Changes

The Relationship graph report is made with uses the graphviz GraphViz backend, so which should already be installed, if not you will need to install [http://graphviz.org graphviz] (on linux, use your package manager).

[[Category:Tutorials|Make a relationship chart]] == Before you start ==GRAMPS Gramps can produce charts, but to view them, you need other programs. We recommend that you install the following:* [http://graphviz.org Graphviz]: '''required''' for the creation of the relationship charts

* [http://www.documentfoundationlibreoffice.org/download/ LibreOffice] or [http://www.openoffice.org/ OpenOffice] or [http://www.calligra-suite.org/ Calligra]: for viewing odt documents

In GRAMPS Gramps you can define filters to make a selection of individuals, see [[Example_filters| Examples of filters]]. In the relationship chart all custom person filters you made will be available, as well as the standard descendants and ancestors filters. These last start from the active person.

[[ImageFile:RelationshipChartDescendants.png|right|thumb|200px220px|A descendant chart, click for details]]Download Use the [[example.gramps]] that came with your install, or download [httphttps://grampsraw.svngithubusercontent.sourceforge.netcom/viewvcgramps-project/gramps/trunkmaintenance/gramps50/example/gramps/dataexample.gramps?view=markup&pathrev=10822 example.gramps], on this page use the {{man label|Download}} linksave to a file, create a new database in GRAMPS Gramps called example.grdb, and import the example.gramps data into it.

If not the case, set the active person to ''Garnervon Zieliński, Lewis AndersonSr''.

'''{{man menu|Reports -> Graphical reports Graphs -> Relationship graphGraph...}} In the Bottom dialog:* '''Document Options''' set the '''Output Format''' to .png

In the dialog, set the format to .png and chose Chose the following in the tabs available:#'''Paper Options '''-> Size : Custom Size (Set width and height to ''10000 '' cm, or some other large value)#'''Report Options '''-> ''Filter: '' '''Descendants of Garnervon Zieliński, Lewis Andersson Anderson Sr''' #'''GraphViz Layout optons '''-> ''Graph Direction:'' '''Horizontal (<-)'''#'''GraphViz Options'''-> ''Aspect ratio: '' '''Compress to minimal size'''

(I sometimes experience problems setting the sizes in the Paper options dialog. A workaround is Select '''OK''' to use generate the example using graphviz code in example 3 belowchart.)

The result (using gramps 2.2.7) can be seen to the right. You can use print this on a dedicated printer (check dpi If required change the '''GraphViz Options''' DPI of png!file.), or if you use the default DPI of 72 you can use this image on a website to share. In the last caseexample below, you can use the trick tip explained in [[Make flash plugin from a png]], to make the resulting graph easier to navigate.

In the chart image you see , males in are blue, females in are pink and the yellow balloons indicate a family node in which a marriage date is printed (if known). You can select not to see this family node by deselecting in the '''Graphviz OptionsGraph Style''' tab the option ''Show family nodes''.

[[Image:RelationshipChartAncestors_small.png|left|thumb|350px|Fig. An ancestor chart. For the detailed image, [[Media:RelationshipChartAncestors.png| click here (853kb!)]]]]   Download and open the example.gramps file as in Example 1 -A

Repeat the process in Example 1-aA, but choose the filter ''Ancestors of Warner, Carl Thomas'' this time.  You can see the result to the left.

In order to correctly display the family nodes (yellow balloons), all occurrences of the word ''ellipse'' should be changed to ''egg'' (see [http:/linux/74-ubuntu/www.287-ubuntu-graphviz.org/bugs/b1078.html bug report 1078-viewer-gnome-thumbnailer available]).&lt;/center>|}}

In the menu, select '''{{man menu|Reports -> Graphs -> Relationship Graph...'''}}.

Select in file formatIn the Bottom dialog: graphviz * '''Document Options''' set the '''Output Format''' to ''Graphviz file'', which defaults to the gv extension. This fileis then a dot file which can be processed by graphvizGraphviz.

The Graphviz '''.gv''' dot file is a text file with a well explained documented structure, for extra info(See: [http://www.graphviz.org/Documentation.php www.graphviz.org/Documentation])

charset="iso-8859-1utf8";

dpi="7572"; graph [fontsize=1214]; ....

*For paper size: look for the "page" (paper size) and "size" (area of paper to use), and change these to '''some large values'''. This is important as otherwise the figure will be wrongly scaled giving bad and the picture quality will be poor (eg unreadable text).

...

...

*If you encounter bad fonts (missing characters) or wrong fontsizes, see [[Howto:_Make_a_relationship_chart#Example_3:_Generating_the_graph_by_using_the_Graphviz_command_line_tool|Example 3 ]] on how you can set the font yourself.*If you have a bad resolution of png, eg unreadable text, this is probably because you have set a paper size which is to small. See Exampe [[Howto:_Make_a_relationship_chart#Example_1-A:_a_descendant_chart|Example 1-A]]: set the papersize of number of pages to a high number, but select in '''Layout GraphViz Options''', in ''Aspect ratio'': &lt;<tt>automatically use optimal number pages&lt;Fill the given area</tt>, or use &lt;<tt>Compress to minimal size&lt;</tt>
