Does temperature affect whether or not a current voltage graph curves?

Current-voltage (I-V) characteristics for components

The relationship between current through, and voltage across, a component is called the current-voltage (I-V) characteristic.

Resistor at constant temperature

For a fixed resistor, the voltage is directly proportional to the current. Doubling the amount of energy into the resistor results in a current twice as fast through the resistor. This relationship is called Ohm's Law and is true because the resistance of the resistor is fixed (because the temperature does not change).
