Months displayed incorrectly when using ggplot2
<p>Hi having a problem where March appears twice in my graph but not in my Data. </p>

<p>My data looks like. My data frame is called try1.</p>

<pre><code>    Month                 Year    tcol
   2016-01-01 00:00:00    06      1461.0
   2016-02-01 00:00:00    06      259.5
   2016-03-01 00:00:00    06      191.2
   2016-04-01 01:00:00    06      151.5
   2016-05-01 01:00:00    06      119.6
   2016-06-01 01:00:00    06      1372.5
   2016-07-01 01:00:00    06      954.0
   2016-08-01 01:00:00    06      1784.0
   2016-09-01 01:00:00    06      1369.0
   2016-10-01 01:00:00    06      6077.0
   2016-11-01 00:00:00    06      1638.0
   2016-12-01 00:00:00    06      3308.0
</code></pre>

<p>And my code looks like.</p>

<pre><code>ggplot(try1, aes(Month,tcol)) + 
       geom_point(aes(colour = Year),size=2) + 
       geom_line(aes(colour = Year), size=0.73)+
       theme_bw()+
       guides(col = guide_legend(ncol = 2))+
       scale_x_datetime(
                        breaks=date_breaks("1 months"), 
                        labels=date_format("%B"))+
       xlab("")+ #x axis label 
       ylab("Total Coliforms")
</code></pre>

<p>The problem is that when I plot my graph March appears twice. And October appears to be left out. </p>
