Question

我正在使用achartengine渲染饼图，渲染的图表与图表一起在大屏幕设备上显示一条线。（如5.5公司）。该线条位于红色矩形中。（我绘制矩形以指出不需要的线）

<?xml version="1.0" encoding="utf-8"?>

Java Code Section：

 private void initData(RelativeLayout chartLayout, double uncompleted, double completed) {
        if (uncompleted == 0) {
            completed = 1;
        }
        double[] values = {uncompleted,completed };
        String[] colors = {//uncompleted, completed
                "#82CA9C", "#F5F0ED"
        };
        CategorySeries series = new CategorySeries("");
        int length = values.length;

        for (int i = 0; i < length; i++) {
            series.add(values[i]);
        }

        DefaultRenderer renderer = new DefaultRenderer();
        for (int i = 0; i < length; i++) {
            SimpleSeriesRenderer seriesRenderer = new SimpleSeriesRenderer();
            seriesRenderer.setColor(Color.parseColor(colors[i]));

            renderer.addSeriesRenderer(seriesRenderer);
        }
        //  renderer.setAxesColor(Color.TRANSPARENT);
        // renderer.setBackgroundColor(Color.parseColor("#82CA9C"));
        renderer.setLabelsColor(Color.TRANSPARENT);
        drawChart(series, renderer, chartLayout);
    }

    private void drawChart(CategorySeries series,
                           DefaultRenderer renderer, RelativeLayout chartLayout) {

        GraphicalView mGraphView = null;


            mGraphView =
                    ChartFactory.getPieChartView(context, series, renderer);
            chartLayout.addView(mGraphView);

    }

尝试在代码中添加renderer.setShowLabels(false);和renderer.setShowLegend(false);。这将隐藏图例和标签。您在代码中使颜色透明的标签，而不是完全隐藏它们。
