Problem: figure height apparently limited to screen height

My objective is to save a "tall" figure with a height that exceeds my display height. I used:

>> figure('units', 'normalized', 'outerposition', [0 0 2 2]);

in an attempt to make a figure "taller" (with a greater height) than that of my single monitor. However, the figure resized when displayed to only occupy the screen height (so that the normalized outer position height was effectively "1").

I do use export_fig, and I am unclear if it has an internal solution; the help menu did not specify.

Solutions? Thanks in advance.
