title: X-axis goes farther than last time interval
body: <p>If I set a time interval, <code>[0 10]</code>, and I plot something according to that time interval, <code>plot(t, y())</code>, then the graph will have its x-axis going all the way to 11. </p>
  
  <p>It used to not do this. It used to produced a better fitting graph, but now it produces a graph with white space attached to the end of the graph between points 10 and 11. </p>
  
  <p>I must have accidentally changed a setting. How do I get the plot function to best fit the graph?</p>
