title: How to plot multiple boxplots in one chart?
body: <p>I have this subset which I want multiple boxplot, for each column (ggplot)</p>
  <pre><code>  Q006 NU_NOTA_CN NU_NOTA_CH NU_NOTA_MT NU_NOTA_LC NU_NOTA_REDACAO
  1    B      435.6      512.3      432.4      488.6             420
  2    B         NA      409.3         NA      375.3             400
  3    B      426.2      578.1      499.9      551.5             500
  4    B      489.8      534.3      406.7      527.5             680
  5    B         NA         NA         NA         NA              NA
  6    B         NA         NA         NA         NA              NA
  </code></pre>
  <p>My goal is similar to this&gt; Instead A,B,C... in x axis, I want the NU_NOTA_CN, NU_NOTA_CH, NU_NOTA_MT, NU_NOTA_LC, NU_NOTA_REDACAO</p>
