El nuevo comando no funciona correctamente.

Question

Hola, estoy intentando crear un gráfico circular y he utilizado el siguiente código para hacerlo. Importo todo correctamente, sin embargo, no puedo usar el comando de "datos" creado por algún motivo. Recibo el error "Secuencia de control no definida". Qué estoy haciendo mal:

\documentclass[tikz]{article}

\usepackage{pdflscape}
\usepackage[table]{xcolor}
\usepackage[landscape, a4paper, bottom=0cm, margin=0in, top=2cm]{geometry}

Donde "uso" mi gráfico circular en una página 3:

\hspace{2cm}{\Huge \color{customblack1} ABCD inddeling}

\begin{pspicture}(-4.5,-4.5)(4.5,4.5)
    \data[red]{10}
    \data[orange]{40}
    \data[yellow]{30}
    \data[blue]{20}
\end{pspicture}

Hay una macro para gráficos circulares:

\documentclass{article}    
\usepackage{pstricks-add}
\begin{document}

\psset{unit=1.5}
\begin{pspicture}(-3,-3)(3,3)
\psChart[userColor={red!30,green!30,blue!40,gray,cyan!50,
    magenta!60,cyan},chartSep=30pt,shadow=true,shadowsize=5pt
]{34.5,17.2,20.7,15.5,5.2,6.9}{6}{2}
\psset{nodesepA=5pt,nodesepB=-10pt}
\ncline{psChartO1}{psChart1}\nput{0}{psChartO1}{1000 (34.5\%)}
\ncline{psChartO2}{psChart2}\nput{150}{psChartO2}{500 (17.2\%)}
\ncline{psChartO3}{psChart3}\nput{-90}{psChartO3}{600 (20.7\%)}
\ncline{psChartO4}{psChart4}\nput{0}{psChartO4}{450 (15.5\%)}
\ncline{psChartO5}{psChart5}\nput{0}{psChartO5}{150 (5.2\%)}
\ncline{psChartO6}{psChart6}\nput{0}{psChartO6}{200 (6.9\%)}
\bfseries
\rput(psChartI1){Taxes}\rput(psChartI2){Rent}\rput(psChartI3){Bills}
\rput(psChartI4){Car}\rput(psChartI5){Gas}\rput(psChartI6){Food}
\end{pspicture} 
\end{document}
