title: Plot multiple columns with geom_bar()
body: <p>I recently started programming in R and I am trying to plot several columns using ggplot2.</p>
  
  <p>My data frame looks like this: </p>
  
  <pre><code>mydf &lt;- data.frame(Names, Less, Equal, More)
  mydf
  
      Names Less Equal More
  1   Sarah    8    25    8
  2   Mark    13    13   13
  3   Peter   11    26    5
  </code></pre>
  
  <p>And to give an idea of how I created this data frame, 'Less' looks like this:</p>
  
  <pre><code>[1]  8 13 11
  </code></pre>
  
  <p>I want to be able to compare for every name if their scores are less, equal, or more. On the x-axis, I actually want to plot "More", "Less", and "Equal", with different bars for each name. On the y-axis I want to print the score (e.g. 8, 25...). I want to create multiple bars for each name.</p>
  
  <p>I have tried several things, but I have only succeeded in adding a single value on the y-axis:</p>
  
  <pre><code>test &lt;- ggplot(mydf, aes(x= Names, y= More)) +
  geom_bar(stat = "identity") 
  </code></pre>
  
  <p>I have a feeling that the problem lies with the way my data is organised, but I am not sure.</p>
