title: Drawing an SVG Raphael path gives error and doesn't accept variables
body: <p>I'm trying to make a simple X axis for a chart using Raphael SVG path, but the variables for <code>M(moveto)</code> and <code>L(lineto)</code> aren't getting accepted.</p>
  
  <pre><code>var x1 = x,
      y1 = y+height,
      x2 = x+width,
      y2 = y+height;
  var xAxis = SVGpaper.path("Mx1,y1 Lx2,y2").attr({stroke: "config.axisColor", "stroke-width": 1});
  </code></pre>
  
  <p>It gives the error:</p>
  
  <p>Error: Problem parsing <code>d="M,0,0"</code></p>
  
  <p>Am I making some error in declaring the variables or in the syntax for path? I can't find any code to refer to, so please advice some tips!</p>
