Hello.
I apologize in advance if this is the wrong list for suggestions for
Mondrian, or if what I suggest has been implemented and I just haven't
been able to find it.
Missing layout: Rectangle packing. There have been quite a few times
when it would be -really- convenient to have the smallest possible
rectangle, but all of the layouts seem to waste space to some degree,
unless the data really -should- be stored in a straight line.
Missing feature: a way to have labels which are always visible, but
perhaps only legible on the larger nodes. [What inspires this is
trying to look at a callgraph using SugiyamaLayout, which works very
nicely, but not being able to label the nodes without it suddenly
being several times wider; the visual information gets entirely lost
in the sprawl.]

Hi Kat,
Thanks for the suggestions.

Do I understand correctly that what you would want is a layout that
given nodes that have different shapes would result in the smallest
possible rectangle? This is something we wanted to do a long time
ago, but we just did not know how the algorithm is called. If you
have some ideas, it would be great to hear them.
The closest possibility we have at the moment is to order the nodes
based on the height and then use a grid or flow layout.

At the moment, the label decides the size of the node. I guess that
what you want is a label that is only partially visible based on a
specified width.
So, in MondrianDevelopment 1.14 I added width to the LabelShape, and
if the width is specified then the label is cropped to that width. It
is still clumsy, because it does not show any sign that the label is
larger. Does this help?
Cheers,
Doru

FYI,
Ricky implemented it for CodeCity, since it's a 2D layout algorithm,
I don't see any major problems with porting it..

Hi,
Could you point me to the layout class?
I tried to take a look at CodeCity to see which is the layout and how
it looks like, but I only got an empty city.
Cheers,
Doru
