[Tex/LaTex] PGFPlots: Make tick labels tiny

pgfplotstikz-pgf

I want to make the tick labels tiny in size. Additionally, I need to hide the z-axis. Finally, I would like to suppress the y-axis tick labels.

Update: Red was able to help with the tick label size, as well as correctly hiding the z-axis. Lastly, the ticks on the y-axis were suppressed. The complete solution is included in my code.

  1. Leave the z-axis in and the labels are too big. See the left image.
  2. Remove the z-axis and all labels go away, which is not what I need either. Also, two strange, short lines appear toward the top of the graph when I remove the z-axis. See the right image.

Here is an image of the correct solution. (Note: Made irrelevant adjustments to the square size.)

Best Answer

You can add every axis/.append style={font=\tiny}, before every axis x label/.style. In this way you don't need to use \tiny in x-y-z-labels.

To hide z axis just add hide z axis, after axis z line=center. I believe that if you put only axis z line=none you are hiding only the axis line but not the ticks that are the short lines in your image. They are in that position because with axis z line=none the z-axis is no more centered.

\pgfplotsset{
  compat=newest, % Allows drawing of circles.
  standard/.style={
    axis equal,
    axis line style=help lines,
    axis x line=center,
    axis y line=center,
    axis z line=center,
    hide z axis,
every axis/.append style={font=\tiny},
    every axis x label/.append style={
      at={(axis cs:\pgfkeysvalueof{/pgfplots/xmax},0,0)},xshift=0.5em},
    every axis y label/.append style={
      at={(axis cs:0,\pgfkeysvalueof{/pgfplots/ymax},0)},yshift=0.7em},
    every axis z label/.append style={
      at={(axis cs:0,0,\pgfkeysvalueof{/pgfplots/zmax})},xshift=0.5em}
  }
}
