title: plotting bar graph from pair of values from list of arrays
body: <p>I have a list of arrays each with 1 row and 2 cols (<code>list=array([1.3, 4.5]), array([1.4, 6.8]), array([2.5, 2.88]</code>).</p>
  <p>I want to plot bar graph, where each col values of each array(say they are <code>array([x, y]</code>) are plotted side by side, x has same color for all values and y has same color for all values.</p>
  <p>How can I go about it?</p>
  <p>like this:</p>
