changing milestone

Comment 2 Jiri Sedlacek 2008-04-22 13:35:35 UTC

Caused by inefficient algorithm to draw the chart in Fit to Window mode (several values painted to the same pixel). Will
be fixed by charts reimplementation. Similar issue reported as https://visualvm.dev.java.net/issues/show_bug.cgi?id=8.
