AchartEngine Xaxis Android line chart

Question

I work with achartengine on android and have done all the work. I have one problem in a line chart. I mention the xaxis shortcut, but it shows as 2,4,6,8,10,12 and so on with overlay with my xaxis label and I want to hide 2,4,6,8,10,12 shortcuts in xaxis. if I don’t understand, see the picture below:

here is the full code:

public class ChartExample extends Activity { private GraphicalView mChartView; XYMultipleSeriesRenderer renderer; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.layout_chart); LinearLayout layout = (LinearLayout) findViewById(R.id.linearLayout2); String[] titles = new String[] { "spens1","2second" }; List<double[]> x = new ArrayList<double[]>(); x.add(new double[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 }); x.add(new double[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 }); // } List<double[]> values = new ArrayList<double[]>(); values.add(new double[] { 9, 10, 11, 15, 19, 23, 26, 25, 22, 18, 13, 10 }); values.add(new double[] { 11, 13, 21, 10, 40, 10, 12,15, 24, 20, 15, 12 }); int[] colors = new int[] { Color.BLUE,Color.RED}; PointStyle[] styles = new PointStyle[] { PointStyle.CIRCLE,PointStyle.CIRCLE}; renderer = buildRenderer(colors, styles); int length = renderer.getSeriesRendererCount(); for (int i = 0; i < length; i++) { ((XYSeriesRenderer) renderer.getSeriesRendererAt(i)) .setFillPoints(true); } setChartSettings(renderer, "SCORE CARD VIEW", "Attetempts", "Marks Scored", 0, 12.5, 0, 45, Color.LTGRAY, Color.LTGRAY); renderer.setXLabels(12); renderer.setYLabels(10); renderer.setShowGrid(false); renderer.setXLabelsAlign(Align.CENTER); renderer.setYLabelsAlign(Align.CENTER); //renderer.setZoomButtonsVisible(true); //renderer.setPanLimits(new double[] { 0, 20, 0, 40 }); //renderer.setZoomLimits(new double[] { 0, 20, 0, 40 }); renderer.setPanEnabled(false, false); renderer.setZoomEnabled(false, false); renderer.setShowLegend(false); for(int k=0;k<12;k++) { renderer.addXTextLabel(k+1,"test"); } if (mChartView == null) { Log.d("Oncreate ", "if (mChartView == null)"); mChartView = ChartFactory.getLineChartView(this, mDataset(titles, x, values), renderer); layout.addView(mChartView, new LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); } else { mChartView.repaint(); Log.d("Oncreate ", "if (mChartView != null)"); } } private void setChartSettings(XYMultipleSeriesRenderer renderer3, String title, String xTitle, String yTitle, double xMin, double xMax, double yMin, double yMax, int axesColor, int labelsColor) { // TODO Auto-generated method stub renderer3.setChartTitle(title); renderer3.setXTitle(xTitle); renderer3.setYTitle(yTitle); renderer3.setXAxisMin(xMin); renderer3.setXAxisMax(xMax); renderer3.setYAxisMin(yMin); renderer3.setYAxisMax(yMax); renderer3.setAxesColor(axesColor); renderer3.setLabelsColor(labelsColor); } private XYMultipleSeriesRenderer buildRenderer(int[] colors, PointStyle[] styles) { // TODO Auto-generated method stub XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer(); setRenderer(renderer, colors, styles); return renderer; } private void setRenderer(XYMultipleSeriesRenderer renderer2, int[] colors, PointStyle[] styles) { // TODO Auto-generated method stub renderer2.setAxisTitleTextSize(16); renderer2.setChartTitleTextSize(20); renderer2.setLabelsTextSize(15); renderer2.setLegendTextSize(15); renderer2.setPointSize(5f); renderer2.setMargins(new int[] { 20, 30, 15, 20 }); int length = colors.length; for (int i = 0; i < length; i++) { XYSeriesRenderer r = new XYSeriesRenderer(); r.setColor(colors[i]); r.setPointStyle(styles[i]); renderer2.addSeriesRenderer(r); } } private XYMultipleSeriesDataset mDataset(String[] titles, List<double[]> xValues, List<double[]> yValues) { // TODO Auto-generated method stub XYMultipleSeriesDataset dataset1 = new XYMultipleSeriesDataset(); addXYSeries(dataset1, titles, xValues, yValues, 0); return dataset1; } private void addXYSeries(XYMultipleSeriesDataset dataset, String[] titles, List<double[]> xValues, List<double[]> yValues, int scale) { // TODO Auto-generated method stub int length = titles.length; for (int i = 0; i < length; i++) { double[] xV = xValues.get(i); XYSeries series = new XYSeries(titles[i], scale); double[] yV = yValues.get(i); int seriesLength = xV.length; for (int k = 0; k < seriesLength; k++) { series.add(xV[k], yV[k]); } dataset.addSeries(series); } } } 

You can help me with a great estimate.

Finally, I got the solution, I tried this code below:

 renderer.setXLabels(0); 

and the full class code:

Answer 2

The only code that needs to be added to the current code is the following two lines:

 renderer.setXLabels(RESULT_OK); renderer.clearXTextLabels(); 

Be sure to add these instructions after declaring the rendering options, but BEFORE where you set your custom text labels along the X axis.

Since there are several rendering methods in your program, you must include these two lines of code at the end of your methods that implement the XYMultipleSeriesRenderer. Again, be sure to add this to your code before embedding your custom text labels. :)
