title: Highcharts scatter plot. Bad working 'hover' of points near the edge of plot
body: <p>When scatter points placed on the edge of plot, 'hover' event triggered only when mouse is over a part of the point in the plot area. With small markers the user has to 'hunt for pixels' for tooltip.
  Here is the sample:
  <a href="http://jsfiddle.net/Efm4p/4/" rel="nofollow">http://jsfiddle.net/Efm4p/4/</a></p>
  
  <pre><code>$(function () {
  var chart;
  
  $(document).ready(function() {
      chart = new Highcharts.Chart({
          chart: {
              renderTo: 'container',
              type: 'scatter',
          },
          xAxis:{
              min:0,
              max: 100},
          yAxis:{
              min:0,
              max:2,
              tickInterval:1,
              lineWidth:1
          },
          series: [{
              marker:{
                  lineWidth:1,
                  lineColor:'BBBBBB',
                  radius:3
              },
              data: [{x: 10, y: 2}, {x: 0.5, y:1}, {x: 0, y: 1}, {x: 12, y: 2}, {x: 11, y: 2}]
          }]
      });
  });  
  
  });
  </code></pre>
  
  <p>In this example very hard to get a tooltip for point {x: 0, y: 1}.</p>
  
  <p>I'm trying to set minPadding/maxPadding for axis, but they don't work when I set min/max clearly.
  It is important to set min/max explicitly, because a real chart shows % form 0 to 100 by x-axis and categories by y-axis. Some of points have a 0% or 100% values by x-axis and belong for first or last category by y-axis.</p>
  
  <p><b>Upd:</b> My question is "How to make 'hover' working normal for points, placed on the edge of the plot?"</p>
