title: Log scale (x axis) histogram
body: <p>what I need is a histogram with X axis displayed on a log scale. However, I still want every bar in a histogram to be of the same width.</p>
  
  <p>Whatever, I came up with (or upon) display bars with higher values as narrower ones (they are of the same width on ordinary scale and not on log scale).</p>
  
  <p>Here is what I am doing now:</p>
  
  <pre><code>edges = 10.^(c_min:0.1:c_max); 
  h = histc(data, edges);
  bar(edges, h); set(gca, 'Xscale', 'log');
  </code></pre>
