How to extract data from reverse quiver plot?

Hi,

I have an original quiver plot. My interest is to extract the data (x-reverse, y-reverse, u-reverse, v-reverse) from the figure with reverse x-direction, as shown in Figure B.

quiver (x, y, u, v) %original quiver plot
set (gca,'XDir','reverse') %reverse in x-direction

By simply change the original x to –x and original u to –u will cause to the undesired change of x-coordinates (-30 to 30 in Figure B).

Can you please help me on how to achieve my objective?

Thanks so much for you help.

Instead of flipping the x axis direction, flip the sign of the x-component of the quiver vectors.

quiver (x, y, -u, v)
