title: Scatter plot and boxplot overlay
body: <p>Based on the previous post <a href="https://stackoverflow.com/questions/14707952/ggplot-boxplots-with-scatterplot-overlay-same-variables">ggplot boxplots with scatterplot overlay (same variables)</a>, <br/></p>
  
  <p>I would like to have <strong>one boxplot for each day of week</strong> instead of two boxplots <strong>while have scatter points on it with different colour.</strong></p>
  
  <p>The code will be like:</p>
  
  <pre><code>#Box-plot for day of week effect
  plot1&lt;-ggplot(data=dodgers, aes(x=ordered_day_of_week, y=Attend)) + geom_boxplot()
  
  #Scatter with specific colors for day of week
  plot2&lt;-ggplot(dodgers, aes(x=ordered_month, y=Attend, colour=Bobblehead, size=1.5)) + geom_point()
  
  #Box-ploy with Scatter plot overlay
  plot3&lt;-ggplot(data=dodgers, aes(x=ordered_day_of_week, y=Attend, colour=Bobblehead)) + geom_boxplot() + geom_point()
  </code></pre>
  
  <p>And the result would be: <br/>
  1, scatter plot</p>
