Bar chart - if there is only one category the bars widht is thin.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. In GeneratedChartDemo Class XYMultipleSeriesDataset  final int nr = 1;
2.
3.

What is the expected output? What do you see instead?
The bars should be of same with even if their is only one category

Please provide a source code snippet that we can use to replicate the issue.
In GeneratedChartDemo Class

 private XYMultipleSeriesDataset getDemoDataset() {
    XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
    final int nr = 10;
    Random r = new Random();
    for (int i = 0; i < SERIES_NR; i++) {
      XYSeries series = new XYSeries("Demo series " + (i + 1));
      for (int k = 0; k < nr; k++) {
        series.add(k, 20 + r.nextInt() % 100);
      }
      dataset.addSeries(series);
    }
    return dataset;
  }

What version of the product binary library are you using?
recent one 1.1

Please provide any additional information below.
i had looked into the source code i see that its because of calling this method 
getHalfDiffX(points, length, seriesNr); in drawSeries method and i see that its 
because in getHalfDiffX method
your are setting if (halfDiffX == 0) {
      halfDiffX = 10;
    }

Please let me know how to fix this

Please change the final int nr = 10; to final int nr = 1; to see the output 
with bars having thin width

I added a new method for setting a constant bar width in pixels.

renderer.setBarWidth(100);
