I am working on Pie charts using AChartEngine library. Here I want to disable chart values to show on charts, but only those whose content value is 0.

Now I am using it like:

         public Intent execute_assetLifecycle(Context context,RelativeLayout parent) {
    int[] colors = new int[] { Color.RED, Color.DKGRAY, Color.BLUE, Color.CYAN,Color.GREEN,Color.GRAY };
    DefaultRenderer renderer = buildCategoryRenderer(colors);

    CategorySeries categorySeries = new CategorySeries("Title1");


        categorySeries.add("30 Days=" days_count_30);  

        categorySeries.add("60 Days=", days_count_60);

        categorySeries.add("90 Days=", days_count_90);

        categorySeries.add("180 Days=", days_count_180);


    mChartView2=ChartFactory.getPieChartView(context, categorySeries,renderer);

    parent.addView(mChartView2);
    return ChartFactory.getPieChartIntent(context, categorySeries, renderer,null);
    }

    protected DefaultRenderer buildCategoryRenderer(int[] colors) {
    DefaultRenderer renderer = new DefaultRenderer();
    for (int color : colors) {
    SimpleSeriesRenderer r = new SimpleSeriesRenderer();
    r.setColor(color);
    renderer.addSeriesRenderer(r);

    }
    return renderer;
    }

I am using the above code to display pie chart with display values, but I want to show only those display values which are >0 otherwise They will not be shown on the charts as label like: 30 days=0

Please suggest any method that would stop displaying chart values when its value ==0

在添加系列之前，我会使用 If 语句检查值是否为零。也许为类似的东西制作自己的包装函数categorySeries.add：

private void add(String category,double value){
    if(value != 0){
        categorySeries.add(category,value);
    }
}

您可能必须将渲染数量限制为实际添加的系列数量。
