title: highcharts transparent series
body: <p>I'm drawing a line chart with two series, one of them being transparent (but with colored points).</p>
  
  <p>My problem is that the transparent series doesn't have a color in the legend, and it doesn't look good (especially when hiding it by clicking its name in the legend).</p>
  
  <p>Here's an example of what I'm doing:
  <a href="http://jsfiddle.net/topatidle/G4NLn/" rel="nofollow">JSFiddle Example</a></p>
  
  <p>The code that creates the transparent series is:</p>
  
  <pre><code>{type:'spline',name:'Transparent',color:'rgba(255, 255, 255, 0.1)', data:[{x:1361059200000, y:0.0, marker: {symbol: "square", radius: 3, fillColor: "#f2a8a8", states: { hover: {radius: 3, fillColor: "#f2a8a8"}}}},{x:1361088000000, y:0.0, marker: {symbol: "square", radius: 8, fillColor: "#f2a8a8", states: { hover: {radius: 8, fillColor: "#f2a8a8"}}}},{x:1361116800000, y:0.0, marker: {symbol: "square", radius: 6, fillColor: "#f2a8a8", states: { hover: {radius: 6, fillColor: "#f2a8a8"}}}}]}
  </code></pre>
  
  <p>Is there a way to set a color to the series legend (either during chart creation or with JavaScript after the chart was created)?</p>
  
  <p>Thanks,
  Ziv</p>
