title: Rstudio reorder stacked ggplot geom_bar
body: <p>So I've made a stacked Barplot with help of @Axeman . So far so good.. Now I would love to swap the Blue plot with the Red plot. I've literally tried everything using the order function in ggplot and I cant get it right. Here is the Plot:   </p>

  <p>Below, you can find an extract of the dataframe that was used for this plot (first row containts the header). Basically its a division name, followed by two types of savings (Repetitive and MDF) and the the last column contains the sum of both (NewRepetitive + Anrechenbare_MDF)</p>

  </code></pre>
  
  <p>Here is the R-Code that was used to edit the dataframe the right way (using tidyr package), so I could make the stacked barplot, since ggplot needs the data in a specific form.</p>
  
  <pre><code>  library(ggplot2)
    library(tidyr) 
  
    pd &lt;- gather(stack, 'key', 'value', -DivisionName)
    pd &lt;- pd[pd$key != 'Total_CR', ]
  </code></pre>
  
  <p>And finally the ggplot code:</p>
  
  <pre><code>ggplot(pd, aes(DivisionName,  value, fill = key)) +
    geom_bar(stat = "summary", fun.y = "sum") +
    scale_fill_discrete(name="Saving-Typen",labels=c("MDF-Savings","Repetitive Savings")) +
    ylab("Total Savings") +  scale_y_continuous(breaks=c(seq(0,15000000,1000000)), expand = c(0,0))
  </code></pre>
  
  <p>The barplot looks exactly how I want it to, except the order.. I need to have the MDF Savings above of Repetitive-Savings. I'm sitting here for 5 hours and can't get the right solution.. I've tried everything with the "order" option. </p>
  
  <p>Can someone help me?</p>
