title: Interpreting callgrind data
body: <p>I need a dynamic call graph for my app. I run it with <code>callgrind</code> tool (<code>valgrind</code> suite) and got <code>callgrind.out.xxxxx</code> file. Now, I want to make a graphical representation of this data. <code>KCacheGrind</code> doesn't help me much because it draws a limited part of the graph (draws ~50 functions instead of ~1500 profiled and I don't know how to fix that). How can I get a graph image where all of the functions will be drawn?</p>
