Hi,
A collegue of mine added in graph_api.php the possibility to show all the subprojects in one graph (so as the main project) in stead of showing only the selected subproject. The version of mantis we are using this in is Mantis 1.0.0rc1.
the code for this is as follows (I will post the whole code here since this is easyer and I cannot add an attatchment):
