让GraphWidget填充AndroidPlot中的整个View

Question

有没有办法让AndroidPlot XYPlot的图形填充整个视图而不填充？

我特别谈到左侧的空间，我在图像中标记为红色：

我的目标是将图形叠加在图像上，并使其与父视图边框齐平。我已经删除了我的XYPlot子类中的所有标签，通过将它们的Paint设置为null，它们将占用的空间仍然存在。

以下是我设置情节的方法：

public void setup() {
    this.setBackgroundPaint(null);
    setPlotMarginLeft(0);

    setRangeBoundaries(-2, 2, BoundaryMode.FIXED);
    setDomainBoundaries(0, HISTORY_SIZE, BoundaryMode.FIXED);


    XYGraphWidget g = getGraphWidget();

    g.setDomainLabelPaint(null);
    g.setRangeLabelPaint(null);
    g.setDomainOriginLabelPaint(null);
    g.setRangeOriginLabelPaint(null);
    g.setGridBackgroundPaint(null);
    g.setGridPaddingLeft(0);
    g.setGridPaddingRight(0);
    g.setMarginLeft(0);
    g.setBackgroundPaint(null);
    g.position(-0.5f, XLayoutStyle.RELATIVE_TO_RIGHT, 
            -0.5f, YLayoutStyle.RELATIVE_TO_BOTTOM,
            AnchorPosition.CENTER);
    g.setSize(new SizeMetrics(
            0, SizeLayoutType.FILL,
            0, SizeLayoutType.FILL));

    LayoutManager l = getLayoutManager();
    l.remove(this.getDomainLabelWidget());
    l.remove(this.getRangeLabelWidget());
    l.remove(getLegendWidget());

    mSeries = new SimpleXYSeries("Azimuth");
    mSeries.useImplicitXVals();
    addSeries(mSeries, new LineAndPointFormatter(Color.BLACK, null, null, null));

}

知道了，这是我用来设置Plot而没有任何边距，填充或标签的代码：

    XYGraphWidget g = getGraphWidget();

    g.setDomainLabelPaint(null);
    g.setRangeLabelPaint(null);
    g.setDomainOriginLabelPaint(null);
    g.setRangeOriginLabelPaint(null);
    g.setGridBackgroundPaint(null);
    g.setGridPaddingLeft(0);
    g.setGridPaddingRight(0);
    g.setMarginLeft(0);
    g.setBackgroundPaint(null);
    g.position(-0.5f, XLayoutStyle.RELATIVE_TO_RIGHT, 
            -0.5f, YLayoutStyle.RELATIVE_TO_BOTTOM,
            AnchorPosition.CENTER);
    g.setSize(new SizeMetrics(
            0, SizeLayoutType.FILL,
            0, SizeLayoutType.FILL));

    LayoutManager l = getLayoutManager();
    l.remove(this.getDomainLabelWidget());
    l.remove(this.getRangeLabelWidget());
    l.remove(getLegendWidget());

    g.setRangeLabelWidth(0);
    g.setDomainLabelWidth(0);
    g.setPadding(0, 0, 0, 0);
    g.setMargins(0, 0, 0, 0);
    g.setGridPadding(0, 0, 0, 0);
    setPlotMargins(0, 0, 0, 0);
    setPlotPadding(0, 0, 0, 0);
