title: Set the limits for the y-axis on rCharts
body: <p>How can I set the limits for a "multiBarChart" plot produced by "rCharts". For example I want that the values of the y-axis are between 1 and 10.</p>
  
  <pre><code>data&lt;-data.frame(Var=c(1,2,3,4),
                   Fac1=rep(c("A","B"),2),
                   Fac2=rep(c("Blue","Red"),each=2))
  
  require(rCharts)    
  
  n1 &lt;- nPlot(Var~Fac2, group = "Fac1", data = data, type = "multiBarChart")
  n1
  </code></pre>
