Generate a moving line plot superimposed over video?
显示 更早的评论
Hello,
I am hoping to generate a line plot that sequentially adds points over time. To make this a bit trickier, I then want to keep the axis zoomed in on the newest ~10s of data so that it scrolls along with it.
Once I hash out this code, I hope to superimpose it over a video. For example, imagine a video of activity on the stock market floor with a moving ticker showing the change in market value over time.
My line data set is a vector and I can convert my video to any format. I am working with very large files right now... about three hours of video and data updates ten times a second. I am starting to think Adobe Flash or similar products may make this easier, but it seems like Matlab should be totally capable of this. Any advice would be greatly obliged!

Did you ever find a way to make this work? I am trying to do something very similar.

I don't know either but I gave him code to get him 90% of the way there.

Yes you can do it. Study the attached demo that builds a movie from images. You just have to create an image somehow, like with plot(). Then use getframe() to extract the image from the axes.
