Ich versuche mit der Bibliothek {datavisualization} die Entwicklung der Daten in Abhängigkeit vom aktuellen Datum nachzuvollziehen.
Ich weiß nicht, wie ich das Datum auf die Abszisse bekomme.
Im folgenden Beispiel ist das Datum im französischen Format TT/MM/JJJJ
% !TeX program =Xelatex+shell-escape
% !TeX encoding = utf8
% !TeX spellcheck = fr

Hier sind zwei Versionen, eine als read from file, die andere aus dem dataAbschnitt, mit demselben Ergebnis.
