npn simulation producing linear collector curves

I'm attempting to produce the collector curves for the BJT however it is producing idea/linear curves as show below

I want it to give a curved plot like below:

Collector Characteristic Curves


Please provide assistance on how I can fix this.

the NPN model is: is = 1.5E-14         bf = 200                rb = 75                  vaf = 100

below is the circuit

Reduce the increment value of your voltage steps.  I ran your simulation with it set to 500u volts and got the results you're looking for.
