How to Display AChartEngine bar chart properly

Following your numbering scheme:

  1. You can fix this by setting the X axis min and max of the visible area: mRenderer.setXAxisMin(min); and mRenderer.setXAxisMax(max);
  2. You can reduce it by increasing the width or by using the above methods such as there is more space to the left and right.
  3. There is an opened issue for this.
  4. Try mRenderer.setXLabelsColor(color);
  5. renderer.setChartValuesTextSize(size);
  6. mRenderer.setXLabels(0);

Edit:

  1. Use renderer.setChartValuesTextSize(size);
  2. Same as #1.
  3. mRenderer.setYAxisMax(300);
  4. Known issue: http://code.google.com/p/achartengine/issues/detail?id=312

I discovered that sizes are not correctly density calculated.

If u want:

mRenderer.setLabelsTextSize(15); 
mRenderer.setLegendTextSize(15);

You need to set:

mRenderer.setLabelsTextSize(15* getResources().getDisplayMetrics().density); 
mRenderer.setLegendTextSize(15* getResources().getDisplayMetrics().density);

I encounter the same problem. This is because AChartegine is trying to allocate enough space for each renderer so make a shift. This should simply resolved by Type.STACKED

Change

ChartFactory.getBarChartView(context, dataset,mRenderer, Type.DEFAULT);

to

ChartFactory.getBarChartView(context, dataset,mRenderer, Type.STACKED);

Hope this helps!

   GraphicalView mChart = createIntent();
   layout_graph.addView(mChart);



public GraphicalView createIntent() {

        String[] titles = new String[] { " " };

        List<Double> values = new ArrayList<Double>();




        for (int i = 0; i < yaxes_value.size(); i++) {
//          values.add(Double.parseDouble(yaxes_value.get(i)));


        }


        int[] colors = new int[] { Color.parseColor("#4DBA7A") };
        XYMultipleSeriesRenderer renderer = buildBarRenderer(colors);
        setChartSettings(renderer, "Simple Bar Chart", X_title, Y_title+type,

        for (int i = 0; i < Xaxes_value.size(); i++) {
