我使用Chart Engine成功显示图表,但我遇到了以下问题:
请任何人都可以帮助我。谢谢。
以下是我的代码:
public class MainActivity extends Activity {
private String[] mMonth = new String[] {
"Jan", "Feb" , "Mar", "Apr", "May", "Jun",
"Jul", "Aug" , "Sep", "Oct", "Nov", "Dec"
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
openChart();
}
private void openChart(){
double[] distribution = { 10,200,3,400,500,60} ;
String[] dis = { "10","200","13","400","500","60"} ;
// Color of each Pie Chart Sections
int[] colors = { Color.BLUE, Color.MAGENTA, Color.GREEN, Color.CYAN, Color.RED,
Color.YELLOW };
// Instantiating CategorySeries to plot Pie Chart
CategorySeries distributionSeries = new CategorySeries("Sample");
for(int i=0 ;i < distribution.length;i++){
// Adding a slice with its values and name to the Pie Chart
distributionSeries.add(dis[i],distribution[i]);
}
// Instantiating a renderer for the Pie Chart
DefaultRenderer defaultRenderer = new DefaultRenderer();
for(int i = 0 ;i<distribution.length;i++){
SimpleSeriesRenderer seriesRenderer = new SimpleSeriesRenderer();
seriesRenderer.setColor(colors[i]);
seriesRenderer.setDisplayChartValues(true);
// Adding a renderer for a slice
defaultRenderer.setShowLegend(false);
defaultRenderer.addSeriesRenderer(seriesRenderer);
int mar[]=defaultRenderer.getMargins();
System.out.println(mar);
}
// Creating an intent to plot bar chart using dataset and multipleRenderer
Intent intent = ChartFactory.getPieChartIntent(getBaseContext(), distributionSeries , defaultRenderer, "");
// Start Activity
startActivity(intent);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
答案 0 :(得分:0)
您可以使用以下方式设置边距:
defaultRenderer.setMargins(margins);
您可以通过以下方式禁用平移:
defaultRenderer.setPanEnabled(false, false);
您可以在视图中创建图表并将其嵌入到为其定义布局的活动中,请参阅this。
