How to ignore some builds in Hudson test results trend?

Sometimes the hudson build step fails and does not execute all my tests, which really screws up the test trend graph because it shows a 50% drop in the number of tests and then goes up again. Is there a way to exclude the failed builds? I tried to delete the whole failed build but that didn't help.开发者_如何学JAVA

If you delete the "offending" build and then run another build I think you'll find the trend graph is rebuilt without the blip.

That said, I have to side with @DarkDust on this one. If your CI environment is prone to wobble then these stats can be useful for diagnostics.
