IguanaTex和TikZ

Question

我正在尝试使用IguanaTeX将一些with图片导入到PowerPoint中。

这是我正在试验的代码：

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.7}

\begin{document}

\begin{tikzpicture}[scale=0.50,local bounding box=picture, baseline=(picture.south),
    declare function={binom(\k,\n,\p)=\n!/(\k!*(\n-\k)!)*\p^\k*(1-\p)^(\n-\k);}
]

\begin{axis}[
    samples at={0,...,40},
    yticklabel style={
        /pgf/number format/fixed,
        /pgf/number format/fixed zerofill,
        /pgf/number format/precision=1
    },
    ybar=0pt, bar width=1
]
\addplot [fill=cyan, fill opacity=0.5] {binom(x,40,0.2)}; \addlegendentry{$p=0.2$}
\addplot [fill=orange, fill opacity=0.5] {binom(x,40,0.5)}; \addlegendentry{$p=0.5$}
\end{axis}
\end{tikzpicture}

\end{document}

注意:为了使其正确显示，您需要在IguanaTeX中将默认的DVI更改为DVI。

首先，图形出现了，但在底部出现了一些不必要的空格。因此，生成的图形对于幻灯片来说太大了。我怎样才能删除这个？

其次，如何将轴等更改为白色，而不是默认的黑色，这样我就可以在带有黑色背景的PowerPoint幻灯片上看到图形？

Answer 1

通过设置ymin=0，

• 可以避免图形和轴之间的空间

• 要将轴、标签、图例等更改为白色，可以进行以下调整：

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.7}

  \pgfplotsset{
    axis line style={white},
    every axis label/.append style ={white},
    every tick label/.append style={white}, 
    every axis legend/.append style={white,fill=black},
    every axis/.append style={tick style={white}}
  }
  
\pagecolor{black}

\begin{document}

\begin{tikzpicture}[scale=0.50,local bounding box=picture, baseline=(picture.south),
    declare function={binom(\k,\n,\p)=\n!/(\k!*(\n-\k)!)*\p^\k*(1-\p)^(\n-\k);}
]

\begin{axis}[
    samples at={0,...,40},
    yticklabel style={
        /pgf/number format/fixed,
        /pgf/number format/fixed zerofill,
        /pgf/number format/precision=1
    },
    ybar=0pt, bar width=1,
    ymin=0,
]
\addplot [fill=cyan, fill opacity=0.5,draw=white] {binom(x,40,0.2)}; \addlegendentry{$p=0.2$}
\addplot [fill=orange, fill opacity=0.5,draw=white] {binom(x,40,0.5)}; \addlegendentry{$p=0.5$}
\end{axis}
\end{tikzpicture}

\end{document}
