思维导图无法与日历配合使用

Question

按照 Tikz 和 Pgf 手册，思维导图教程 - 添加日历后，思维导图消失了！

有人有这些例子的完整 LaTeX 代码吗？真是令人沮丧……

这是我的代码：

\documentclass{article}%
\usepackage{tikz}
\usetikzlibrary{mindmap, trees, calendar, shadows, backgrounds, calendar}

% Define macro for annotations
% #1 - number of the lecture
% #2 - name of the lecture
% #3 - positioning options, like 'above'
% #4 - position where node is placed
% #5 - list of items to be shown
% #6 - date when the lecture will be held
\def\lecture#1#2#3#4#5#6{
    \node[annotation, #3, scale=0.65, text width=4cm, inner sep=2mm] at (#4) {
        Lecture #1: \textcolor{orange}{\textbf{#2}}
        \list{--}{\topsep=2pt\itemsep=0pt\parsep=0pt
        \parskip=0pt\labelwidth=8pt\leftmargin=8pt
        \itemindent=0pt\labelsep=2pt}
        #5
        \endlist
    };
    % Place in calendar
    \node [anchor=base west] at (cal-#6.base east) {\textcolor{orange}{\textbf{#2}}};
}

输出如下：

Answer 1

问题出在这行：

at={(-5.\textwidth-5mm,.5\textheight-1cm)},

当然 - 这只是一个简单的点，放错了位置：-5.而不是-.5：

at={(-.5\textwidth-5mm,.5\textheight-1cm)},

可惜没有错误消息可以阻止这种事情发生。

zip另外，可以在下载文件中找到示例的源代码，doc/generic/pgf/text-en在我的例子中，该文件名为pgfmanual-en-tutorial-map.text。
