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.有什么方法可以摆脱这个黑色的边界？
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,// 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(0,250,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();
}
}
解决方法
如果要删除图表背后的所有颜色,则需要以下三种方法.每个都摆脱不同的部分.
//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);
希望这可以帮助.
