給出最小值和最大值的長條圖

給出最小值和最大值的長條圖

我想建立一個類似圖中的長條圖。 圖表

對於每個x值,我都有代表每個條形應具有的高度的最小值和最大值。我的問題是:如何建立給定最大值和最小值的條形,因為在手冊中我只找到瞭如何建立給定座標的條形,如下面的程式碼所示。

\begin{tikzpicture}
  \begin{axis}[
    x tick label style={
      /pgf/number format/1000 sep=},
      ylabel=Population,
      enlargelimits=0.05,
      legend style={at={(0.5,-0.15)},
      anchor=north,legend columns=-1},
    ybar interval=0.7,
  ]
  \addplot
    coordinates {(1930,50e6) (1940,33e6)
    (1950,40e6) (1960,50e6) (1970,70e6)};

  \addplot
    coordinates {(1930,38e6) (1940,42e6)
    (1950,43e6) (1960,45e6) (1970,65e6)};

  \addplot
    coordinates {(1930,15e6) (1940,12e6)
    (1950,13e6) (1960,25e6) (1970,35e6)};

  \legend{Far,Near,Here}
  \end{axis}
\end{tikzpicture}

我認為為此你也可以使用 TikZ。這是一個可能的解決方案,允許自訂軸(xy)、條形(長寬比和寬度)以及插入標籤(在xy軸上)。

現在顯示一個範例,並在其後提供一些有關命令的解釋。

完整的範例使用不同的選項顯示同一圖形兩次:

以開頭的命令\set<element>允許自訂<element>.網格可以透過命令繪製\drawgrid,可選參數在\drawaxes顯示軸時自訂其外觀,但只能自訂箭頭的樣式。對於drawaxes兩個參數是強制性的,它們是表徵軸的標籤。

現在有一些指令可以設定軸刻度和標籤:它們對於xyaxis 是不同的;僅設定可以使用的刻度\setxtickaxes,而不僅插入刻度,還插入軸標記\setytickaxes\setlabelyaxes如果需要插入自己的標籤,可以使用setlabelyaxis[<list of labels>]:此模式根據清單中元素的數量顯示軸刻度和標籤。這兩個例子(現在將插入數字)顯示了這種差異。軸沒有\setlabelyaxis等效項x;這背後的原因是恕我直言,x在繪製長條時設定標籤要簡單得多。其命令是,它需要位置、座標和座標\drawbar作為強制參數來繪製條形。作為可選參數,人們可以自訂欄的外觀並插入標籤。因此該指令的語法為:xyminymax

\drawbar[<customization>]{<x>}{<ymin>}{<ymax>}[<label>]

這是兩個範例的圖(標題問題已修復)。在第一個y軸中,標籤是透過手動插入的,\setlabelyaxes[label one, label two,label three,label four,label five]並且 x不顯示刻度線(我個人更喜歡這種方式)。

[scale=0.8,transform shape]另請注意為環境提供的選項tikzpicture,以避免圖片太大。

在第二個範例中,y軸標籤是自動給出的,x刻度線顯示為網格。

您可以使用 PGFPlots 來執行此操作。與純 TikZ 解決方案相比,這具有處理大值數據縮放的優點,可以輕鬆提供各種不同格式的數據,並允許 PGFPlots 的許多方便功能,例如自動圖例、刻度線、顏色循環列表等

您只需要將列的負數和正數部分分開,然後加到forget plot負數部分:
