plot with reversed y-axis in a normal y-axis (2024)

Thanks.

I have tried that, but it still plot the eye pos using the video y-axis.

I tried yyaxis left and right but it slows down the video when I plot it togrther with the eye pos.

the eye pos are adjusted I belive, because if I plot the video and the eye pos seperately, the position is correct, it is only wrong when they are together because the video y-axis is reversed. I can only reverse it if I flip the image but then the image is not in the right shape.

If the yyaxis command is slowing down the video playback when you plot it together with the eye position, you can try a different approach to adjust the y-axis limits of the video plot to match the reversed y-axis of the eye position plot. Here's an example code snippet that might help:

In this code, we plot the video and eye position separately to adjust the y-axis limits of both plots to match the reversed y-axis of the eye position data. Then we plot them together using imshow for the video and plot for the eye position, with the hold on and hold off commands to combine the plots. We also adjust the y-coordinates of the eye position data by subtracting them from the height of the video and adding 1 to shift them to the correct y-axis position.

I hope this helps! Let me know if you have any further questions.

Thanks.

When I tried that it plots frame 1 then the eye trace on what seems to be a different figure (because the background is white, not the video frame 1 (for ex)), but if i remove the hold off it' ok. However, the eye traces are not in the correct position. Furthermore,it plots the video images in black and white, don't know why.

And I also tried your example, but the eye traces are also plotted in the lower corner of the video, I guess this is not the right position.

Hey Jack,

I was doing something incorrect, but I've corrected it.

Your codes worked ,it flipped the eye pos, but no need for the +1.

thank alot.
