title: Help with showing a simple graph using google chart
body: <p>I'm pulling my hair out on this problem.</p>
  
  <p>I would like to show a very simple vertical bar graph which will represent the amount of sales during a week. So the data it would be fed is:</p>
  
  <pre><code>Sunday: 200
  Monday : 50
  Tue: 500
  Wed: 300
  Thu: 145
  Fri: 0
  Sat: 976
  </code></pre>
  
  <p>This would only be for a single given week, and I want the graph to show the sales data between the days to compare them and see which day had the most number of sales, etc.</p>
  
  <p>Then I'll want two other similar graphs, one for monthly sales, e.g</p>
  
  <pre><code>January: 2000
  Feb: 1490
  ..
  December: 4553
  </code></pre>
  
  <p>And an yearly graph e.g:</p>
  
  <pre><code>2006: 20000
  ...
  2009 30000
  </code></pre>
  
  <p>Again the comparison will be just between the 7 days of the week, 12 months of the year, or 4-5 years.</p>
  
  <p>I need a url which can be used to create these graphs, where I can just hook in my own data and the rest of the stuff would work by itself. Out of the <a href="http://code.google.com/apis/chart/types.html" rel="nofollow noreferrer">chart types</a> I'd like to use 'Vertical bar graph' (code bvs).</p>
  
  <p>One thing which can be a problem is the 'encoding' of the graphs, google charts seems to want you to give it an encoding which means a range between 0-500 or 0-6950, but I have no way of knowing which encoding the sales amounts would fall into, they could either be very little sales or very much. </p>
