Multiple Color bars for single series and single renderer

Question

I am generating a bar chart graph for the Single series and single renderer. I need the bars to be generated with different colors according to my given data condition.

Following is my code for Renderer,

  private XYMultipleSeriesRenderer getDemoRenderer() {
    XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer();
    renderer.setBarSpacing(1.0);
    renderer.setAxisTitleTextSize(12);
    renderer.setChartTitleTextSize(12);
    renderer.setLabelsTextSize(15);
    renderer.setLegendTextSize(15);
    renderer.setPointSize(5f);
    renderer.setMargins(new int[] { 20, 30, 15, 0 });
    renderer.setXLabels(0);
    XYSeriesRenderer r = new XYSeriesRenderer();
    SQLiteDatabase DB = Context
            .openOrCreateDatabase("WaterElectricityReadingDataBase.db",
                    MODE_WORLD_READABLE, null);
    Cursor c = DB
            .rawQuery(
                    "select ReadingValue,ReadingMode, from WaterElectricity ",
                    null);  
    if (c.moveToFirst()) {
        do {
            String ReadingMode = c.getString(c
                    .getColumnIndex("ReadingMode"));
            if (ReadingMode.contains("Water")){

                r.setColor(Color.GREEN);
            }else if(ReadingMode.contains("Electricity")){
                r.setColor(Color.WHITE);
            }
        }while (c.moveToNext());
    }              
    r.setPointStyle(PointStyle.DIAMOND);
    r.setFillBelowLine(false);
    r.setFillPoints(true);
    renderer.addSeriesRenderer(r);
    setChartSettings(renderer);
    return renderer;
}

In the above code if the ReadingMode is "Water" I need the bar to generated in Green color and for the other, in white color. If I run the above code, I did observe that all bars are generated in green color. I am having records with ReadingMode as "Water" and "Electricity" in my database. But why is this happeing? Do I need to take multiple renderers but I am having single series?

Can any one suggest me the good solution? My head is about to break.

Any help will be appreciated!! Thanks in advance!!

Solved for My self. Taken two series with two renderers. That solved the Issue. — Mahe, Mar 27 '13 at 06:07

Bar chart using achartengine. Check the accepted answer in the link.

OR

Use a Different series for each bar.

http://code.google.com/p/achartengine/issues/detail?id=76. Some one reported an issue regarding the same.
