当我执行下面的代码并添加mySimpleXYPlot.getGraphWidget().getBorderPaint().setColor(Color.WHITE);
当我在我的设备上启动它时,应用程序崩溃了。
我想要完成的是摆脱整个图形周围的黑色边框。它位于图表的顶部,左侧和底部两侧约2厘米厚。有什么办法可以摆脱这个黑色边框吗?
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();
}
}

如果您想要摆脱图表背后的所有颜色,则需要以下三种方法。每个都摆脱了不同的部分。
//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);
希望这有帮助。

此方法可以隐藏边框线:
plot.setBorderPaint(null);
plot.setPlotMargins(0, 0, 0, 0);
答案 2 :(得分:0)
我能够弄清楚如何使用这些信息修复图表,但我不得不将这些帖子中的一些信息汇总起来。似乎有4个不同的背景区域: *网格(和轴标签) *图表周围的区域 *图表边框。 *边界边缘
使用设置网格和范围/域标签的背景颜色
plot.getGraphWidget().getBackgroundPaint().setColor(background_color);
网格周围的区域可以通过以下方式设置:
plot.getBackgroundPaint().setColor(background_color);
这仍然会在图表周围留下一个边框。你可以摆脱边界:
plot.setBorderPaint(null);
或设置背景颜色
plot.getBorderPaint().setColor(background_color);
plot.setPlotMargins(0, 0, 0, 0);
应该有一种方法可以改变边距的颜色,而不是仅仅删除它,但是没有办法解决这个问题。
