Median for Graphs

We are analyzing how long it takes our projects to complete. We have a lot of outliers, and median works well to answer the question that we currently have. To do this we export the report and calculate the median in Excel.

Could you add a Median to the drop down in the Graphs? Right now the options are Count, Sum, Minimum, Maximum, Average.

We'd like to add Median, and while you're at it if you could add Standard Deviation, Mode, and Range.
