#ZqxChart 折线图,柱状图 饼状图 maven:

<dependency>
    <groupId>com.zqx.chart</groupId>
    <artifactId>chart</artifactId>
    <version>0.2</version>
    <type>pom</type>
</dependency>

gradle:

compile 'com.zqx.chart:chart:0.2'

使用方法:

1.折线图

  //通过代码设置:
  LineChart lineChart = (LineChart) findViewById(R.id.linechart);
  LineChartData lineChartData = LineChartData.builder()
          .setXdata(xdata)//x轴数据
          .setYdata(ydata)//y轴数据
          .setYpCount(7)//y轴刻度数量
          .setCoordinatesColor(getResources().getColor(android.R.color.holo_orange_dark))
          //.setXXX()
          .setAnimType(Anim.ANIM_ALPHA)//动画效果,目前仅支持两种
          .build();
  lineChart.setChartData(lineChartData);
  //通过xml设置:
  <?xml version="1.0" encoding="utf-8"?>
  <LinearLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:chart="http://schemas.android.com/apk/res/com.zqx.zqxcharts" <!-- 此处指定自己的包名 -->
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:orientation="vertical">
  
          <com.zqx.chart.view.LineChart
              android:layout_marginTop="5dp"
              android:id="@+id/linechart"
              android:layout_width="match_parent"
              android:layout_height="200dp"
              android:layout_marginRight="5dp"
              chart:lCoordinatesColor="@color/colorAccent" 
              chart:lxTextColor="@color/colorAccent"
              chart:lyTextColor="@color/colorAccent"
              chart:pointColor="@color/colorAccent"
              />
        
  </LinearLayout>
  // res/下新建 attrs.xml
  <!-- 折线图样式属性 -->
  <declare-styleable name="zqxchart_line">
      <!-- 坐标系颜色 -->
      <attr name="lCoordinatesColor" format="color"/>
      <!-- 折点颜色 -->
      <attr name="pointColor" format="color"/>
      <!-- 折点文字颜色 -->
      <attr name="pointTextColor" format="color"/>
      <!-- 折点文字尺寸 -->
      <attr name="pointTextSize" format="integer"/>
      <!-- 折线颜色 -->
      <attr name="lineColor" format="color"/>
      <!-- x轴文字颜色 -->
      <attr name="lxTextColor" format="color"/>
      <!-- y轴文字颜色 -->
      <attr name="lyTextColor" format="color"/>
      <!-- x轴文字尺寸 -->
      <attr name="lxTextSize" format="integer"/>
      <!-- y轴文字尺寸 -->
      <attr name="lyTextSize" format="integer"/>
      <!-- x轴刻度点数量 -->
      <attr name="lxPointCount" format="integer"/>
      <!-- y轴刻度点数量 -->
      <attr name="lyPointCount" format="integer"/>
      <!-- 折线宽度 -->
      <attr name="line_width" format="float"/>
      <!-- 折点尺寸 -->
      <attr name="point_size" format="float"/>
      <!-- 折线样式是否闭合 -->
      <attr name="lPathStyle">
          <enum name="STROKE" value="0"></enum>
          <enum name="FILL" value="1"></enum>
      </attr>
  </declare-styleable>

2.柱状图

  //通过代码设置
  Histogram histogramChart = (Histogram) findViewById(R.id.histogramchart);
  HistogramData histogramData = HistogramData.builder()
          .setXdata(xdata)
          .setYdata(ydata)
          .setYpCount(7)
          .setAnimType(Anim.ANIM_ALPHA)
          .build();
  histogramChart.setChartData(histogramData);
  #通过xml设置
  <com.zqx.chart.view.LineChart
        android:layout_marginTop="5dp"
        android:id="@+id/linechart"
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:layout_marginRight="5dp"
        chart:lCoordinatesColor="@color/colorAccent"
        chart:lxTextColor="@color/colorAccent"
        chart:lyTextColor="@color/colorAccent"
        chart:pointColor="@color/colorAccent"
        />
  <!-- 柱状图样式属性 -->
  <declare-styleable name="zqxchart_histogram">
      <!-- 坐标系颜色 -->
      <attr name="hCoordinatesColor" format="color"/>
      <attr name="rectTextColor" format="color"/>
      <attr name="rectTextSize" format="integer"/>
      <!-- x轴文字颜色 -->
      <attr name="hxTextColor" format="color"/>
      <!-- y轴文字颜色 -->
      <attr name="hyTextColor" format="color"/>
      <!-- x轴文字尺寸 -->
      <attr name="hxTextSize" format="integer"/>
      <!-- y轴文字尺寸 -->
      <attr name="hyTextSize" format="integer"/>
      <!-- x轴刻度点数量 -->
      <attr name="hxPointCount" format="integer"/>
      <!-- y轴刻度点数量 -->
      <attr name="hyPointCount" format="integer"/>
  </declare-styleable>
  //也可以通过代码和 arrays.xml 设置每个x坐标对应柱状图的颜色,代码可以通过新建一个color 数组并调用
      setColors(xxx);
  //arrays.xml color 个数与数据个数对应
    <!-- 柱状图颜色属性 -->
    <integer-array name="histogram_color" >
        <item>@android:color/darker_gray</item>
        <item>@android:color/holo_red_dark</item>
        <item>@android:color/holo_green_dark</item>
        <item>@android:color/holo_orange_dark</item>
        <item>@color/histogram_test</item>
        <item>@android:color/holo_blue_dark</item>
        <item>@color/colorAccent</item>
    </integer-array>

3.饼状图

    饼状图动画效果目前只支持alpha
    code:
        PieChart pieChart = (PieChart) findViewById(R.id.piechart);
        int[] colors = new int[]{Color.RED,Color.BLACK,Color.BLUE,Color.GREEN,Color.GRAY,
                Color.YELLOW,Color.LTGRAY,Color.CYAN,Color.MAGENTA};
        PieChartData pieChartData = PieChartData.builder()
                .setDatas(datas)
                //.setColors(colors)
                .setTextColor(Color.RED)
                //.setTextSize(36)
                //.setSeparationDegree(3)
                .setPieItemClickListener(new OnPieItemClickListener() {
                    @Override
                    public void onPieItemClick(int position) {
                        Toast.makeText(MainActivity.this,"click->"+position,Toast.LENGTH_SHORT).show();
                    }
                }).build();
        pieChart.setChartData(pieChartData);
    xml:
        <com.zqx.chart.view.PieChart
              android:id="@+id/piechart"
              android:layout_width="match_parent"
              android:padding="5dp"
              android:layout_height="400dp"
              chart:textColor="@color/colorAccent"
              chart:textSize="40"
              />
    <!-- 饼状图颜色属性 -->
    <integer-array name="pie_colors" >
      <item>@color/colorPrimary</item>
      <item>@android:color/darker_gray</item>
      <item>@android:color/holo_red_dark</item>
      <item>@android:color/holo_green_dark</item>
      <item>@android:color/holo_orange_dark</item>
      <item>@android:color/white</item>
      <item>@android:color/holo_blue_dark</item>
      <item>@color/colorAccent</item>
      <item>@android:color/black</item>
    </integer-array>
    饼状图自定义属性
    <declare-styleable name="zqxchart_pie">
        <!-- 间隔角度 -->
        <attr name="separationDegree" format="integer"/>
        <!-- 文字颜色 -->
        <attr name="textSize" format="integer"/>
        <!-- 文字颜色 -->
        <attr name="textColor" format="color"/>
        <!-- 动画效果 -->
        <attr name="panimType">
            <enum name="NONE" value="-1"></enum>
            <!--enum name="TRANSLATE" value="0"></enum-->
            <enum name="ALPHA" value="1"></enum>
        </attr>
    </declare-styleable>

待完成

折线图和柱状图的多组数据显示。
