# LaTeX Plot Snippets

The LaTeX package `tikz`

contains a set of commands that can render vector based graphs and plots. This post contains several examples which are intended to be used as a cut-and-paste boilerplate. Each sample comes with a screenshot and a snippet that contains the relevant parts of the LaTeX source code. **The entire source code can be examined by clicking onto the individual images.**

## Scatter Plot

\begin{tikzpicture} \pgfplotsset{ scale only axis, } \begin{axis}[ xlabel=$A$, ylabel=$B$, ] \addplot[only marks, mark=x] coordinates{ % plot 1 data set (0.31,0.28) (0.24,0.50) (0.52,0.1) % more points... }; \label{plot_one} % plot 1 legend entry \addlegendimage{/pgfplots/refstyle=plot_one} \addlegendentry{plot 1} \end{axis} \end{tikzpicture}

## Line Chart

\begin{axis}[ xmin=0, xmax=2000, ymin=0, ymax=1, xtick distance=500, xlabel=Iterations $n$, ylabel=$\mathrm{RMSD}(\hat{\theta})$, ] \addplot[] % no additional information passed to addplot coordinates{ % plot 1 data set (1,0.716) (2,0.6686) % ...

## Two Y-Axes Chart

\begin{axis}[ axis y line*=left, xlabel=$x$, ylabel=$y_1$, ] \addplot[mark=*] coordinates{ (.1,5) (.2,10) % more points }; \label{plot_1_y1} \end{axis} \begin{axis}[ axis y line*=right, axis x line=none, ylabel=$y_2$, ] \addplot[mark=x] coordinates{ (0.18,0.89) (0.27,0.81) % more points }; \label{plot_1_y2} \addlegendimage{/pgfplots/refstyle=plot_1_y1}\addlegendentry{$y_1$} \addlegendimage{/pgfplots/refstyle=plot_1_y2}\addlegendentry{$y2$} \end{axis}

## Function Graph

\begin{axis}[ xlabel=$x$, ylabel=$y$, samples=100, ] \addplot[][domain=-4.5:4]{0.2*x^3-x+1}; \addplot[draw=red][domain=-4.5:4]{3*sin(deg(x))}; \end{axis}

## 3D-Plot

\begin{axis}[ view={20}{10}, legend pos=outer north east, xlabel=$A$, ylabel=$B$, zlabel=$\Gamma$, xmin=5.5, xmax=11, ymin=45.5, ymax=48, zmin=0, zmax=7, ] \addplot3[ samples = 60, samples y=0, only marks, mark=*, ] coordinates { (7.23756,45.9033456,5) (8.712544,47.262364,4) % more data }; \label{c1}

## Histogram

\begin{axis}[ area style, ] \addplot+[ybar interval,mark=no] plot coordinates { (0,.3) % more data }; \end{axis}
