Android - achartengine bar chart issues

I use achartengine to draw my chart in an android application and have 2 issues with bar chart.

1: values at top bar doesn't align center

2: width of bar too small when just 1 bar in chart

enter image description here

enter image description here

Here my code for setting chart

    GraphicalView mChart;
    // Creating an  XYSeries for Income
    XYSeries incomeSeries = new XYSeries("\n" + note);
    // Adding data to Series
    // Arraylist<String> althongtin include input data (some numbers character, eg: {125, 4356, 50000})
    for(int i=0;i<althongtin.size();i++){
        incomeSeries.add(i, Double.parseDouble(althongtin.get(i)));
    }

    // Creating a dataset to hold each series
    XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
    // Adding Income Series to the dataset
    dataset.addSeries(incomeSeries);
    XYSeriesRenderer incomeRenderer = new XYSeriesRenderer();

    incomeRenderer.setColor(color);
    incomeRenderer.setChartValuesTextSize(20);
    incomeRenderer.setFillPoints(true);
    incomeRenderer.setDisplayChartValues(true);
    incomeRenderer.setChartValuesTextAlign(Paint.Align.CENTER);

    XYMultipleSeriesRenderer multiRenderer = new XYMultipleSeriesRenderer();

    multiRenderer.setXLabels(0);
    multiRenderer.setChartTitle(ten);
    multiRenderer.setXTitle(cotx);
    multiRenderer.setYTitle(coty);
    multiRenderer.setYLabelsAlign(Paint.Align.LEFT);
    multiRenderer.setBarSpacing(1);
    multiRenderer.setBarWidth(50);

    multiRenderer.setYAxisMin(0);
    multiRenderer.setYAxisMax(max + (max/10));
    multiRenderer.setXAxisMin(-1);
    multiRenderer.setXAxisMax(althongtin.size() + 1);
    multiRenderer.setLabelsTextSize(15);
    multiRenderer.setLegendTextSize(20);
    multiRenderer.setAxisTitleTextSize(20);
    multiRenderer.setChartTitleTextSize(20);

    multiRenderer.setLabelsColor(Color.BLACK);
    multiRenderer.setAxesColor(Color.BLACK);
    multiRenderer.setApplyBackgroundColor(true);
    multiRenderer.setBackgroundColor(Color.TRANSPARENT);
    multiRenderer.setMarginsColor(Color.argb(0,255,255,255));
    multiRenderer.setXLabelsColor(Color.BLACK);
    multiRenderer.setYLabelsColor(0, Color.BLACK);

    multiRenderer.addSeriesRenderer(incomeRenderer);

    String[] types = new String[] {BarChart.TYPE};

    mChart = (GraphicalView) ChartFactory.getCombinedXYChartView(getBaseContext(), dataset, multiRenderer, types);

    multiRenderer.setClickEnabled(true);
    multiRenderer.setSelectableBuffer(10);

    chartLayout.addView(mChart);

Thanks.

Updated: the second issue is fixed by upgrade to achartengine 1.2.0. Thank yoou, Dan.

For the first issue, you may want to upgrade to the 1.2.0 nightly build.

For the second one, there is: renderer.setBarWidth(widthInPixels); as this is the solutions to set the bar width when there is one single item in the series.

why not using ChartFactory.getBarChartView instead of ChartFactory.getCombinedXYChartIntent ?

I think it will fix ur problem .
