android - AchartEngine 折线图 Xaxis Android

Question

我在 android 上使用 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 标签但它显示像 2,4,6,8,10,12 等等与我的 xaxis 标签叠加我想在 xaxis 中隐藏 2、4、6、8、10、12 个标签。如果你不明白，请看下图:

完整代码如下:

public class ChartExample extends Activity {
    private GraphicalView mChartView;

    XYMultipleSeriesRenderer renderer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        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 });
        // }

        values.add(new double[] { 11, 13, 21, 10, 40, 10, 12,15, 24, 20, 15,

        }

        if (mChartView == null) 
        {
            Log.d("Oncreate ", "if (mChartView == null)");

            layout.addView(mChartView, new LayoutParams(
                    LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));




        } 
        else

    }

}

你能帮我吗，非常感谢。

最后我得到了解决方案，我尝试了下面的代码:

renderer.setXLabels(0);

和这里的完整类代码:
