在 Android 中绘制图形

Question

我想在 Android 中绘制一个图表，这样在 X 轴上我想要一月、二月、三月、四月、五月、六月、八月、九月、十月、十一月、十二月等月份，在 Y 轴上你想要多少该特定月份的支出。

我有一个在 android 上绘制图形的代码：-

mySimpleXYPlot = (XYPlot) findViewById(R.id.mySimpleXYPlot);
        Number[] series1Numbers = { 1, 8, 5, 2, 7, 4 };
        Number[] series2Numbers = { 4, 6, 3, 8, 2, 10 };
        XYSeries series1 = new SimpleXYSeries(Arrays.asList(series1Numbers),
        SimpleXYSeries.ArrayFormat.Y_VALS_ONLY,"Series1");
        XYSeries series2 = new SimpleXYSeries(Arrays.asList(series2Numbers),
        SimpleXYSeries.ArrayFormat.Y_VALS_ONLY, "Series2");

        LineAndPointFormatter series1Format = new LineAndPointFormatter(
                Color.rgb(0, 200, 0), // line color
                Color.rgb(0, 100, 0), // point color
                Color.rgb(150, 190, 150)); // fill color (optional)
                mySimpleXYPlot.addSeries(series1, series1Format);
                mySimpleXYPlot.addSeries(
                series2,
                new LineAndPointFormatter(Color.rgb(0, 0, 200),
                Color.rgb(0, 0, 100), Color.rgb(150, 150, 190)));
                mySimpleXYPlot.setTicksPerRangeLabel(3);
                }

但我想在 X 轴上显示月份和在 Y 轴上他们在该月花费的特定金额。这些值来自数据库，他们花钱的月份，形式为 mon 他们花费的 reuqired 月份，Name 包含他们在该月花费的值。

try {
        myDB = this.openOrCreateDatabase("Expense_db", MODE_PRIVATE, null);

        Cursor c = myDB.rawQuery("SELECT project_android.Month AS Month_Real, " +
                  "SUM(Total) AS OrderTotal FROM project_android " +
                  "WHERE Year='"+value1+"' " +
                  "GROUP BY project_android.Month " , null);

                     int Column1 = c.getColumnIndex("Month_Real");
                     int Column2 = c.getColumnIndex("OrderTotal");
                     //int current=0;
                  // Check if our result was valid.
                     c.moveToFirst();
                     if (c != null) {
                      // Loop through all Results
                     do {
                       mon = c.getString(Column1);               
                       Name = c.getDouble(Column2);
                       Log.i(TAG, "Testing_value_graph_month: " + Name + " | " + mon + " " );

                     }while(c.moveToNext());
                     c.close();
                     }
                     }
    catch(Exception e) {
        Log.e("Error", "Error", e);
       } finally {
        if (myDB != null)
         myDB.close();
       }

任何帮助将不胜感激..！
