Opening saved figures created using plotyy

I created some figures using plate and saved them as .fig files. Now, I'd like to modify the figures slightly, but they don't render properly when I re-open them in MATLAB. How do I fix this, or at least, get access to the numerical data in the two curves to re-plotyy it.

I never heard of ‘plate’, but if MATLAB will open the .fig files, see if you can get the data from them using the plotyy handle graphics capabilities.
See specifically the sections using the
[AX,H1,H2] = plotyy(...)
construction, and the associated documentation.
Use the get function to see if you can recover them, after you open the .fig file and plot it, for example, something like:
h1c = get(gca, 'Children');
Xdc = get(h1c, 'XData');
Ydc = get(h1c, 'YData');
You might be able to get the data from the .fig file figure handles after you open the figure, and then re-plot them. (If you have access to R2014a or earlier versions, it might be advisable to use them to open the files instead, since the earlier handle graphics are a bit more flexible and easier to work with.)
No promises — I have no idea how ‘plate’ structures its .fig files.

Can you get the data from the .fig file using get? Use R2014a first to get the information from the file. It should work better than R2014b.
Also, unless it contains sensitive information, consider attaching the .fig file here so we can have a go at it. No promises, but likely more productive than debugging the problem over Answers.
