A colleague of mine who worked on the same project retired one year ago. I would like to use some of the data he measured and reproduce some of his figures. He gathered the data while performing a routine analysis of our raw material e.g binding kinetics or adsorption isotherms. In general, nothing groundbreaking. Unfortunately, he did not publish the particular dataset. As a consequence, I cannot cite him.
How can I use that data without being accused of plagiarism or fraud. Of course, I will ask him for the permission to use that data.
Would you state that in the introduction or the figure legend? And what would you write?
I forgot to mention that I will write my Thesis as a monograph and publish it later.
