title: How to plot an error bar plot with standard deviation values in MATLAB?
body: <p>I am very new to <a href="http://en.wikipedia.org/wiki/MATLAB" rel="nofollow">MATLAB</a> and expect a step-by-step solution. I have data, <code>series(y)</code>, which I have to plot against <code>(x)</code>. Also I have the standard deviation values for each data point of <code>(y)</code>. Now I have to plot these series highlighting the error bars. How can I do that?</p>
  
  <p>The data is in a text file sorted in columns as:</p>
  
  <pre><code>X = -50, -49, -48, -47....0....1, 2, 3, 4, 5....till 50
  
  Y = 1.2, 1.0, 1.1, 1.9, 1.3.....
  </code></pre>
  
  <p>Standard deviation <code>= 0.6, 0.5, 0.3, 0.6, 0.6.....</code></p>
  
  <p>Also, how do I control the ticks and appearance property for these kinds of graphs?</p>
