What is GraphView
GraphView is a library for Android to programmatically create
flexible and nice-looking diagrams.
It is easy to understand, to integrate and to customize.
Supported graph types:
- Line Graphs
- Bar Graphs
- Point Graphs
- or implement your own custom types.
Top Features
- Line Chart, Bar Chart, Points
- Combination of different graph types
- Scrolling vertical and horizontal
. You can scroll with a finger touch move gesture.
- Scaling / Zooming vertical and horizontal
. With two-fingers touch scale gesture (Multi-touch), the viewport can be changed.
- Realtime Graph (Live change of data)
- Second scale axis
- 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.
- Manual Y axis limits
- And much more... Check out the project page and/or the demo app

<com.jjoe64.graphview.GraphView
android:layout_width="match_parent"
android:layout_height="200dip"
android:id="@+id/graph" />
3) Add some data:
GraphView graph = (GraphView) findViewById(R.id.graph);
LineGraphSeries<DataPoint> series = new LineGraphSeries<DataPoint>(new DataPoint[] {
new DataPoint(0, 1),
new DataPoint(1, 5),
new DataPoint(2, 3),
new DataPoint(3, 2),
new DataPoint(4, 6)
});
graph.addSeries(series);
