ChartView

ChartView是一個Android開源圖表庫。目前僅支持折線圖，曲線圖，柱狀圖，餅狀圖，以及折線圖和曲線圖點擊之后的狀態變化，可以選擇是畫一個圖片還是一個背景框。

Screens

折線圖和曲線圖:

餅狀圖有內圓:

餅狀圖沒有內圓:

Usage

Gradle

• Step 1. Add LineChartView

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

折線圖

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" />

折線圖自定義屬性

Java

LineChartView lineChartView = view.findViewById(R.id.line_chart_view);
lineChartView.setyLableText("折線圖");
//設置點擊背景（可以為圖片，也可以為一個顏色背景，大小根據textAndClickBgMargin設置）
lineChartView.setDrawBgType(DrawBgType.DrawBitmap);
//設置圖片資源
lineChartView.setShowPicResource(R.mipmap.click_icon);
//連接線為虛線（也可以為實現）
lineChartView.setDrawConnectLineType(DrawConnectLineType.DrawDottedLine);
lineChartView.setClickable(true);
//是否需要畫連接線
lineChartView.setNeedDrawConnectYDataLine(true);
//連接線的顏色
lineChartView.setConnectLineColor(getResources().getColor(R.color.default_color));
//是否需要背景
lineChartView.setNeedBg(true);
//畫曲線圖（也可以為折線圖）
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);
}

柱狀圖

XML

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

柱狀圖自定義屬性

其他同折線圖

Java

private BarChartView barChartView;
barChartView = view.findViewById(R.id.bar_chart_view);
//是否需要柱狀圖的背景
barChartView.setNeedBg(true);
//Y軸文字
barChartView.setyLableText("柱狀圖");
//是否需要連接線
barChartView.setNeedDrawConnectYDataLine(true);
//是否需要畫Y軸刻度
barChartView.setNeedDrawYScale(true);
//連接線的樣式為虛線（也可以為直線）
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);

餅狀圖

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"/>

餅狀圖自定義屬性

Java

private PieChartView pieChartView;
pieChartView = view.findViewById(R.id.piechart_view);
//內圓中間文字
pieChartView.setInsideText("Hello");
//是否需要加載動畫
pieChartView.setIsNeedAnimation(true,5000);
//是否需要背景
pieChartView.setNeedInside(false);

Data

private List<PieChartBean> mList;
if(mList==null){
    mList = new ArrayList<>();
}
//各個扇形的背景顏色
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);
