Graphics, Figures & Tables ⇒ tikz node positioning

[CoolnessItself]

I'm trying to make someone to-scale. I know the positions (see code)

Code: Select all

\documentclass[minimal]{article}

\usepackage{tikz}

\begin{document}
\begin{tikzpicture}
\draw[fill=black] (30.3mm,17.5mm) circle (1mm);
\draw[fill=black] (-21.5mm,-23.0mm) circle (1mm);
\draw[fill=black] (-30.1mm,-9.2mm) circle (1mm);
\end{tikzpicture}
\end{document}

It's not necessary that they actually appear at 30.3mm when printed or on the screen, but their spacing should be proportional.

Is this possible?


It looks like this

Your figure shows 1 point at a different location than what you have specified. Changing the following line

\draw[fill=black] (-30.1mm,-9.2mm) circle (1mm);

to

\draw[fill=black] (-30.1mm,9.2mm) circle (1mm);

should give you the proper spacing.

oops! embarrassing! And here I was thinking it was a problem with tikz!

To get closer to what you like to have, you can simply use the pgfplots package.

Code: Select all

\documentclass{minimal}
\usepackage{pgfplots}

\begin{document}
  \begin{tikzpicture}
    \begin{axis}[%
      xmin=-40,xmax=40,ymin=-40,ymax=20,
      xtick={-40,-30,...,40},
      ytick={-40,-30,...,20}
    ]
      \addplot+[only marks] coordinates {(-30.1,9.2) (-7.6,-30.1) (30.3,16.7)};
    \end{axis}
  \end{tikzpicture}
\end{document}
