Web service Loadtest: error proportion ?

hi

i m using soapUI to apply loadtest for a web service project.

the question is: how can i know the error proportion?

i mean, from graph, we can only konw the error account is 2732, but how is total error proportion... for instance, if there are altogether 10000 test, and 2732 error, then is error proportion 27.32%, but how can we from soapUI these completely account read/find?

thx
