Thanks for your replies, Jim and Gabor:

Jim:

The x-axis is going to be in log scale. Basically I am comparing two
algorithms. One is very quick and another one is slow. X axis denotes time
and y axis is a normalized solution quality.
I hope it is clear now if not then let me know

Gabor:

I am looking into this Zoo package.

Thanks for your replies
