How to manage two attributes

[Rodolfo]

Hi list! I came from Ucinet, but I want to work with Visone because I
prefer free software. I have read several tutorials, and I learned to
drive mechanically one attribute through the color. But I want to
learn to handle two attributes at once, like i did with Ucinet,
assigning the shape to an attribute, an the color to another. I know
this can be done manually in Visone, but I would like to do it in a
mechanical way... is possible in Visone? Thanks and regards.

Hi Rodolfo,

assuming that you want to assign shapes analogous to colors in a table
mapping (categorical) attribute value to shape, that's not possible in
the current version.
We might implement that in a future version, but then again, for colors
there is kind of an "obvious" choice, so either a mapping of value
range to color range, or just mapping individual values to different
colors (which is basically solved by mapping those values to a color
wheel, i.e.\ the "hue" in HSV).
For shapes, this is a bit more delicate. First of all, there is a
certain limit on the number of shapes to be used in encoding (even with
a key, 32 different node shapes are not helpful at all, and btw. the
same goes for colors encoding categorical attributes).

In short, the best way to go for something like this is to use the
"selection"-tab for the (categorial) attribute you want to map to node
shape:
use it to select all nodes with a certain attribute value and then use
either "node"->"properties" or the context menu of the node and
"properties" there to set all node shapes at once.
You would have to repeat this for every occuring attribute value, but
here, the argument on the number of encodeable categories applies.

anyway, we'll take this into consideration for future releases (a table
mapping wouldn't really hurt), so thanks for the question and I hope
this answer helps for now

Thank you very much Uwe. What you show me is just what I need to do. I have a network with 27 nodes, which are linked to three different attributes. Each attribute has a maximum of four categories, so that although the operation is slightly more complex than in Ucinet, it is not enough to have to resort to other software. Congratulations on the work you have done.  I have followed for many years the evolution of Visone, and this year I plan to learn to use it in depth.
