Created vs Resolved - fixed start date

Hello,

I have a suggestion for an improvement to the Created vs Resolved Chart.
Currently you only can set how many previous days should be displayed on the chart. If the project (displayed on the chart) keeps going on you have to change the number of days over and over again to display full set of issues.

My suggestion is to add an alternative way to set the period displayed on the chart: if only one could set the start date (fixed date) from which the chart should start displaying issues and the end of this period should automatically change to the current date. In this way the chart will be always up to date without any need of user intervention.

I think it would be a major improvement to the functionality of this chart.
