How to plot the number of y axis since zero base? Can provide more option?

For example
[ (seq 20 0.1 30) (seq 21 0.1 31) ] |plot

Wish the plot's y axis is from 0 to 31 instead of 20 to 31.

Hmm, that's a good point. What would be better, passing a flag? Or automatic axis scaling?

I think both mode may require, so maybe a flag.
