Strange line in androidplot

Question

I'm create my androidplot bar chart but I have problem with strange line in start of domain axis. You can see it on the screen

How can I remove it? Here is my code:

layout:

<?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

This is because of

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

if will remove it, it will be gone.Actually this is graph grid line which is moved .
