I have installed portable java8 in /context/java, so paths will not be
needed when using absolute paths with the commands in these files. When I
execute the following batch file sample2.bat with a command on a single
line, it will create the sample2.png wordcould file as expected in the
/context/documents folder:
/context/java/bin/java -jar /context/wordcloud/ibm-word-cloud.jar -c
/context/wordcloud/examples/configuration.txt -w 800 -h 600 <
/context/wordcloud/examples/hamlet.txt > /context/documents/sample2.png
I now use this test2.tex file with filter with the defineexternalfilter
command on one line without crlf or spaces:
\usemodule[filter]
\defineexternalfilter[wordcloud][filtercommand={/context/java/bin/java -jar
/context/wordcloud/ibm-word-cloud.jar -c
/context/wordcloud/examples/configuration.txt -w 800 -h 600 -o
\externalfilteroutputfile\space -i \externalfilterinputfile},
output=\externalfilterbasefile.png, readcommand=\ExternalFigure,
continue=yes, read=yes, cache=yes, purge=no,]
\def\ExternalFigure#1{\externalfigure[#1]}
\traceexternalfilters

Een bak cijfers vertalen naar een visuele weergave kan ervoor zorgen dat
statistische data beter gecommuniceerd wordt. Grafieken zijn zoals Tufte
(1997), een bekende auteur op het gebied van analytisch ontwerp, zegt
instruments for reasoning. Voordat het zover is zullen echter eerst een
paar stappen genomen moeten worden. Ervan uitgaande dat de bak met data al
verzameld is moet er gekeken worden welke cijfers met elkaar in verband
kunnen worden gebracht. Is er een ontwikkeling in tijd, zijn er
verschillen, is er een stijgende of dalende lijn in te ontdekken etcetra.
Door deze data te rangschikken en te ordenen kunnen deze patronen zichtbaar
gemaakt worden. Ontwikkelingen, schommelingen hierin, de frequentie
hiervan, onderlinge relaties en een totaaloverzicht kunnen in beeld
gebracht worden.
