You can do the work yourself (as the axes contains a Position property from which you can determine what you need to crop), but the export_fig function from Yair Altman is probably what you need.
It should be able to export a screenshot of only the axes itself.
Otherwise, you could try digging in the properties to see if there is a CData property you could export directly (which would be the raw underlying data).

export_fig AA.jpg -native -c[31 52 20 25];
the stored image becomes
But, this is not what I want. I only want to store an image like the one given below:
Please, help me. I am stuck.

Perhaps disabling the tick marks before exporting will already do the trick.
