bar graph

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?

Answer 1

[Paulo Silva]

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)
