**drwls**, Thursday, August 19, 2010 at 7:32amStress equals load divided by cross sectional area of test sample.

Strain equals [(Final length)-(Initial Lelngth)]/(Initial Length)

Since you have only one data point, all you can plot is the stress (y axis) and strain (x axis) corresponding to breakage or yielding.

At loads less than the failure load, there should have been a linear relationship between stress and strain, with a slope equal to Young's modulus for the material. However, you say that you have no data points in this regime.
