You could export the data grid to Excel and remove the unknown data. Then you could customize the graphs any way you want. This is how I do it as I find the TD graphs are pretty bland and permit very little customization.
Success is the ability to go from one failure to another with no loss of enthusiasm.

yep as rich says, i have yet to find a context, where i have kept the out of the box graphs and reporting from TD and have always had to bring the reporting information and metrics out to excel to achieve the sort of graphs and statistics (trend metrics) I want.
