自動將甘特圖擴展到頁面的文字寬度

我希望幾乎每個甘特圖都適合自動地到頁面的文字寬度。這個問題中最重要的字是自動的。這就是它與其他類似問題的不同之處。

這文字寬度和時隙數圖表中沒有具體說明。該解決方案應該足夠靈活來處理它。

也許有一個解決方案計算 x unit？下面的MWE有122個時隙。所以我會設定x unit為\textwidth divided by 122.有沒有辦法做到這一點？

\documentclass{article}
\usepackage[showframe]{geometry} % show page borders
\usepackage{pgfgantt}

\begin{document}
\noindent
\begin{ganttchart}
    [
        x unit=1.23mm,              % timeslot width
        time slot format=isodate    % Datumsformat
    ]
    {2017-04-01}{2017-07-31}        % from-to (122 days)

    \gantttitle{Gantt-Chart with 122 timeslots}{122}\\
    \ganttbar{Short}{2017-05-01}{2017-06-01}\\
    \ganttbar{Long Long}{2017-05-25}{2017-06-04}\\
\end{ganttchart}
\end{document}

經過聊天中的討論，這是艾倫答案的改編，它實現了他試圖實現的語法。

答案2

使用calc包裝根據需要設定長度。由於需要在命令中手動設定時隙數\ganttitle，因此我創建了一個ganttchart樣式timeslots，該樣式將圖表的時隙數和最長\gantttitle標籤的文字（逗號分隔）作為參數，然後使用它來計算寬度。它還設定\timeslots可以在命令中使用的巨集的值\gantttitle。

我已將程式碼新增為ganttchart樣式，以便可以像以前的版本一樣在沒有自己的巨集的情況下指定它（有關詳細信息，請參閱編輯歷史記錄）。我還添加了您希望自動調整大小相對於的寬度的長度。對於您的具體範例，它設定為\textwidth，但這允許您將其設定為您喜歡的任何寬度。

用法：[ ..., timeslots={<number>,<text of longest label>}, ... ]

\usepackage[]{geometry} % show page borders
\parindent=0pt
\usepackage{pgfgantt}
\usepackage{calc}
\newlength{\myunitx}
\newlength{\autosizewidth}
\setlength{\autosizewidth}{\textwidth} % this allows you to change the value for autosizing
\newcommand*{\timeslots}{}
\ganttset{
timeslots/.code args={#1,#2}{\setlength{\myunitx}{(\autosizewidth-\widthof{#2}-1em)/#1}
                 \renewcommand{\timeslots}{#1}\pgfkeys{pgfgantt/x unit=\myunitx}}
}
\begin{document}

\begin{ganttchart}
    [
        timeslots={122,Long Long},  % timeslots
        time slot format=isodate    % Datumsformat
    ]
    {2017-04-01}{2017-07-31}        % from-to (122 days)

    \gantttitle{Gantt-Chart with 122 timeslots}{\timeslots}\\
    \ganttbar{Short}{2017-05-01}{2017-06-01}\\
    \ganttbar{Long Long}{2017-05-25}{2017-06-04}\\
    \end{ganttchart}

\begin{ganttchart}
    [
        timeslots={15,Foo},         % timeslots
        time slot format=isodate    % Datumsformat
    ]
    {2017-04-01}{2017-04-15}        % from-to (122 days)
    \gantttitle{Gantt-Chart with 15 timeslots}{15}\\
    \ganttbar{Foo}{2017-05-25}{2017-06-04}
