怎么把hellochart做的柱形图换成立体的柱子

[qq_38065030]

柱状图代码如下：

package com.example.a12438.mytubiao;

import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;

import java.util.ArrayList;
import java.util.List;

import lecho.lib.hellocharts.gesture.ZoomType;
import lecho.lib.hellocharts.listener.ColumnChartOnValueSelectListener;
import lecho.lib.hellocharts.model.Axis;
import lecho.lib.hellocharts.model.AxisValue;
import lecho.lib.hellocharts.model.Column;
import lecho.lib.hellocharts.model.ColumnChartData;
import lecho.lib.hellocharts.model.SubcolumnValue;
import lecho.lib.hellocharts.util.ChartUtils;
import lecho.lib.hellocharts.view.ColumnChartView;

public class Zhuzhuangtu extends AppCompatActivity {
    //声明所需变量
    public final static String[] months = new String[] { "Jan", "Feb", "Mar",
            "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec", };
    private Button fanhui2;
    ColumnChartView columnChart;
    ColumnChartData columnData;
    List<Column> lsColumn = new ArrayList<Column>();
    List<SubcolumnValue> lsValue;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.zhuzhuang);
        columnChart=findViewById(R.id.columnChart);
        fanhui2=findViewById(R.id.fanhui2);
        dataInit();
        fanhui2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent=new Intent(Zhuzhuangtu.this, MainActivity.class);
                startActivity(intent);
            }
        });
    }


    //初始化数据并显示在图表上
    private void dataInit() {
        int numSubcolumns = 1;
        int numColumns = months.length;
        List<AxisValue> axisValues = new ArrayList<AxisValue>();
        List<Column> columns = new ArrayList<Column>();
        List<SubcolumnValue> values;
        for (int i = 0; i < numColumns; ++i) {
            values = new ArrayList<SubcolumnValue>();
            for (int j = 0; j < numSubcolumns; ++j) {
                values.add(new SubcolumnValue((float) Math.random() * 50f + 5,
                        ChartUtils.pickColor()));
            }
            // 点击柱状图就展示数据量
            axisValues.add(new AxisValue(i).setLabel(months[i]));
            columns.add(new Column(values).setHasLabelsOnlyForSelected(true));
        }
        columnData = new ColumnChartData(columns);
        columnData.setAxisXBottom(new Axis(axisValues).setHasLines(true)
                .setTextColor(Color.BLACK));
        columnData.setAxisYLeft(new Axis().setHasLines(true)
                .setTextColor(Color.BLACK).setMaxLabelChars(2));
        columnChart.setColumnChartData(columnData);

        // Set value touch listener that will trigger changes for chartTop.
        columnChart.setOnValueTouchListener((ColumnChartOnValueSelectListener) new ValueTouchListener());
        // Set selection mode to keep selected month column highlighted.
        columnChart.setValueSelectionEnabled(true);
        columnChart.setZoomType(ZoomType.HORIZONTAL);
    }

    /**

    private class ValueTouchListener implements
            ColumnChartOnValueSelectListener {
        @Override
        public void onValueSelected(int columnIndex, int subcolumnIndex,
                                    SubcolumnValue value) {
            // generateLineData(value.getColor(), 100);
        }
        @Override
        public void onValueDeselected() {
            // generateLineData(ChartUtils.COLOR_GREEN, 0);
        }
    }
}
layout布局：
