Gnuplot: can I make x axis stretch at some data points?

Question

I have vector of time points which will be represented at x axis.
some of these time points occur at certain sign and other time points occur at different sign.
I want to scale x to y for first sign as x=1:y=1 .
I want to scale x to y for second sign as x=2:y=1
So that I will have one graph with x axis stretched at some points" x unit = double space e.g. 2 cm for 1 hour" and contracted at other points "x unit= single space e.g. 1 cm for 1 hour"
I have array with same index as time array which has 1 for single space time points and 2 for double space time points.
can I plot this in gnuplot?
