AchartEngine折线图Xaxis Android

Question

我工作在Android上的achartengine，并完成了所有工作，我有一个问题，我在线图我提到xaxis标签，但它的显示像2,4,6,8,10,12等等用我的xaxis标签覆盖，我想隐藏2,4,6,8,10,12个xaxis标签。如果你不明白看给出如下图所示：

这里是全码：

我终于得到了解决，我有以下试试这个代码：

renderer.setXLabels(0);

你需要添加到您当前密码的唯一代码是以下两个行：

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

请确保在声明您的渲染器设置后添加这些语句，但之前您设置您的自定义X轴文本标签的代码。

由于您的程序中有多个呈现器方法正在进行，因此您应该在实现XYMultipleSeriesRenderer的方法末尾包含这两行代码。再次，确保在实现自定义文本标签之前将其添加到代码中。 :)
