Question

无论如何使用MPAndroidChart动态设置值为Yaxis。我搜索了问题，但在这里我没有得到任何答案。我必须将运行时值设置为Yaxis。我也试过setGranularity（），但是这个方法显示的错误像can't resolve method setGranularity(float)。请帮助我。

你可以这样尝试

 private ArrayList<Entry> setYAxisValues(){
    ArrayList<Entry> yVals = new ArrayList<Entry>();

    //Change to your values 

    yVals.add(new Entry(0, 6));
    yVals.add(new Entry(1, 4));
    yVals.add(new Entry(2, 5));
    yVals.add(new Entry(3, 4));
    yVals.add(new Entry(4, 3));
    yVals.add(new Entry(5, 2));
    yVals.add(new Entry(6, 3));
    yVals.add(new Entry(7, 4));
    yVals.add(new Entry(8, 5));
    yVals.add(new Entry(9, 3));
    yVals.add(new Entry(10, 2));
    yVals.add(new Entry(11,4));




    return yVals;
}

private void setData() {

    //call this method to set data
    ArrayList<Entry> yVals = setYAxisValues();

    LineDataSet set1;

    // create a dataset and give it a type
    set1 = new LineDataSet(yVals, "DataSet 1");

    set1.setFillAlpha(110);
    set1.setColor(Color.WHITE);
    set1.setCircleColor(Color.WHITE);
    set1.setLineWidth(1f);
    set1.setCircleRadius(3f);
    set1.setDrawCircleHole(false);
    set1.setValueTextSize(9f);

    ArrayList<ILineDataSet> dataSets = new ArrayList<ILineDataSet>();
    dataSets.add(set1); // add the datasets

    // create a data object with the datasets
    LineData data = new LineData(dataSets);

    // set data to LineChart
    mChart.setData(data);
    mChart.setVisibleXRangeMaximum(4); // allow 20 values to be displayed at once on the x-axis, not more
    mChart.moveViewToX(10);
}
