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.

What steps will reproduce the problem?
1.Create orizontal bar chart with some values

What is the expected output? What do you see instead?
-The espected output is a bar chart shown correctly instead the bars overlap 
the value at their end.

-The code is exactly as in the sample app
The related code piece is:

String[] titles = new String[] { "2008", "2007" };
    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);
    ((XYSeriesRenderer) renderer.getSeriesRendererAt(0)).setDisplayChartValues(true);
    ((XYSeriesRenderer) 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);

What version of the product binary library are you using?
I'm using the latest night build 1.2.0

Please provide any additional information below.

-See the attachment. In addition there is a similar problem with the points in 
line charts, if you set a slightly bigger size for the point there is no way to 
set a margin between the point and its value label and the point overlap its 
value.
