title: Ploting and understanding face_wrap and multiplevariable graphs - ggplot
body: <p>I am a newbie on graphs and r and I got the exercise to analyse a dataset. I am willing to do a graph (facet_wrap?) from it, where I show the distribution of profits per month from different countries.
  I have a subset with 19 Countries, 12 Months and profit values! Something like (example):</p>
  <pre><code>Country   Month  Profit
  Brazil    Jan     50
  Brazil    fev     80
  Brazil    mar     15
  Austria   Jan     35
  Austria   fev     80
  Austria   mar     47
  France    Jan     21
  France    fev     66
  France    mar     15
  [...]
  Germany   Dez     40 
  </code></pre>
  <p>I have played a bit around with the graph but I am still struggling with understanding how does it work. So far I have:</p>
  <pre><code>test &lt;- ggplot(sub, aes(x=Month, y=Profit, fill= Profit))+
  geom_bar(stat='identity')+
  facet_wrap(~Country) +
  scale_fill_gradient(low = &quot;red&quot;, high = &quot;green&quot;, name = &quot;Profit grade&quot;, labels = comma) +
  scale_y_continuous(labels = function(x) format(x, scientific = FALSE))+
  theme_bw()
  </code></pre>
  <p>which comes like:
  <a href="https://i.stack.imgur.com/hs1c8.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/hs1c8.png" alt="enter image description here" /></a></p>
  <p>there are a few problems though that I cant understand.</p>
  <ol>
  <li>Why aren't all the bars starting from the same line? they are not straight, is it normal? or why is the X axis fluctuating? (check France for clear picture)</li>
  <li>How can I fill it correctly? On my graph when I use the function Fill, the shade happens throughout the bar and not between different pars (Which would make more sense). Could you explain what this filling (from the photo) could be meaning?</li>
  <li>Would there be another/better way to present such information? I was willing to try a line graph, such as those mountain graphs about economics used on TV, but I don't know how to do it. I tried some points but didn't make sense for me (or I did wrong haha)</li>
