Month by month plot

Dear all,

I have a dataset that plotted is the one below (dataset time vs y-value. One value each minute, from January 1st to February 28th).

I would like to plot something like January overlapped to February.

I can do it by manipulating the dataset (on the x-axis I have to use integer number from 1 to the lenght of January and from 1 to the length of February).

Is there a smarter way to plot it directly from the visual object panel?

Thanks.
