title: Rectangle Scatter Plot with axis type datetime in Bokeh
body: <h1>Rectangle Scatter Plot with axis type datetime in Bokeh</h1>
  
  <p>I would like to create a plot with the x-axis type <code>datetime</code>. As an example I used the function <code>scatter</code> with squares and the visual variable size.</p>
  
  <pre><code>import datetime
  from bokeh.plotting import *
  
  figure(x_axis_type="datetime")
  scatter([d1,d2,d3], [1,5,3], size=[10,20,30], marker="square")
  show()
  </code></pre>
  
  <p>As a second visualization I would replace the square with a rectangle and use the visual variables width and height. Because of the unit division I can not see the width. Is there a solution for this problem (except multiply the width with a factor)? Can I create a new marker?</p>
  
  <pre><code>figure(x_axis_type="datetime")
  rect([d1,d2,d3], [1,5,3], [1,2,3], [5,1,2])
  show()
  </code></pre>
  
  <p>NOTE: I'm using <code>Python v.2.7.8</code> and <code>Bokeh v.0.7.0</code>.</p>
