title: in R ggplot how to change labels for multiple barplots
body: <p>I am trying to change the label of a multi-variable plot in ggplot
  My first image is this:
  <a href="https://i.stack.imgur.com/n9jhw.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/n9jhw.png" alt="enter image description here"></a></p>
  
  <p>The first image shows that I have two variables - Count and Total Gross
  And I have x labels as G and N (which are the variable values I have in the data)
  I want to change the x-labels to be more descriptive </p>
  
  <p>how can I update my ggplot statement to introduce these new labels</p>
  
  <pre><code> test %&gt;%
     group_by(DiscInd) %&gt;% 
     summarise(Count=n(),TotalGross=sum(Gross)/100000000) %&gt;% 
     gather(Var, Val, -DiscInd) %&gt;% 
     ggplot(., aes(x=DiscInd, y = Val, fill=Var)) +
          geom_bar(stat="identity", position="dodge") +
      xlab("Year vs Released Difference") + 
      ylab("Total Gross")                 +
      ggtitle("Total Movie with Gross ")  
  </code></pre>
  
  <p>Is this possible?</p>
  
  <p>Here are some records for my dataframe test</p>
  
  <pre><code>        DiscInd      Gross
            N        2783918982
            N        2207615668
            N        1670328025
            N        1519479547
            G        1514019071
            G        1404705868
  </code></pre>
  
  <p>UPDATED:
  Also I am trying to change labels and formatting labels so that it does not overlap each other. </p>
