我用阿卡通做了普通的折线图,可以平移、缩放等。
最初,这张图表在平底锅上消失了。
我得到的opengl渲染警告-路径太大,无法渲染成纹理。
我把硬件加速变成了错误,这就解决了问题。
现在,当我缩放图表,如果数据点超出可见区域,图形消失,它将轴设置为10000到0万。
请参考随附的截图。
当点位于可见区域时:
当我缩放时,这些点超出了可见区域:
这是图书馆的问题吗?
如果有的话,有人能解决这个问题吗?

下面是一些代码:

        leftDate = (TextView) findViewById(R.id.left_date);
        rightDate = (TextView) findViewById(R.id.right_date);

        layout.setEnabled(true);
        mChartView = ChartFactory.getLineChartView(this, mDataset,

                    .getObject(Controller.getAppBackgroundContext());
            if (fetchWeight.getData().size() != 0) {

                        System.out.println("default start date = "
                                + default_start_date);
                        mCurrentSeries.add(default_start_date, kilo);

        mY.setText("");
        // repaint the chart such as the newly added point to be visible
        mChartView.repaint();

下面是泛听众:
            mChartView.addPanListener(new PanListener() {

            private double timestampdouble;
            private Integer image_index;
            private int mid_value;
            private Double max_double;
            private Double min_double;

            public void panApplied() {
                // customListAdapter.setGraphTouched(true);

                ArrayList<Long> insideweights = new ArrayList<Long>();
                double minx = mRenderer.getXAxisMin();
                double maxx = mRenderer.getXAxisMax();
                long minx_default = (long) minx;
                long maxx_default = (long) maxx;
                // change UI onscrollview minx & maxx
                leftDate.setText("" + getDateFormat(minx_default));
                rightDate.setText("" + getDateFormat(maxx_default));
                new AsyncScroll(minx_default, maxx_default).execute();
                double getmax_weight = get_max_weight();
                double getmin_weight = get_min_weight();
                if (minx_default <= default_start_date) {
                    mRenderer.setRange(new double[] { default_start_date,
                            maxx, getmin_weight - 20, getmax_weight + 20 });

                } else {
                    mRenderer.setRange(new double[] { minx, maxx,
                            getmin_weight - 20, getmax_weight + 20 });
                }



            }

GETXMax权重/GETA MIN权重从Y轴得到最小值和最大点,我用它们来渲染图。
这是一个混乱的代码,但我不能在这里张贴整个代码。

最佳答案

setFillBelowLinesetFillBelowLineColor已弃用。
尝试

FillOutsideLine fill = new FillOutsideLine(FillOutsideLine.Type.BOUNDS_ABOVE);
    fill.setColor(Color.GREEN);
    renderer.addFillOutsideLine(fill );
