androidPlot黑色边框

Question

当我执行下面的代码并添加mySimpleXYPlot.getGraphWidget().getBorderPaint().setColor(Color.WHITE);时

当我在我的设备上启动应用程序时，它会崩溃。

我想要完成的是去掉整个图周围的黑色边框。它大约有2厘米厚，位于图表的顶部、左侧和底部。有什么办法可以去掉这个黑色边框吗？

public class MainActivity extends Activity {

private XYPlot mySimpleXYPlot;

@Override
public void onCreate(Bundle savedInstanceState)
{

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

 // Create a couple arrays of y-values to plot:
    Number[] days =   { 1  , 2   , 3   , 4   , 5   , 6   , 7 };
    Number[] values = { 380, 1433, 1965, 3200, 3651, 3215, 3217 };

    // initialize our XYPlot reference:
    mySimpleXYPlot = (XYPlot) findViewById(R.id.mySimpleXYPlot);
    mySimpleXYPlot.getBackgroundPaint().setColor(Color.WHITE);
    mySimpleXYPlot.setBorderStyle(XYPlot.BorderStyle.NONE, null, null);
    mySimpleXYPlot.getGraphWidget().getBackgroundPaint().setColor(Color.WHITE);
    mySimpleXYPlot.getGraphWidget().getGridBackgroundPaint().setColor(Color.WHITE);



    // Domain
    mySimpleXYPlot.getGraphWidget().setDomainLabelPaint(null);
    mySimpleXYPlot.getGraphWidget().setDomainOriginLinePaint(null);
    mySimpleXYPlot.setDomainStep(XYStepMode.INCREMENT_BY_VAL, days.length);     
    mySimpleXYPlot.setDomainValueFormat(new DecimalFormat("0"));


    //Range
    mySimpleXYPlot.getGraphWidget().setRangeOriginLinePaint(null);
    mySimpleXYPlot.setRangeStep(XYStepMode.SUBDIVIDE, values.length);
    mySimpleXYPlot.setRangeValueFormat(new DecimalFormat("0"));


    //Remove legend
    mySimpleXYPlot.getLayoutManager().remove(mySimpleXYPlot.getLegendWidget());
    mySimpleXYPlot.getLayoutManager().remove(mySimpleXYPlot.getDomainLabelWidget());
    mySimpleXYPlot.getLayoutManager().remove(mySimpleXYPlot.getRangeLabelWidget());
    mySimpleXYPlot.getLayoutManager().remove(mySimpleXYPlot.getTitleWidget());

    // Turn the above arrays into XYSeries':
    XYSeries series1 = new SimpleXYSeries(
            Arrays.asList(days),          
            Arrays.asList(values), 
            "Series1");                             // Set the display title of the series

    // Create a formatter to use for drawing a series using LineAndPointRenderer:
    LineAndPointFormatter series1Format = new LineAndPointFormatter(
            Color.rgb(0, 200, 0),                   // line color
            Color.rgb(0, 100, 0),                   // point color
            Color.CYAN);                            // fill color 

 // setup our line fill paint to be a slightly transparent gradient:
    Paint lineFill = new Paint();
    lineFill.setAlpha(200);
    lineFill.setShader(new LinearGradient(0, 0, 0, 250, Color.WHITE, Color.GREEN, Shader.TileMode.MIRROR));

    series1Format.setFillPaint(lineFill);

    // add a new series' to the xyplot:
    mySimpleXYPlot.addSeries(series1, series1Format);

    // by default, AndroidPlot displays developer guides to aid in laying out your plot.
    // To get rid of them call disableAllMarkup():
    mySimpleXYPlot.disableAllMarkup();
}

}

Answer 1

如果您想摆脱图形背后的所有颜色，您将需要以下三种方法。每一个都去掉了不同的部分。

//This gets rid of the gray grid
mySimpleXYPlot.getGraphWidget().getGridBackgroundPaint().setColor(Color.TRANSPARENT);

//This gets rid of the black border (up to the graph) there is no black border around the labels
mysimpleXYPlot.getBackgroundPaint().setColor(Color.TRANSPARENT);

//This gets rid of the black behind the graph
mySimpleXYPlot.getGraphWidget().getBackgroundPaint().setColor(Color.TRANSPARENT);

//With a new release of AndroidPlot you have to also set the border paint
plot.getBorderPaint().setColor(Color.TRANSPARENT);

希望这能有所帮助。

边框线可以通过此方法隐藏：

plot.setBorderPaint(null);
plot.setPlotMargins(0, 0, 0, 0);

Answer 3

我能够想出如何用这些信息来修复图表，但我必须将其中几个帖子的信息集中在一起。有4个不同的背景区域：*网格(和轴标签)*图形周围的区域*图形周围的边界。*边界周围的边际

网格的背景色和范围/域标签是使用plot.getGraphWidget().getBackgroundPaint().setColor(background_color);

• The区域设置的，网格周围的区域可以通过以下方式设置：plot.getBackgroundPaint().setColor(background_color);

• This

1. 在图形周围绘制的边框。你可以去掉边框：plot.setBorderPaint(null);

或设置背景颜色

plot.getBorderPaint().setColor(background_color);

1. 这会在整个绘图周围留下空白处。可以使用plot.setPlotMargins(0, 0, 0, 0);

将其删除

应该有一种方法来改变页边距的颜色，而不是简单地删除它，但没有费心弄清楚这一点。
