我是
Android新手,我正在尝试使用AChartEngine创建一个条形图,它有3个条形图,每个条形图应该是不同的颜色.我尝试使用多个系列但不能使我的x轴值与条形对齐
protected void onResume() {
super.onResume();
layout = (LinearLayout) findViewById(R.id.chart);
if (mChartView == null)
{
PeakSeries = new XYSeries("Income");
ForecastPeakSeries = new XYSeries("Expense");
ForecastSeries = new XYSeries("Expense");
int[] x = { 1,2,3};
int income = 2000;
int expense = 2700;
System.out.println("Here");
Series1.add(x[0],income);
Series2.add(x[1],expense);
Series3.add(x[2],expense);
// Creating a dataset to hold each series
XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
dataset.addSeries(Series1);
dataset.addSeries(Series2);
dataset.addSeries(Series3);
XYSeriesRenderer Renderer1 = new XYSeriesRenderer();
Renderer1 .setColor(Color.RED);
Renderer1 .setChartValuesTextSize(18);
Renderer1 .setFillPoints(true);
Renderer1 .setDisplayChartValues(true);
// Creating XYSeriesRenderer to customize expenseSeries
XYSeriesRenderer Renderer2 = new XYSeriesRenderer();
Renderer2 .setColor(Color.YELLOW);
Renderer2 .setChartValuesTextSize(18);
Renderer2 .setDisplayChartValues(true);
XYSeriesRenderer Renderer3 = new XYSeriesRenderer();
Renderer3 .setColor(Color.CYAN);
Renderer3 .setChartValuesTextSize(18);
Renderer3 .setFillPoints(true);
Renderer3 .setChartValuesTextAlign(Align.CENTER);
Renderer3 .setDisplayChartValues(true);
// Creating a XYMultipleSeriesRenderer to customize the whole chart
double[] range = {0,5,5};
multiRenderer.setMargins(new int[] {50,50,50});
multiRenderer.setAxisTitleTextSize(16);
multiRenderer.setChartTitleTextSize(30);
multiRenderer.setLabelsTextSize(15);
multiRenderer.setLegendTextSize(20);
multiRenderer.setLegendHeight(40);
multiRenderer.setBarSpacing(-0.7);
multiRenderer.setAxesColor(Color.WHITE);
multiRenderer.setInitialRange(range,1);
multiRenderer.setXAxisMin(0.4);
multiRenderer.setXAxisMax(4);
multiRenderer.setYAxisMax(5000);
multiRenderer.setYAxisMin(0);
multiRenderer.setXLabelsAlign(Align.RIGHT);
multiRenderer.setYLabelsAlign(Align.RIGHT);
//multiRenderer.s(Align.LEFT);
multiRenderer.setPanEnabled(false,false);
multiRenderer.setZoomEnabled(true,true);
multiRenderer.setChartTitle("7 Day Outlook - Maxiumum Demand");
multiRenderer.setXTitle("Date");
multiRenderer.setYTitle("MW");
multiRenderer.addSeriesRenderer(Renderer1 );
multiRenderer.addSeriesRenderer(Renderer2 );
multiRenderer.addSeriesRenderer(Renderer3 );
final GraphicalView mChartView = ChartFactory.getBarChartView(TestSevenDay1.this,dataset,multiRenderer,Type.DEFAULT);
layout.addView(mChartView);
}
else
{
mChartView.repaint();
}
}
任何帮助是极大的赞赏.
解决方法
我通过在GetBarChartView中将Type从Type.Default设置为Type.Stacked来处理它.
ChartFactory.getBarChartView(TestSevenDay1.this,Type.STACKED);
