png-graph-generator

Bash script for generating a png call graph of a programm.

Uses gprof2dot to convert the callgrind output to a png graph

Usage:

  graph.sh your_program [program_arguements]

Output

A node in the output graph represents a function and has the following layout:

+------------------------------+
|        function name         |
| total time % ( self time % ) |
|         total calls          |
+------------------------------+

where:

• total time % is the percentage of the running time spent in this function and all its children;
• self time % is the percentage of the running time spent in this function alone;
• total calls is the total number of times this function was called (including recursive calls).

An edge represents the calls between two functions and has the following layout:

            total time %
              calls
parent --------------------> children

Where:

• total time % is the percentage of the running time transfered from the children to this parent (if available);
• calls is the number of calls the parent function called the children.
