android 图表引擎AChartEngine(柱状图)

使用AChartEngine画动态柱状图：

1.定义类：

import java.util.List;

import org.achartengine.ChartFactory;
import org.achartengine.GraphicalView;
import org.achartengine.chart.BarChart.Type;
import org.achartengine.model.XYMultipleSeriesDataset;
import org.achartengine.renderer.XYMultipleSeriesRenderer;

import android.content.Context;
import android.graphics.Color;
import android.graphics.Paint.Align;

public class DynamicBarChart {

 2.使用方法：

 

private void addDynamicBarchart(Context context) {
		mDynamicBarChartLayout = (LinearLayout) findViewById(R.id.dynamicbarchart);

		mDynamicBarChart = new DynamicBarChart(context);
		chartView = mDynamicBarChart.getChartView();
		chartView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
				LinearLayout.LayoutParams.MATCH_PARENT));
		chartView.setBackgroundColor(Color.BLACK);
		mDynamicBarChartLayout.addView(chartView);

	}

 

private void updateChart() {
		updateVaules(); //更新Values
		mDynamicBarChart.setValues(values);
		mDynamicBarChart.setView();

		mDynamicBarChartLayout.removeAllViews();

		chartView = mDynamicBarChart.getChartView();
		chartView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
				LinearLayout.LayoutParams.MATCH_PARENT));
		chartView.setBackgroundColor(Color.BLACK);
		mDynamicBarChartLayout.addView(chartView);

	}
