Can we create ONE bar chart or line graph that compares data year over year?

Can we create one bar chart or line graph that compares a single usage data metric, for example, from Jan - June 2015 and Jan - June 2016 overlaid on the same chart?  I'm not looking for two charts side by side but rather for a single chart where I can easily see the trends over specific months compared to each other.  If this is not currently possible, are there plans for adding year-over-year reporting?  Thank you.
