Interactive Line Plot GUI

Hello community!

I have an interesting problem. I have files of .avi movies typically 40 seconds in length each. I want to make a simple line plot of the movie. The y axis would be empty and the x axis would be the length of the movie in seconds.

Each movie is a set of 10 repetition exercise. I want the user to be able to use the plot interactively to identify the start and stop time of each rep.

So the plot would look something like this:

_-___-___-__-___-___-___-___-___-___-___

With each dash representing a starting and end time of a rep. Is something like this possible in matlab? I also need to be able to store each of those reps.

I know this alot, any advice would be greatly appreciated!

Take a look at ginput2

Thank you, this does look promising. I will download and test it.

Just to clarify, by default the plot should have a line that represents the movie in seconds:

________________________

seconds

then after the user identifies start and stop times of each rep the plot will look like this:

_____-___-___-____-___-____

Quick question: How does ginput2 differ from this:

With GINPUT2 you can also:

1. ZOOM: in, out (double-click)!

2. PAN: when dragging!

3. DELETE: last selected point!

4. PLOT: while selecting! (optional, just input the line style!)

5. SCALE or GEOREFERENCE images! (optional, just input: true)

I see. I dont need 1-4 or 5. Just 4 for my problem. But it looks like it wont be able to do even that. Or maybe I just dont know how to do it yet.
