Simple, efficient, and user friendly replacement for waitbar.

| Watch this File

File Information

This implementation of progressbar is intended to be extremely simple to use while providing a high quality user experience.

  - Can add progressbar to existing m-files with a single line of code.
  - Supports multiple bars in one figure to show progress of nested loops.
  - Optional labels on bars.
  - Figure closes automatically when task is complete.
  - Only one figure can exist so old figures don't clutter the desktop.
  - Remaining time estimate is accurate even if the figure gets closed.
  - Minimal execution time. Won't slow down code.
  - Randomized color. When a programmer gets bored...

  n = 1000;
  progressbar % Create figure and set starting time
  for i = 1:n
      pause(0.01) % Do something important
      progressbar(i/n) % Update figure

Great work. Cheers !

Great code!This simple and useful!

Only one problem (and fix): there is a warning given at each bar update when the default interpreter is set to 'latex'. I fixed it by explicitly setting the interpreter in the two ext object to 'none' (lines 221 and 226).

John: Thanks for the comments. (1) Only allowing one progressbar was an intentional design choice. (It's described as a feature up above!) When I'm writing new code or debugging I often crash or dbstop and this prevents the old progressbar(s) from hanging around forever. (2) That is certainly possible and might be useful. I encourage you to try it yourself and post back here!

Hi Steve,

I can see two improvements. One, is to return / take a handle to the figure, so that multiple progress bars can be implemented, in order to track different completion times or subprocesses. And, second, the scripts I'm running a long time. So estimating the completion time on the outer loop isn't too helpful. Could you include the estimated completion for each loop, possibly as text over the bar for each loop.

Alfredo: I really don't know how parfor loops work. You'd need some way to know when each "iteration" completes so you can update the progressbar. If you figure it out, please post back here!

Hi Steve, would it be possible to integrate it in a parfor loop? I've tried to call it inside a parfor loop with argument provided by function parfor_progress ( but it doesn't display progress. Thank you!

14 Oct 2015 James O'Brien

For the very time-intensive code I have, this is a great way to know that it is running - along with the progress. The "waitbar" function added a huge latency, so I just had an ugly text display "% Complete" in the window. Matlab sorely needs to update these type of functions.

This is great for showing off to the upper management, and looks much more professional.

Thanks Steve. Nice work!

Anthony: You're not the first person to ask... see the older comments. It is certainly possible to integrate progressbar into an app, but I've never done it and it won't work as-is. You'd need to make it draw into your GUI instead of its own little window. Good luck!

Hey Steve,

First off the code runs very well but I have one question regarding implementing it with a GUI. I was wondering if there is any way to add the progressbar window to a currently existing GUI window instead of the progressbar being its own separate window? Is this possible?

Best Regards

11 May 2015 Jonathan

Nice work :)
I've added a customized close function which stop the main program. It is not very elegant as it's base on removing the path to "progressbar.m" but it works (without bringing change in the main).

Hello, first of all, thank you very much for your submission.
Second, when I update the second progressbar, labels are deleted.
I have MATLAB 2014b.
Any idea?

02 Dec 2014 Steve Hoelzer

Steve Hoelzer (view profile)

raunak: If your inner loop calls progressbar(1) then the bar is closed and the labels are lost. You can initialize the labels in the outer loop so they are recreated for each inner loop.

Steve, I have a question.
When I use a loop inside a for loop which does not contain progressbar ftn call, then the progress bar naming disappears in the main progressbar loop call. How to tackle i?

Awadhesh: The comments at the top of the file show two ways of handling nested loops. You can adapt those to your situation. Here's one way to do it:

progressbar(0,0,0) % Init 3 bars
for i = 1:m
progressbar([],0,0) % Reset 2nd and 3rd bar
for j = 1:n
% do stuff
progressbar([],j/n) % Update 2nd bar
for k = 1:p
% do stuff
progressbar([],[],k/p) % Update 3rd bar
progressbar(i/m) % Update 1st bar

Hello Steve,
I have a for loop and inside that i have 2 separate for loops. For example:
for i=1:N
for j=1:p
% my code here

for k=1:m
% my code here

How to use your progress bar to show the progress of all the three loops with the outermost loop being the main one?

I figure out how to place the text inside of the progress bar for a single progress bar. Comment out if length(progdata) > 1 and the end for the if. Also you can change 0.99 to width/2 to move the progtext location to the center of the bar.

With regards to cancel functionality:
Couldn't you use something like waitbar does where you use appdata() to tell it if you're cancelling?

My previous comment got deleted somehow. Here it is again:
"Doesn't work for me, at least with multiple bars updated independently. The upper-level bars are never updated, only the innermost loop. The help example "% Simple multi bar" shows this. It DOES work if the bars are updated simultaneously.
Shame, because its a great piece of code.
I've got (R2008b)"

I forgot, with multiple bars updated independently, it deletes the names assigned to the bars at initialization...

Boris: Thanks for the comments!

1. That would be nice, but I don't think it's possible inside progressbar itself. It might work to put a try-catch around your code and have the catch call progressbar(1) to close the bar.

2. I've tried, but can't get it work quite right. See my previous comments.

3. Also a good idea. I believe others have modified my function to work like you describe, but I've never gotten around to doing it myself.

Three things:
- The progress bar should be removed when the program finishes - even when interrupted (might be a hard one)
- A cancel button to interrupt the program might be handy right there
- the bar should integrate into the interface a bit better (docking - or in status bar of editor)
Otherwise - nice work!

Hey Benjamin. Your addition of embedding the progress bar into the GUI seems very interesting. How did you do that? Can you post or mail your file? Id love to see how its done(I didnt manage to do that).

Also Steve, thanks for making this nice tool:)

This is a great piece of code that I use all the time. I appreciate how well commented the code is.

I made some updates so that the bar(s) can be embedded into a gui. I would be happy to send it your way if you like.

Gianluca: Thanks for the comments!

I'm not familiar with MATLAB's parallel computing features, so I don't know for sure what's going on. My guess is that you can't update local figures from "workers", so you need to monitor their status somehow and update progressbar locally. Let me know if you figure out how to make it work.

10 Jun 2011 Gianluca

Thanks Steve for this fantastic tool, very simple, handy and efficient.

Is there any way to make it work in parallel computing. I run a simple test just using you "simple bar" example and it does not update the bar under the "spmd" function. Any clue of the reason?

Wow, really great work! Love it and it works like a charm.

For my purposes though, I took the liberty of editing around in your code a bit. What I did:
- Changed from function to class, so multiple instances can be run easily and without interfering with each other.
- Incorporated label changes during execution. The bar_text property can be edited and applies again when the figure updates.
- Made the calculation of the remaining time more accurate by taking the mean of all iterations already done as iteration time.

I could send you my modified file if you'd like to have a look!

Halil: There is no way to update labels without resetting the whole progress bar. I'd welcome code to implement that feature... :)

You're right about the remaining time calculation. I did it that way because of my concept of what multiple bars represent. I always think of the top bar as progress of the overall task, and other bars as progress of sub tasks. For an example of how I would use it, look at the "Fancy multi bar" demo in the progressbar's comments.

14 May 2011 halil sen

sorry about the mess, firefox failure. i wish there were a delete comment button...

anyways, first of all thank you for this efficient, fast, and handy function. i wonder whether it is possible to update the 'Label' of the bars or not. OR is it doable?


EDIT: also, one last thing as far as I can see, the 'remaining time' calculations only depend on the first bar's runtime but this is sort of misleading. maybe, the way how the remaining time is calculated can be optional (e.g. max/min of the remaining time of all bars or the bar(s) that will be used in calculations may be specified by the user or both options at the same time etc.) nevertheless, stating this calculation fact in the Help would be nice and explanatory.

btw, pardon me if i'm wrong about the way of time calculations.

Quite superior to waitbar. One feature I'd really like to see is the ability to update the progress bar label(s) without resetting the progress bar and timer, letting you inform the user exactly what process or subprocess is taking so long. Excellent job on this very handy function.

Jveer: I've played with adding pause and abort buttons but I was never totally happy with how it turned out. The main problem is that those buttons are unresponsive in the time period between calls to progressbar. You click, and then wait until the next call to progressbar before anything happens. In some of my own code, that could be 10 minutes or a half hour. And sometimes the click isn't captured so you never get the desired behavior at all. So far I've chosen to do without rather than add a half-broken feature.
