LinearLayoutでaddViewのグラフを

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
   >

    <Button
        android:id="@+id/head"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text=" " />

    <LinearLayout
        android:id="@+id/chart"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"

    <LinearLayout
        android:layout_width="fill_parent"
