For images, you need to install libpng and graphviz.
Install libpng

wget -c http://sourceforge.net/projects/libpng/files/libpng15/1.5.23beta01/libpng-1.5.23beta01.tar.gz/downloadtar -xzvf ./libpng-1.5.23beta01.tar.gzcd ./libpng-1.5.23beta01./configuremake && make install

Install graphviz

wget -c http://www.graphviz.org/pub/graphviz/stable/SOURCES/graphviz-2.24.0.tar.gztar -xzvf ./graphviz-2.24.0.tar.gzcd ./graphviz-2.24.0./configuremake && make install

After installation, restart apache.
Service apache2 restart

On the table page, click [View Full Callgraph].
The call performance of each code segment can be displayed as an image.
