implemented these changes but the problem persists. The problem
is that it is difficult to consistently reproduce. It almost never happens
on my development laptop (relatively slow computer but consistently happens
on the two machine where I have the app deployed (slightly faster
computers).
Here is the function that generates the plots
function status = helio2dummy(test)
NbrImageAnalyzed=1;
dist(1)=27;
NUM=200;
counti=[1:12];
count=[1:12];
dista(1:20)=dist(NbrImageAnalyzed)/10;
figure(1); subplot(2,1,1);
plot(0:11,count');
xlabel('Distance from origin (cm)');
ylabel('Missing dots');
title('Missing dots per cm');
axis ([0 10]);
xl=floor(dist(NbrImageAnalyzed));
xxl=(1:xl)/10;
yyl(1:xl)=20;
subplot(2,1,2);
if NUM<500;
plot(0:11,counti,dista,1:20,"r",xxl,yyl,"r");
else
plot(0:11,counti');
end;
axis ([0 10]);
xlabel('Distance from origin (cm)');
ylabel('Cumulated missing dots');
title('Missing dots per cm (cumulated)');
T1=strcat('test','missdots.jpg');
print((1),T1,'-djpg');
close all;
endfunction
I just put it in a loop with cnt=100 and the problem should appear before
the loop completes.
function status= testloop(cnt)
for i = 1:cnt;
helio2dummy(1);
end
endfunction
Is there anything else I should do to try and work around this issue? Would
increasing the delay in __gnuplot_ginput__.m possibly help?
