First off, thanks for the great plugin. This plugin is heavily used in our org, and we really like it.

One issue we have seen recently is that sometimes it takes the Jacoco plugin a long time (>2.5 minutes) to analyze data/generate the png graph which is presented in the browser, and (due to our proxy) our browsers would timeout when viewing the Jacoco reports.

After some investigation, we determined it was due to the # of runs in our job (we have ~80 runs). By reducing the 'max # of builds to keep' down to 7, we are no longer seeing this long delay to analyze data/generate the png graph.

Unfortunately, however, reducing our 'max # of builds to keep' down to 7 also means we lose a lot of other data.

It would be very handy if there was a way to use the jacoco plugin and simply turn off the png graph generation. That way we could continue to keep 80 runs (to collect data on intermittent test failures), but could still view the Jacoco reports.
