title: Relative size and scaling of points vs. axis text
body: <p>My question is related to the size of geometries and texts (in axes of a chart). I'm trying to export a chart with the size of the font must be approximately to 12 points, so I've declared <code>size = 12/.pt</code> in <code>element_text()</code>. To exemplify, I wrote the code:</p>
  <pre><code>library(ggplot2)
  
  chart = ggplot(diamonds)+
    geom_point(aes(x, price), size = 1, shape = &quot;circle open&quot;)+
    theme(axis.title = element_text(size = 12/.pt),
          axis.text = element_text(size = 12/.pt))
  
  chart
  </code></pre>
  <p><img src="https://i.stack.imgur.com/N2XW9.png" alt="chart" /></p>
  <p>Since <code>ggplot2</code> works with millimeters in its units, if I understod, declaring <code>geom_point(size = 1)</code>, and <code>theme(axis.title / axis.text = element_text(size = 12/.pt))</code>, the size of the points should must be smaller than the text, right? Why is this not the case?</p>
