This file has thefollowing contents, its name is for example timessym.tex. The purpose of the \Ordmacro is to typeset correct ordinal numbers.\usepackage{times}\usepackage{marvosym}\newcommand*{\Ord}[1]{%\ifcase #1\relax%#1\textsuperscript{th}%\or%#1\textsuperscript{st}%\or%#1\textsuperscript{nd}%\or%#1\textsuperscript{rd}%\else%#1\textsuperscript{th}%\fi}A Basic Chart As usual, in the METAPOST input file first the piechartMP module isloaded. The font for text in text mode 0 is set by assigning the name of the Times-BoldItalic metric-file to the METAPOST variable defaultfont. Next the precision of thepercent values is set to 1 and the decimal delimiter to ,, which is more useful for germanpeople. The fourth statement appends the % symbol on the percent value, since the unitshould be displayed too. As you will see the percent values will be typeset in text mode 0,thus a real % symbol is used and not the T E X command \%.input piechartmp;defaultfont := "ptmbi8r" ;SetupNumbers(1, ",") ;SetupPercent(this, " %") ;20
3 piechartMP SetupNext four segments are declared. The segment names are not specified, thus they defaultto the segment number.Segment(32.5) ;Segment(12.8) ;Segment(22.4) ;Segment(18.2) ;Starting the first figure, the first task is always to draw the pie-chart with PieChart.Since the text mode is still 0, that means string based typesetting, the percent values(Label(..)(percent)(...)) will be typeset in the font declared by defaultfont.beginfig(1);PieChart(4cm, 0.1, 65, 0, 0);Label(0)(percent)(inwards,0) ;Now the L A T E X text mode becomes active. You see, the Setup... commands can beplaced anywhere, and modify the behaviour starting from this moment. The commandSetupName declares the string to be attached to the segment name, thus prior to typesettingthe name string for example of the first segment is: the \Ord{1} segment. InSetupName the \Ord command from the L A T E X file is used, thus the name labels have to betypeset in L A T E X mode.SetupText (3, this, "\input{timessym}") ;SetupName ("the \Ord{", "} segment")Label.auto(0)(name)(outwards,0) ;endfig;The command Label(0)(name)(...) draws the name labels for all segments. Theresult is the following figure.the 1 st segmentthe 2 nd segment14,9 %37,8 %the 3 rd segment26,1 %21,2 %the 4 th segmentThe second figure starts as usual. Since the L A T E X text mode is still active all typesettingwill be done in this mode. In the chart the segment values shall be printed. Supposethese values are in unit million Euro, the SetupValue command declares the unit to beattached to the value string. Furthermore L A T E X font commands modify the appearanceof the text, in order to make them bold-italic. Since the Times font is used here too(\usepackage{times} in the L A T E X file), the font of the value labels is the same as ofthe percent labels in the previous graphic.beginfig(2);PieChart(4cm, 0.1, 65, 0, 0);SetupValue ( "\textbf{\itshape ", " million} \EUR") ;Label(0)(value)(inwards,0) ;Label.auto(0)(name)(outwards,0) ;endfig;21
