What is GraphView

• Line Charts

• Bar Charts

GraphView is a library for Android to programmatically create flexible and nice-looking diagramms. It is easy to understand, to integrate and to customize it. At the moment there are two different types:

Tested on Android 1.6, 2.2, 2.3 and 3.0 (honeycomb, tablet), 4.0.

Features

• Two chart types Line Chart and Bar Chart.

• Draw multiple series of data Let the diagram show more that one series in a graph. You can set a color and a description for every series.

• Show legend A legend can be displayed inline the chart. You can set the width and the vertical align (top, middle, bottom).

• Custom labels The labels for the x- and y-axis are generated automatically. But you can set your own labels, Strings are possible.

• Handle incomplete data It's possible to give the data in different frequency.

• Viewport You can limit the viewport so that only a part of the data will be displayed.

• Scrolling You can scroll with a finger touch move gesture.

• Scaling / Zooming Since Android 2.3! With two-fingers touch scale gesture (Multi-touch), the viewport can be changed.

• Background (line graph) Optionally draws a light background under the diagram stroke.

• Manual Y axis limits

• Realtime Graph (Live)

The mainactivity java class is as follows

package com.jitesh.helographview;

import com.jjoe64.graphview.BarGraphView;

import com.jjoe64.graphview.GraphView;

import com.jjoe64.graphview.GraphView.GraphViewData;

import com.jjoe64.graphview.GraphViewSeries;

import com.jjoe64.graphview.LineGraphView;

import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

import android.widget.LinearLayout;

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

GraphViewSeries exampleSeries = new GraphViewSeries(new GraphViewData[] {

         new GraphViewData(1, 2.0d)

         , new GraphViewData(2, 1.5d)

         , new GraphViewData(3, 2.5d)

         , new GraphViewData(4, 1.0d)

});

GraphView graphView = new BarGraphView(

     this // context

     , "GraphViewDemo" // heading

);

// GraphView graphView = new LineGraphView(

//      this // context

//      , "GraphViewDemo" // heading

// );

graphView.addSeries(exampleSeries); // data

LinearLayout layout = (LinearLayout) findViewById(R.id.layout);

layout.addView(graphView);

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.activity_main, menu);

return true;

}

}

activity_main.xml is as below

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    tools:context=".MainActivity" android:id="@+id/layout">

</LinearLayout>
