我正在使用Achartengine制作动态折线图，这是在处理静态数据但不处理动态数据。实际，计划和月份是动态的。我想根据实际，计划和月份的值创建折线图。我正在使用下面的代码。
private void drawChart() {
XYSeries actualSeries = new XYSeries("Actual");
// Creating an XYSeries for Expense<br />
XYSeries planSeries = new XYSeries("Plan");
// Adding data to Income and Expense Series
for (int i = 0; i <actualList.size; i++) {
actualSeries.add(i,Double.parseDouble(actualList.get(i)));
planSeries.add(i,Double.parseDouble(planList.get(i)));
}
// Creating a dataset to hold each series
XYMultipleSeriesDataset xyMultipleSeriesDataset = new XYMultipleSeriesDataset();
// Adding Income Series to the dataset
xyMultipleSeriesDataset.addSeries(actualSeries);
// Adding Expense Series to dataset
xyMultipleSeriesDataset.addSeries(planSeries);
XYSeriesRenderer actualRenderer = new XYSeriesRenderer();
actualRenderer.setColor(Color.GREEN);
actualRenderer.setPointStyle(PointStyle.CIRCLE);
actualRenderer.setFillPoints(true);
actualRenderer.setLineWidth(2);
actualRenderer.setDisplayChartValues(true);
// Creating XYSeriesRenderer to customize expenseSeries
XYSeriesRenderer planRenderer = new XYSeriesRenderer();
planRenderer.setColor(Color.RED);
planRenderer.setPointStyle(PointStyle.CIRCLE);
planRenderer.setFillPoints(true);
planRenderer.setLineWidth(2);
planRenderer.setDisplayChartValues(true);
XYMultipleSeriesRenderer multiRenderer = new XYMultipleSeriesRenderer();
multiRenderer.setApplyBackgroundColor(true);
multiRenderer.setBackgroundColor(Color.WHITE);
multiRenderer.setMarginsColor(Color.WHITE);
multiRenderer.setLabelsColor(Color.RED);
multiRenderer.setPanEnabled(false, false);
/* multiRenderer.setYLabels(5);
multiRenderer.setXLabels(1);
*/ multiRenderer.setXLabelsColor(Color.BLACK);
multiRenderer.setYLabelsColor(0, Color.BLACK);
//* multiRenderer.setShowGridX(true);
//multiRenderer.setShowGridY(true)
multiRenderer.setGridColor(Color.BLACK);
multiRenderer.setChartTitle("Plan vs Actual Curve");
multiRenderer.setXTitle("Months");
multiRenderer.setYTitle("plan/actual");
multiRenderer.setZoomButtonsVisible(false);
for (int i = 0; i < monthList.size(); i++) {
multiRenderer.addXTextLabel(i + 1, monthList.get(i).toString());
}
multiRenderer.addSeriesRenderer(actualRenderer);
multiRenderer.addSeriesRenderer(planRenderer);
// Getting a reference to LinearLayout of the MainActivity Layout<br />
LinearLayout chartContainer = (LinearLayout) mView.findViewById(R.id.chart_container);
// Creating a Line Chart<br />
GraphicalView chart = ChartFactory.getLineChartView(getActivity(), xyMultipleSeriesDataset, multiRenderer);
chartContainer.addView(chart);
if (chart != null) {
chartContainer.removeView(chart);
chart.repaint();
}
}
Thanks in advance
