Android图表库MPAndroidChart(十二)——来点不一样的，正负堆叠条形图

接上篇，今天要说的，和上篇的类似，只是方向是有相反的两面，我们先看下效果

实际上这样就导致了我们的代码是比较类似的，先来看下我们的基本实现

一.基本实现

布局还是那个布局，只不过是横向的了

而初始化这些也都是大同小异

//正负堆叠条形图        mHorizontalBarChart = (HorizontalBarChart) findViewById(R.id.mHorizontalBarChart);        mHorizontalBarChart.setOnChartValueSelectedListener(this);        mHorizontalBarChart.setDrawGridBackground(false);        mHorizontalBarChart.getDescription().setEnabled(false);        // 扩展现在只能分别在x轴和y轴        mHorizontalBarChart.setPinchZoom(false);        mHorizontalBarChart.setDrawBarShadow(false);        mHorizontalBarChart.setDrawValueAboveBar(true);        mHorizontalBarChart.setHighlightFullBarEnabled(false);        mHorizontalBarChart.getAxisLeft().setEnabled(false);        mHorizontalBarChart.getAxisRight().setAxisMaximum(25f);        mHorizontalBarChart.getAxisRight().setAxisMinimum(-25f);        mHorizontalBarChart.getAxisRight().setDrawGridLines(false);        mHorizontalBarChart.getAxisRight().setDrawZeroLine(true);        mHorizontalBarChart.getAxisRight().setLabelCount(7, false);        mHorizontalBarChart.getAxisRight().setValueFormatter(new CustomFormatter());        mHorizontalBarChart.getAxisRight().setTextSize(9f);        XAxis xAxis = mHorizontalBarChart.getXAxis();        xAxis.setPosition(XAxis.XAxisPosition.BOTH_SIDED);        xAxis.setDrawGridLines(false);        xAxis.setDrawAxisLine(false);        xAxis.setTextSize(9f);        xAxis.setAxisMinimum(0f);        xAxis.setAxisMaximum(110f);        xAxis.setCenterAxisLabels(true);        xAxis.setLabelCount(12);        xAxis.setGranularity(10f);        //日期格式化        xAxis.setValueFormatter(new IAxisValueFormatter() {            private DecimalFormat format = new DecimalFormat("###");            @Override            public String getFormattedValue(float value, AxisBase axis) {                return format.format(value) + "-" + format.format(value + 10);            }            @Override            public int getDecimalDigits() {                return 0;            }        });        Legend l = mHorizontalBarChart.getLegend();        l.setVerticalAlignment(Legend.LegendVerticalAlignment.BOTTOM);        l.setHorizontalAlignment(Legend.LegendHorizontalAlignment.RIGHT);        l.setOrientation(Legend.LegendOrientation.HORIZONTAL);        l.setDrawInside(false);        l.setFormSize(8f);        l.setFormToTextSpace(4f);        l.setXEntrySpace(6f);        // 重要:当使用负值在堆叠酒吧,总是确保-值数组中的第一个        ArrayList
     
       yValues = new ArrayList
      
       ();        yValues.add(new BarEntry(5, new float[]{-10, 10}));        yValues.add(new BarEntry(15, new float[]{-12, 13}));        yValues.add(new BarEntry(25, new float[]{-15, 15}));        yValues.add(new BarEntry(35, new float[]{-17, 17}));        yValues.add(new BarEntry(45, new float[]{-19, 20}));        yValues.add(new BarEntry(55, new float[]{-19, 19}));        yValues.add(new BarEntry(65, new float[]{-16, 16}));        yValues.add(new BarEntry(75, new float[]{-13, 14}));        yValues.add(new BarEntry(85, new float[]{-10, 11}));        yValues.add(new BarEntry(95, new float[]{-5, 6}));        yValues.add(new BarEntry(105, new float[]{-1, 2}));        BarDataSet set = new BarDataSet(yValues, "全国人口普查");        set.setValueFormatter(new CustomFormatter());        set.setValueTextSize(7f);        set.setAxisDependency(YAxis.AxisDependency.RIGHT);        set.setColors(new int[]{Color.rgb(99, 67, 72), Color.rgb(14, 181, 136)});        set.setStackLabels(new String[]{
    "男人", "女人"});        String[] xLabels = new String[]{
    "0-10", "10-20", "20-30", "30-40", "40-50", "50-60", "60-70", "70-80", "80-90", "90-100", "100+"};        BarData data = new BarData(set);        data.setBarWidth(8.5f);        mHorizontalBarChart.setData(data);        mHorizontalBarChart.invalidate();
      
     

这里我并没有写setData的方法，直接就模拟了一些数据，可以看出，这个图标是异常的简单，当我们运行之后就可以知道，这个实现的效果和上图的效果是一致的

二.显示顶点值

三.x轴动画

四.y轴动画

五.xy轴动画

六.显示边框

现在我把源码贴上

activity_statkedbar_negative.xml

实际上比较类似，可以看下代码

StackedBarActivityNegative

public class StackedBarActivityNegative extends BaseActivity implements OnChartValueSelectedListener,View.OnClickListener {
         private HorizontalBarChart mHorizontalBarChart;    //显示顶点值    private Button btn_show_values;    //x轴动画    private Button btn_anim_x;    //y轴动画    private Button btn_anim_y;    //xy轴动画    private Button btn_anim_xy;    //保存到sd卡    private Button btn_save_pic;    //切换自动最大最小值    private Button btn_auto_mix_max;    //高亮显示    private Button btn_actionToggleHighlight;    //显示边框    private Button btn_show_border;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_statkedbar_negative);        initView();    }    //初始化View    private void initView() {        //基本控件        btn_show_values = (Button) findViewById(R.id.btn_show_values);        btn_show_values.setOnClickListener(this);        btn_anim_x = (Button) findViewById(R.id.btn_anim_x);        btn_anim_x.setOnClickListener(this);        btn_anim_y = (Button) findViewById(R.id.btn_anim_y);        btn_anim_y.setOnClickListener(this);        btn_anim_xy = (Button) findViewById(R.id.btn_anim_xy);        btn_anim_xy.setOnClickListener(this);        btn_save_pic = (Button) findViewById(R.id.btn_save_pic);        btn_save_pic.setOnClickListener(this);        btn_auto_mix_max = (Button) findViewById(R.id.btn_auto_mix_max);        btn_auto_mix_max.setOnClickListener(this);        btn_actionToggleHighlight = (Button) findViewById(R.id.btn_actionToggleHighlight);        btn_actionToggleHighlight.setOnClickListener(this);        btn_show_border = (Button) findViewById(R.id.btn_show_border);        btn_show_border.setOnClickListener(this);        //正负堆叠条形图        mHorizontalBarChart = (HorizontalBarChart) findViewById(R.id.mHorizontalBarChart);        mHorizontalBarChart.setOnChartValueSelectedListener(this);        mHorizontalBarChart.setDrawGridBackground(false);        mHorizontalBarChart.getDescription().setEnabled(false);        // 扩展现在只能分别在x轴和y轴        mHorizontalBarChart.setPinchZoom(false);        mHorizontalBarChart.setDrawBarShadow(false);        mHorizontalBarChart.setDrawValueAboveBar(true);        mHorizontalBarChart.setHighlightFullBarEnabled(false);        mHorizontalBarChart.getAxisLeft().setEnabled(false);        mHorizontalBarChart.getAxisRight().setAxisMaximum(25f);        mHorizontalBarChart.getAxisRight().setAxisMinimum(-25f);        mHorizontalBarChart.getAxisRight().setDrawGridLines(false);        mHorizontalBarChart.getAxisRight().setDrawZeroLine(true);        mHorizontalBarChart.getAxisRight().setLabelCount(7, false);        mHorizontalBarChart.getAxisRight().setValueFormatter(new CustomFormatter());        mHorizontalBarChart.getAxisRight().setTextSize(9f);        XAxis xAxis = mHorizontalBarChart.getXAxis();        xAxis.setPosition(XAxis.XAxisPosition.BOTH_SIDED);        xAxis.setDrawGridLines(false);        xAxis.setDrawAxisLine(false);        xAxis.setTextSize(9f);        xAxis.setAxisMinimum(0f);        xAxis.setAxisMaximum(110f);        xAxis.setCenterAxisLabels(true);        xAxis.setLabelCount(12);        xAxis.setGranularity(10f);        //日期格式化        xAxis.setValueFormatter(new IAxisValueFormatter() {            private DecimalFormat format = new DecimalFormat("###");            @Override            public String getFormattedValue(float value, AxisBase axis) {                return format.format(value) + "-" + format.format(value + 10);            }            @Override            public int getDecimalDigits() {                return 0;            }        });        Legend l = mHorizontalBarChart.getLegend();        l.setVerticalAlignment(Legend.LegendVerticalAlignment.BOTTOM);        l.setHorizontalAlignment(Legend.LegendHorizontalAlignment.RIGHT);        l.setOrientation(Legend.LegendOrientation.HORIZONTAL);        l.setDrawInside(false);        l.setFormSize(8f);        l.setFormToTextSpace(4f);        l.setXEntrySpace(6f);        // 重要:当使用负值在堆叠酒吧,总是确保-值数组中的第一个        ArrayList

好了，这个图表就是这么简单，到这里就结束了
