ChartView

ChartView是一个Android开源图表库。目前仅支持折线图，曲线图，柱状图，饼状图，以及折线图和曲线图点击之后的状态变化，可以选择是画一个图片还是一个背景框。

Screens

折线图和曲线图:

饼状图有内圆:

饼状图没有内圆:

Usage

Gradle

• Step 1. Add LineChartView

    dependencies {
           compile 'com.veken:chart_view:1.0.2'
    }

折线图

XML

  <com.veken.linecharviewmodule.LineChartView
            android:id="@+id/chart_view"
            android:layout_width="match_parent"
            android:layout_height="300dp"
            app:showPicResource="@mipmap/ic_launcher"
            app:defaultStrokeWidth="0.5dp"
            app:pointClickRadius="3dp"
            app:defaultTextSize="16sp"
            app:pointDefaultRadius="2dp"
            app:isNeedBg="true"
            app:clickable="true"
            app:startColor="@color/startColor"
            app:endColor="@color/endColor" />

折线图自定义属性

Java

LineChartView lineChartView = view.findViewById(R.id.line_chart_view);
lineChartView.setyLableText("折线图");
//设置点击背景（可以为图片，也可以为一个颜色背景，大小根据textAndClickBgMargin设置）
lineChartView.setDrawBgType(DrawBgType.DrawBitmap);
//设置图片资源
lineChartView.setShowPicResource(R.mipmap.click_icon);
//连接线为虚线（也可以为实现）
lineChartView.setDrawConnectLineType(DrawConnectLineType.DrawDottedLine);
lineChartView.setClickable(true);
//是否需要画连接线
lineChartView.setNeedDrawConnectYDataLine(true);
//连接线的颜色
lineChartView.setConnectLineColor(getResources().getColor(R.color.default_color));
//是否需要背景
lineChartView.setNeedBg(true);
//画曲线图（也可以为折线图）
lineChartView.setDrawLineType(DrawLineType.Draw_Curve);

Data

private ArrayList<ChartBean> lineChartBeanList;
if(lineChartBeanList ==null){
    lineChartBeanList = new ArrayList<>();
}
lineChartView.setDefaultTextSize(24);
Random random = new Random();
for(int i=0;i<7;i++){
    ChartBean lineChartBean = new ChartBean();
    lineChartBean.setValue(String.valueOf(random.nextInt(10000)));
    lineChartBean.setDate(String.valueOf(i));
    lineChartBeanList.add(lineChartBean);
}
lineChartView.setData(lineChartBeanList);
}

柱状图

XML

  <com.veken.chartview.view.BarChartView
        android:id="@+id/bar_chart_view"
        android:layout_width="match_parent"
        android:layout_height="300dp"/>

柱状图自定义属性

其他同折线图

Java

private BarChartView barChartView;
barChartView = view.findViewById(R.id.bar_chart_view);
//是否需要柱状图的背景
barChartView.setNeedBg(true);
//Y轴文字
barChartView.setyLableText("柱状图");
//是否需要连接线
barChartView.setNeedDrawConnectYDataLine(true);
//是否需要画Y轴刻度
barChartView.setNeedDrawYScale(true);
//连接线的样式为虚线（也可以为直线）
barChartView.setDrawConnectLineType(DrawConnectLineType.DrawDottedLine);

Data

private ArrayList<ChartBean> barChartBeanList;
if(barChartBeanList == null){
    barChartBeanList = new ArrayList<>();
}
Random random = new Random();
for (int i = 0; i < 7; i++) {
    ChartBean bean = new ChartBean();
    bean.setDate(i+"");
    bean.setValue(100*random.nextInt(10)+"");
    barChartBeanList.add(bean);
}
barChartView.setData(barChartBeanList);

饼状图

XML

  <com.veken.chartview.view.PieChartView
        android:id="@+id/piechart_view"
        android:layout_width="200dp"
        android:layout_height="200dp"
        app:insideText="Hello"
        app:insideTextColor="@color/default_color"
        app:insideRadiusPercent="0.5"/>

饼状图自定义属性

Java

private PieChartView pieChartView;
pieChartView = view.findViewById(R.id.piechart_view);
//内圆中间文字
pieChartView.setInsideText("Hello");
//是否需要加载动画
pieChartView.setIsNeedAnimation(true,5000);
//是否需要背景
pieChartView.setNeedInside(false);

Data

private List<PieChartBean> mList;
if(mList==null){
    mList = new ArrayList<>();
}
//各个扇形的背景颜色
int[] colors = new int[]{getResources().getColor(R.color.colorAccent),
    getResources().getColor(R.color.default_color),
    getResources().getColor(R.color.colorPrimary),
    getResources().getColor(R.color.endColor)};
Random random = new Random();
for(int i = 0;i<4;i++){
    PieChartBean pieChartBean = new PieChartBean();
    pieChartBean.setValue(random.nextInt(10)+i);
    pieChartBean.setColor(colors[i]);
    mList.add(pieChartBean);
}
pieChartView.setData(mList);
