title: Menu and a ContextMenu for a aChartengine chart
body: <p>Is it possible? have anyone been doing this before? I don't know where to start.</p>
  
  <p>I mostly need the menu, not the context menu.</p>
  
  <p>My "BudgetPieChart" class</p>
  
  <pre><code>public class ExpensesByCategoriesPieChart extends AbstractChart{
  
      private DataToArray dta;
  
      @Override
      public String getName() {
          return MyApplication.getContext().getString(R.string.ExpensesByCategoriesPieChartName);
      }
  
      @Override
      public String getDesc() {
          return "The budget per project for this year (pie chart)";      
      }
  
      @Override
      public Intent execute(Context context) {
  
          dta = new DataToArray();
          String[] categories = dta.expenseByCategoriesToArray();
          double[] values = dta.expensesValuesByCategoriesToArray();      
          int[] colors = dta.getColorsArray(categories.length);
  
          DefaultRenderer renderer = buildCategoryRenderer(colors);
          renderer.setZoomButtonsVisible(true);
          renderer.setZoomEnabled(true);
          renderer.setChartTitleTextSize(20);
          return ChartFactory.getPieChartIntent(context, buildCategoryDataset("Wydatki kategoriami", categories, values), renderer, "Wydatki");
      }
  
      public CustomGraphicalView createView(
              CustomGraphicalView customGraphicalView) {
          // what do I do here?
          return null;
      }
  }
  </code></pre>
