Bar chart single series issue

paragp / achartengine

AChartEngine is a charting library for Android applications. It currently supports the following chart types: line chart area chart scatter chart time chart bar chart pie chart bubble chart doughnut chart range (high-low) bar chart dial chart / gauge combined (any combination of line, cubic line, scatter, bar, range bar, bubble) chart cubic line chart All the above supported chart types can contain multiple series, can be displayed with the X axis horizontally (default) or vertically and support many other custom features. The charts can be built as a view that can be added to a view group or as an intent, such as it can be used to start an activity. The model and the graphing code is well optimized such as it can handle and display huge number of values. AChartEngine is currently at the 1.0.0 release. New chart types will be added in the following releases. Please keep sending your feedback such as we can continually improve this library.

In trying to create a bar chart with single series, an exception occurs using 
the current version of ACE "1.0.0". Please refer to previous issue #9.

Modifying the "StackedSalesChart" demo to include only one series created this 
exception (see below).

  public Intent execute(Context context) {
///    String[] titles = new String[] { "2008", "2007" };
    String[] titles = new String[] { "2008" };
    List<double[]> values = new ArrayList<double[]>();
///    values.add(new double[] { 14230, 12300, 14240, 15244, 15900, 19200, 
22030, 21200, 19500, 15500,
///        12600, 14000 });
    values.add(new double[] { 5230, 7300, 9240, 10540, 7900, 9200, 12030, 11200, 9500, 10500,
        11600, 13500 });
    int[] colors = new int[] { Color.BLUE, Color.CYAN };
    XYMultipleSeriesRenderer renderer = buildBarRenderer(colors);
    setChartSettings(renderer, "Monthly sales in the last 2 years", "Month", "Units sold", 0.5,
        12.5, 0, 24000, Color.GRAY, Color.LTGRAY);
    renderer.getSeriesRendererAt(0).setDisplayChartValues(true);
    renderer.getSeriesRendererAt(1).setDisplayChartValues(true);
    renderer.setXLabels(12);
    renderer.setYLabels(10);
    renderer.setXLabelsAlign(Align.LEFT);
    renderer.setYLabelsAlign(Align.LEFT);
    renderer.setPanEnabled(true, false);
    // renderer.setZoomEnabled(false);
    renderer.setZoomRate(1.1f);
    renderer.setBarSpacing(0.5f);
    return ChartFactory.getBarChartIntent(context, buildBarDataset(titles, values), renderer,
        Type.STACKED);
  }
