title: Log axis appearance in julia/Plots
body: <p>Here is a plot generated by julia's Plots library, using the <code>xaxis=:log</code> attribute:</p>

  <p>The plot has evenly spaced tick marks, with labels like 10^0.25. This might be useful sometimes, but I find it a bit confusing for this plot, because most people don't know the value of 10^0.25 without looking it up. </p>
  
  <p>I would prefer the x axis to have logarithmically spaced ticks, representing uniform intervals of the quantity on the x axis. Here's a quick example to show what I mean, generated using <code>semilogx</code> in Python's <code>matplotlib</code> lirary:</p>

  <p>In this plot the x axis has ticks at x=1, x=2, x=3 etc., which I find more useful for the figures I'm generating. Can this be achieved in julia using Plots?</p>
