title: Change errorbar size
body: <p>I have to change the size of the markers in my plot (making them bigger). How is it possible to change the width of errorbars too? I'm using <code>matplotlib</code>. Thanks.</p>
  
  <pre><code>plot=ax.errorbar(x,y, yerr=[y1,y2], color='red', fmt='.', markersize='10', ecolor='red',capsize=4)
  </code></pre>
