title: How can I rotate the axis label in Julia plots?
body: <p>I'm trying to rotate the y axis label of a plot:</p>
  <pre><code>function contour(k::Real, a::Real = 6.0, y::Real = 12.0)
      y^2 / ((a^2) * k)
  end
  
  K_contour = range(0.5, stop = 8, length = 1000)
  
  plot(K_contour, contour, xaxis = (&quot;K&quot;, (0, 8)),
                           yaxis = (&quot;L&quot;, (0,8)),
                           label = &quot;&quot;, 
                           )
  </code></pre>
  <p>I get the following:<a href="https://i.stack.imgur.com/uzRHN.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/uzRHN.png" alt="enter image description here" /></a></p>
  <p>I'd like to rotate the &quot;L&quot; 90 degrees. I can't find the appropriate axis attribute for this - can anyone help?</p>
