Change x axis in version report for completion date prediction

[Maximilian Reff]

Hi,

the regression line of the completed work in the version report stops before crossing the graph of the total scope of the backlog, due to the x-axis, that ends to early. So the predicted completion dates are wrong, because the report displays not the calculated completion dates but just the end of the regression line. 

Is it possible to enlarge the x-axis manually oder solve the problem in a different way?

Thanks
