androidplot奇怪的線

Question

我創建了我的androidplot條形圖，但我有域軸啓動奇怪的行的問題。你可以看到它的屏幕

如何刪除它？這裏是我的代碼：

佈局：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" > 

    <com.androidplot.xy.XYPlot 
      android:id="@+id/barPlot" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent" 
      androidPlot.titleWidget.labelPaint.textSize="@dimen/title_font_size" 
      androidPlot.rangeLabelWidget.labelPaint.textSize="@dimen/range_label_font_size" 
      androidPlot.graphWidget.marginTop="5dp" 
      androidPlot.graphWidget.marginLeft="35dp" 
      androidPlot.graphWidget.marginBottom="5dp" 
      androidPlot.graphWidget.marginRight="5dp" 
      androidPlot.graphWidget.gridBackgroundPaint.color="#FFFFFF" 
      androidPlot.graphWidget.rangeLabelPaint.textSize="@dimen/range_tick_label_font_size" 
      android:layout_weight="1" 
      androidPlot.graphWidget.gridLinePaint.color="#000000"/> 

</LinearLayout>

Answer 1

這是因爲

plot.getGraphWidget().setGridPadding(30, 10, 30, 0); 

，如果將其刪除，這將是gone.Actually這是移動的圖形網格線。
