【问题描述】：
我在 android 上工作 achartengine 并完成了所有工作我在折线图中遇到了一个问题我提到了 xaxis 标签，但它显示为 2、4、6、8、10、12 等等，并与我的 xaxis 标签叠加我想在 xaxis 中隐藏 2、4、6、8、10、12 个标签。不明白的请看下图：
这里是完整的代码：
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

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);
}
}
}
您能帮助我吗，非常感谢。
