Tulip plugins documentation¶
In this section, you can find some documentation regarding the C++ algorithm plugins bundled in the Tulip software but also with the Tulip Python modules installable through the pip tool. In particular, an exhaustive description of the input and output parameters for each plugin is given. To learn how to call all these algorithms in Python, you can refer to the Applying an algorithm on a graph section. The plugins documentation is ordered according to their type.
Warning
If you use the Tulip Python bindings trough the classical Python interpreter, some plugins
(Color Mapping, Convolution Clustering, File System Directory, GEXF, SVG Export, Website)
require the tulipgui
module to be imported before they can be called as they use Qt under the hood.

Colorizes the nodes or edges of a graph according to the values of a given property.
Parameters¶
name | type | default | direction | description |
---|---|---|---|---|
type | tlp.StringCollection |
linear Values for that parameter: linear uniform enumerated logarithmic |
input | If linear or logarithmic, the input property must be a numeric property. For the linear case, the minimum value is mapped to one end of the color scale, the maximum value is mapped to the other end, and a linear interpolation is used between both to compute the associated color. For the logarithmic case, graph elements values are first mapped in the [1, +inf[ range. Then the log of each mapped value is computed and used to compute the associated color of the graph element trough a linear interpolation between 0 and the log of the mapped maximum value of graph elements. If uniform, this is the same except for the interpolation: the values are sorted, numbered, and a linear interpolation is used on those numbers(in other words, only the order is taken into account, not the actual values). Finally, if enumerated, the input property can be of any type . Each possible value is mapped to a distinct color without any specific order. |

maximum value | floating point number | input | That value will be used to override the maximum one of the input property. |

Adjacency Matrix¶
Description¶
Imports a graph from a file coding an adjacency matrix.
File format:
The input format of this plugin is an ascii file where each line represents a row of the matrix.In each row, cells must be separated by a space.
Let M(i,j) be a cell of the matrix :
- if i==j we define the value of a node.
- if i!=j we define a directed edge between node[i] and node[j]
If M(i,j) is real value (0, .0, -1, -1.0), it is stored in the viewMetric property of the graph.
If M(i,j) is a string, it is stored in the viewLabel property of the graph.
Use & to set the viewMetric and viewLabel properties of a node or edge in the same time.
If M(i,j) == @ an edge will be created without value
If M(i,j) == # no edge will be created between node[i] and node[j]
