Then you have the wrong tool for the job.

The best I could suggest is to consolidate data in 24 hour periods. 
Then using an external script, extract the data for each month 
individually (eg extract the data for midnight 1st July to midnight 
1st August, and so on), and then graph those values with another 
plotting tool.

That will allow you to continue using RRD to collect, normalise, and 
consolidate the data - while using other tools to plot the graph you 
want (RRD won't do that bit).
