The file seems to save properly, but when I open the ".fig" file in MATLAB, it only appears as graphic. That is, the image is pixelated and the plot's data is not accessible using MATLAB's figure tools. For example, the Data Cursor selects pixel values rather than data points along the curve.

I may be wrong, but I believe that is the normal and intended behavior of the SAVEAS command.
Try HGSAVE instead, that may be what you are looking for.

doc hgsave
doc hgload
