title: Grisu not defined - Julia
body: <p>I have just started to use Julia a few days back.
  While trying to plot, I am getting the following error:</p>
  <pre><code>using Plots
  x = 1:10; y = rand(10); # These are the plotting data
  plot(x, y)
  </code></pre>
  <p>ERROR:</p>
  <pre><code>UndefVarError: Grisu not defined

  <p>Googles it for a few hours. Saw some similar queries but couldn't find a satisfactory solution. Have got both Plot and Grisu packages installed.</p>
