Question

我正在使用androidplot-core-0.6.1.jar，我正在修改quickstart教程中的SimpleXYPlotActivity示例。我已经删除了一些项目和边距/填充，但我想要做的并且无法找到方法如何删除图表左侧的空间。我在下面的图片中用红色标记了我要删除的空间。可以这样做吗？

How it looks

Red shows what I want to remove

活动代码：

public class MyXYPlotActivity extends Activity {

   private XYPlot plot;

   @Override
   public void onCreate(Bundle savedInstanceState)
   {
       super.onCreate(savedInstanceState);

       requestWindowFeature(Window.FEATURE_NO_TITLE);
       getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
       WindowManager.LayoutParams.FLAG_FULLSCREEN);

       setContentView(R.layout.simple_xy_plot_example);

       setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);

       plot = (XYPlot) findViewById(R.id.mySimpleXYPlot);

       Number[] series1Numbers = {1, 8, 5, 2, 7, 4};

       XYSeries series1 = new SimpleXYSeries(
               Arrays.asList(series1Numbers),          // SimpleXYSeries takes a List so turn our array into a List
               SimpleXYSeries.ArrayFormat.Y_VALS_ONLY, // Y_VALS_ONLY means use the element index as the x value
               "Foo");                               // Set the display title of the series

       LineAndPointFormatter series1Format = new LineAndPointFormatter();
       series1Format.setPointLabelFormatter(new PointLabelFormatter());
       series1Format.configure(getApplicationContext(),
               R.xml.line_point_formatter_with_plf1);

       plot.addSeries(series1, series1Format);

       plot.setDomainValueFormat(new DecimalFormat("#"));
       plot.setRangeValueFormat(new DecimalFormat("#"));

       plot.setTitle("Title");
       plot.setRangeBoundaries(0,10, BoundaryMode.FIXED);

       int length = 30;
       plot.setDomainBoundaries(1,length, BoundaryMode.FIXED);

       plot.setRangeStep(XYStepMode.INCREMENT_BY_VAL, 1);

       plot.setDomainStep(XYStepMode.INCREMENT_BY_VAL, 1);

       plot.setMarkupEnabled(true);

       plot.setTicksPerRangeLabel(1);
       plot.setTicksPerDomainLabel(1);
       plot.getGraphWidget().setDomainLabelOrientation(90);

       plot.getLayoutManager().remove(plot.getLegendWidget());
       plot.getLayoutManager().remove(plot.getRangeLabelWidget());
       plot.getLayoutManager().remove(plot.getDomainLabelWidget());

       plot.setPlotMargins(0, 0, 0, 0);
       plot.setPlotPadding(0, 0, 0, 0);

       plot.setBorderStyle(Plot.BorderStyle.SQUARE, null, null);

       plot.getRangeLabelWidget().setHeight(0);
       plot.getRangeLabelWidget().setWidth(0);
       plot.getRangeLabelWidget().setPadding(0, 0, 0, 0);
       plot.getRangeLabelWidget().setMargins(0, 0, 0, 0);

       plot.getDomainLabelWidget().setHeight(0);
       plot.getDomainLabelWidget().setWidth(0);
       plot.getDomainLabelWidget().setPadding(0, 0, 0, 0);
       plot.getDomainLabelWidget().setMargins(0, 0, 0, 0);

   }
}

编辑：我找到了解决方案：

XYGraphWidget g = plot.getGraphWidget();
g.setRangeLabelWidth(25);
g.setDomainLabelWidth(25);

以上内容有效。

看起来你想减少/删除graphWidget的边距和/或填充。尝试将这些添加到您的代码中以查看它是否具有所需的效果......您显然需要使用适合您的应用程序的非零值：

plot.getGraphWidget().setMarginLeft(0);
plot.getGraphWidget().setPaddingLeft(0);
