bar graph
显示 更早的评论
Hello,
I am using a bar graph as a type of timer that shows how long is left on a running program. In the actual code, n will equal a variable
n=runningtime
for the below example, I just used the number 4
n=4;
for i=1:n;
pause(1);
i;
bar(i);
axis([0.9 1.1 0 n]);
hold;
end;
pause(1);
close
When I run this code, I get: Current plot held, Current plot released, Current plot held, Current plot released, etc, etc, depending on how many times it runs, based on the number that n equals. My question is how to stop this from displaying in the command window?

remove the
hold;
and put
hold on
before your code
Here's a better way to do the same thing
h = waitbar(0,'Please wait...');
for i=1:4
waitbar(i/4)
pause(1)
end
close(h)

Rather than use hold, why not do
h = bar(1);
axis(...)
outside the loop, then in the loop do
set(h,'YData',i)
