What we found: The graph is not a straight line which shows that the nichrome wire does not obey Ohm's Law, that is, it is nonohmic.

Ohmic Or NoN ohmic
As the relationship is not linear, the graph is NON OHMIC.
Ohms law states that the Voltage (Potential Difference) and Current of a circuit are both DIRECTIONALLY PROPORTIONAL to each other  therefore a graph produced displaying the relationship between the two would be linear. Hope this helps!
