title: Jfreechart: Can SymbolAxis work with TimeSeriesChart?
body: <p>Currently I am using JfreeChart to create dynamic charts. Now am facing problem with XY chart. I want show some fixed string label names on Y axis and same time X axis have to fix with dynamic Date time values. How would I customize the X axis and Y axis.
  Here I have tried using TimeSeriesChart. Sample code here</p>
  
  <pre><code>    TimeSeries s1 = new TimeSeries("Encounter Summary");
      s1.add(new Year(2001), 181.8);
      s1.add(new Year(2002), 167.3);
      TimeSeriesCollection timeset = new TimeSeriesCollection();
      timeset.addSeries(s1);
      JFreeChart chart = ChartFactory.createTimeSeriesChart("Encounter Summary","Words",  "Activation", timeset, true,true,false);
      XYPlot plot = (XYPlot) chart.getPlot();
      String[] months =  new String[2];
      months[0] = "Jan";
      months[1] = "Feb";
      SymbolAxis rangeAxis = new SymbolAxis("Activation", months);
      rangeAxis.setTickUnit(new NumberTickUnit(1));
      rangeAxis.setRange(0,months.length);
      plot.setRangeAxis(rangeAxis);
  </code></pre>
  
  <p>When I tried above code i am able to see chart but not showing data line points in chart, When I commented SymbolAxis part its showing data points.
  I am suspecting SymbolAxis is not working with TimeSeries. When i used <strong>createXYLineChart</strong> instead of <strong>createTimeSeriesChart</strong> then succesfully showing data axis points in chart. Please help me to solve this problem. </p>
  
  <p>Actually my requirement is Y axis fixed with month names Jan,Feb,Mar,Apr..Dec and same time X axis have to show dynamic data time values. Please refer below image.</p>
