AchartEngine折线图Xaxis Android
我在Android上工作achartengine并完成所有作品我在线图中遇到一个问题我提到了xaxis标签，但它的显示像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，请参见下图：
这是完整的代码：
public class ChartExample extends Activity {
private GraphicalView mChartView;
XYMultipleSeriesRenderer renderer;

最后我得到了解决方案，我在下面尝试了以下代码：
renderer.setXLabels(0);

答案 1 :(得分：-1)
您需要添加到当前代码的唯一代码是以下两行：
renderer.setXLabels(RESULT_OK);
renderer.clearXTextLabels();
确保在声明渲染器设置后添加这些声明，但之前设置自定义X轴文本标签的代码。
由于程序中有多个渲染器方法，因此应在实现XYMultipleSeriesRenderer的方法末尾包含这两行代码。同样，请确保在实现自定义文本标签之前在代码中添加此项。 ：）
