title: How to plot asymnmetric errors with errorbar
body: <p>I would like to create a plot like pages 15/16:</p>
  
  <p>comisef.eu/files/wps031.pdf</p>
  
  <p>The example below gets close but only allows for symmetric error bars:</p>

  <p>This example has asymmetric errorbars but only when plotted against the bar graph values
  <a href="https://stackoverflow.com/questions/7816663/bar-with-asymmetric-error-bounds-in-matlab">bar with asymmetric error bounds in Matlab</a></p>
  
  <p>Is it possible to have asymmetric errorbars like in the first example shown but without the need for the bar graph?</p>
  
  <p>Thanks Baz</p>
  
  <p>I also have a question where I try to achieve the same thing with boxplot but I'm not sure which (if indeed either of them can) can do it.</p>

  <pre><code>x = 1985:.05:2001; % x data
  grad_ = rand(1,length(x))*.3; % graduated stuff
  grad_2 = rand(1,length(x))*.3;
  grad_3= rand(1,length(x))*.3;
  h = subplot(1,3,1);
  
  errorbar(grad_,x,grad_2,grad_3,'o');
  axis(h, [0 0.6 1985 2001])
  set(h, 'Ytick', x(1):x(end), 'Xtick', 0:.15:.6, 'YDir','reverse', 'YGrid', 'on');
  xlabel('Gradient Search')
