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.

What is "plate"?

It seems ‘plate’ = ‘plotyy’ + autocorrect.

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:

openfig('FigureFileName.fig');
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.

Yes, created with plotyy, not plate. Darned autocorrect.

[Star Strider]

I suspect autocorrect never heard of plotyy. It’s doing its best.

I don’t understand a .fig file created with plotyy not opening correctly. Were they created with (perhaps significantly) different versions of MATLAB?

Still, I suggest you go ‘handle-diving’ with the get function to acquire the data and re-plot it.

[Roy Goodman]

It was created last September, so 2014a or 2014b. I have both versions on the computer and get the same trouble with each.

[Star Strider]

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.
