No, sorry, we don't offer that kind of the graph. If you're familiar with Excel it'd be fairly simple to get an export of fuel-ups, open it in Excel, and create the graph.
Depending on what you're after with the graph, you might be able to find the info by looking at a chart of historic prices for your area. One reason we haven't done much with prices is that everyone pretty much pays the same price in their own area. So general and personal graphs for a region tend to match very closely.
