Hello
I created the differential plot attached with Matlab. Is it possible to retrieve the derivative data it used or do I need to calculate it myself?

I looked at the data in this file.
One way to recover the 5003 Line objects is:
filename = '1wavevec.fig';
F = openfig(filename);
Ax = gca;
Lines = findobj(gca, 'Type','Line')
for k=1:numel(Lines)
xv{k,:} = Lines(k).XData;
yv{k,:} = Lines(k).YData;
end
However the rest of it makes essentially no sense. It appears to be entirely made up of collinear quiver arrows and nothing else. I have no idea how to recover any information other than the quiver arrows that comprise each line.
It will likely be necessary to calculate whatever data were used to create this plot and use that, or re-plot the existing data without using the quiver function. I doubt that anything meaningful can be recovered from the file as it exists here.
