I use external .tikz files to include graphics in my LaTeX document. These .tikz files are generated by matlab2tikz. The scatter plots that come out though have very small markers. I want to scale these markers. Right now I include the .tikz file as follows:


How do I scale the markers at the moment I \input the .tikz file. I don't want to edit the content of the .tikz file itself. A method to scale plot markers globally would also be acceptable.

    Try \tikzset{mark size=5} (or some other value) before the \input statement. If that doesn't work, please edit your question to include the code in filename.tikz.

  • I don't know how matlab2tikz handles the plots but you can try adding \tikzset{every mark/.append style={scale=3}} in the preamble.

You can specify the marker size globally by putting

\tikzset{mark size=5}

(or some other value) somewhere before your tikzpicture.

  • what if I actually want to scale the marker sizes, not just set them all to a single size, i.e., I have multiple marker sizes and what the relative sizes between markers to remain the same, I just want to scale everything...
